Wash hands before and after palpating gastritis diet åëüäîðàäî cheap bentyl 10 mg with mastercard, inserting, replacing, or dressing any intravascular access site. However, if the infusions consist of hypertonic substances, vasopressors, or chemotherapeutics, there is a significant risk for skin sloughing if infiltration and extravasation occur (Box 21. Pain at the infusion site or the alarm sounding on an infusion pump device requires inspection of the infusion site for extravasation. Reversal of ischemia with phentolamine is a common technique, but its ability to totally reverse or prevent skin sloughing is not guaranteed. However, if infiltration of these vasopressors occurs, the authors suggest that it be used routinely. There are few downsides to this intervention, although hypotension is a theoretical side effect because phentolamine is an -adrenergic antagonist. To inject phentolamine, place 5 mg in a vial and dilute with equal parts of saline (final form: 5 mg in 2 mL). For large areas, use two vials with the contents of each vial injected 10 minutes apart through a 25- to 27-gauge needle or a tuberculin syringe. The entire area of skin blanching, or suspected area of extravasation, is injected with multiple small aliquots of the solution, approximately 0. Hyaluronidase is probably benign and has been suggested in the past to ameliorate some effects of extravasation of other solutions. Aminophylline Calcium chloride 10% Carmustine Chlordiazepoxide Colchicine Crystalline amino acids 4. Thus, any complaint of pain during infusion or signs of tissue swelling should prompt an investigation for extravasation. Phentolamine, injected subcutaneously to reverse vasoconstriction, is the most common technique, but its efficacy has not been well studied. Extravasation of hypertonic dextrose, phenytoin, and vasoconstrictors or vasopressors will cause similar necrosis. B, Full-thickness tissue injury from doxorubicin extravasation, not obvious until 7 to 10 days after the infusion. The patient may complain of pain and burning at the time of infusion, but skin sloughing may be delayed for many days. Injury from extravasation of phenytoin can be minimized or avoided by using dilute solutions, no more than a 2-mg/ mL concentration (1 g in 500 mL saline), or by using fosphenytoin instead of phenytoin. Multiple subcutaneous injections in and around the area of extravasation with a 25-gauge needle: 4 mL of 10% sodium thiosulfate + 6 mL water. Inject subcutaneously in and around the area of extravasation with a 25-gauge needle: 150 units (1 mL). Inject subcutaneously in and around the area of extravasation with a 25-gauge needle. Inject subcutaneously in and around the area of extravasation with a 25-gauge needle: hydrocortisone, 500 mg diluted in 500 mL saline.

Threading the wire through the side port allows the tip of the tube to protrude 1 cm beyond the point at which the wire enters the larynx gastritis diet 60 purchase bentyl on line. Because retrograde intubation is a blind technique, it may be difficult to determine whether the tube has entered the trachea or is impeded by more proximal structures. If in doubt, pull the tube back 2 cm, rotate it 90 degrees counterclockwise, and then readvance the tube. A significant advance has been the addition of a plastic sheath that is passed antegrade over the wire until it meets resistance where the wire penetrates the laryngeal mucosa. If a sheath is available, after grasping the wire from the mouth, thread the plastic sheath over the wire until it comes to rest against the anterior laryngeal wall. If any resistance at the arytenoids or vocal cords is encountered, pull the tube back 1 to 2 cm and rotate it 90 degrees counterclockwise. One advantage of the antegrade sheath is that it lies freely in the larynx, allowing more posterior passage through the widest distance between the cords. The potential for hemorrhage is minimized by taking care to puncture the cricothyroid membrane in its lower half to avoid the cricothyroid artery. Subcutaneous emphysema may occur, but it is of no clinical significance because no air is insufflated during this technique. A small incidence of soft tissue infection is reported with translaryngeal needle procedures, and ensuring that the wire is withdrawn from the mouth rather than the neck can minimize this problem. The final complication, failure to achieve intubation, has been mitigated by addition of the antegrade sheath over the wire. Summary Retrograde intubation is an underused technique for achieving tracheal intubation in a patient who cannot be intubated by less aggressive means. A method of replacing the tube without losing control of the tracheal lumen is preferred. This can be achieved by passing a guide down the defective tube, withdrawing the tube while leaving the guide in place, and introducing a new tube over the guide and into the trachea. Tracheal Retrograde Intubation 1 Place a saline-filled needle through the cricothyroid membrane. B) Pass the antegrade sheath over the wire into the trachea while keeping both ends of the wire taut. This is the critical portion of the procedure because only a small portion of the sheath is in the trachea. Bougies are generally easier to locate in the airway cart and intubators are more familiar with their use. They most often occur when patients suddenly pull out their own tube or during transport.

Urethra: a canal that passes through the prostate gland gastritis diet ùë bentyl 10 mg buy low price, enters the penis, and conveys the semen for expulsion from the body during ejaculation. Anterior cavities: include the thoracic and abdominopelvic cavities, separated by the respiratory radiologyme. Subsequent cell division (cleavage) occurs at the two-, four-, eight-, and 16-cell stages and results in formation of a ball of cells that travels down the uterine tube toward the uterine cavity. When the cell mass reaches days 3 to 4 of development, it resembles a mulberry and is called a morula (16-cell stage). As the growing Myometrium morula enters the uterine cavity at about day 5, it contains hundreds of cells and it develops a luidilled cyst in its interior; it is now known as a blastocyst. At about days 5 to 6, implantation occurs as the blastocyst literally erodes or burrows its way into the uterine wall (endometrium). Clinical Focus 1-8 Potential Spaces Each of these spaces-pleural, pericardial, and peritoneal-is considered a "potential" space, because between the parietal and visceral layers, there is usually only a small amount of serous lubricating fluid, to keep organ surfaces moist and slick and thus reduce friction from movements such as respiration, heartbeats, and peristalsis. However, during inflammation or trauma (when pus or blood can accumulate), fluids can collect in these spaces and restrict movement of the viscera. In such situations, these "potential" spaces become real spaces, and the offending fluids may have to be removed so they do not compromise organ function or exacerbate an ongoing infection. Week 2: Formation of the Bilaminar Embryonic Disc As the blastocyst implants, it forms an inner cell mass (future embryo, embryoblast) and a larger luid-illed cavity surrounded by an outer cell layer called the trophoblast. Simultaneously, the inner cell mass develops into the following two cell types (bilaminar disc formation): Epiblast: formation of a sheet of columnar cells on the dorsal surface of the embryoblast. About day 12, further hypoblast cell migration forms the true yolk sac, and the old blastocyst cavity becomes coated with extraembryonic mesoderm. Week 3: Gastrulation Gastrulation (development of a trilaminar embryonic disc) begins with the appearance of the primitive streak on the dorsal surface of the epiblast. Migrating epiblast cells move toward the primitive streak, invaginate, and replace the underlying hypoblast cells to become the endoderm germ layer. Other invaginating epiblast cells develop between the endoderm and overlying epiblast and become the mesoderm. As you study each region of the body, refer to these summary pages to review the embryonic origins of the various tissues. Many clinical problems arise during the development in utero of these germ layer derivatives. As the x-rays (a form of electromagnetic radiation) pass through the body, they lose energy to the tissues, and only the photons with suicient energy to penetrate the tissues then expose a sheet of photographic ilm.

Examples of several nerve lesions are featured in Section 10 (Upper Limb Nerve Summary) and in the Clinical Focus boxes later in this chapter gastritis diet for diabetics discount bentyl 10 mg mastercard. Despite the complexity of the brachial plexus, its sensory (dermatome) distribution throughout the upper limb is segmental, beginning proximally and laterally over the deltoid muscle and radiating down the lateral arm and forearm to the lateral aspect of the hand. Chapter 7 Upper Limb 383 7 Clinical Focus 7-7 Axillary Lipoma Benign soft tissue tumors occur much more often than malignant tumors. Presenting as a solitary mass, a lipoma is usually large, soft, and asymptomatic and is more common than all other soft tissue tumors combined. Excised tumor with muscle at margin; tumor darker and firmer than benign lipoma C8: medial two digits (fourth and ifth digits), hypothenar eminence, and medial forearm. T2: from the intercostobrachial nerve to the skin of the axilla (not part of the brachial plexus). Axillary Lymph Nodes he axillary lymph nodes lie in the fatty connective tissue of the axilla and are the major collection nodes for all lymph draining from the upper limb and portions of the thoracic wall, especially the breast. Lymph from the breast also can drain superiorly into infraclavicular nodes, into pectoral nodes, medially into parasternal nodes, and inferiorly into abdominal trunk nodes (see also. Anterior Compartment Arm Muscles, Vessels, and Nerves Muscles of the anterior compartment exhibit the following features. Are secondarily lexors of the arm at the shoulder (biceps and coracobrachialis muscles). Are supplied with blood from the profunda brachii (deep brachial) artery and its muscular branches. A rich anastomosis exists around the elbow joint between branches of the brachial artery and branches of the radial and ulnar arteries. One can feel a brachial pulse by pressing the artery medially at the midarm against the underlying humerus. Medial epicondyle of humerus Olecranon of ulna Posterior antebrachial cutaneous n. Arm in Cross Section Cross sections of the arm show the anterior and posterior compartments and their respective lexor and extensor muscles. Note the nerve of each compartment and the medially situated neurovascular bundle containing the brachial artery, median nerve, and ulnar nerve. Lateral intermuscular septum Medial head Lateral head Long head Medial brachial cutaneous n. Anterior Compartment Forearm Muscles, Vessels, and Nerves he muscles of the anterior compartment of the forearm are arranged in two layers, with the muscles of the supericial layer largely arising from the medial epicondyle of the humerus, although several muscles also arise from the ulna and/or radius or interosseous membrane. Speciically, it is the deeper group of anterior forearm muscles that typically arise from the ulna, the radius, and/or the interosseous membrane. If pathology is involved at the level tested, the reflex may be weak or absent, requiring further testing to determine where along the pathway the lesion occurred. Humeral fractures also may occur along the midshaft, usually from direct trauma, or distally (uncommon in adults). Rupture is seen most often in patients older than 40, in association with rotator cuff injuries (as the tendon begins to undergo degenerative changes), and with repetitive lifting.

Be sure to feel the pulse with your index and/ or middle finger gastritis diet sweet potato 10 mg bentyl purchase with mastercard, and not your thumb. If you use your thumb, you may be sensing you own pulse and not that of your patient! The pronator quadratus muscle extends between the distal ulna and radius, is innervated by the median nerve, and is the deepest of the anterior compartment muscles of the forearm. The distal fragment is displaced dorsally and proximally, giving the wrist and hand the appearance of a dinner fork (see Clinical Focus 7-15). The capitate (round) carpal is in the distal row of carpals and articulates with the base of the middle (third) metacarpal. Dislocation of the head of the humerus often happens in an anterior and slightly inferior direction, with the head coming to lie just beneath the coracoid process (a subcoracoid dislocation). The supraspinatus muscle lies superior to the spine and initiates abduction of the arm at the shoulder. The clavicle is a bit unusual because it ossifies by intramembranous ossification, is one of the first bones to ossify, and is one of the last bones to fuse. All of the other bones of the appendicular skeleton ossify by endochondral bone formation. Nasal cavities and paranasal sinuses: form the uppermost part of the respiratory system. Neurovascular: two anterolateral compartments that contain the common carotid artery, internal jugular vein, and vagus nerve; all are contained within a fascial sleeve called the carotid sheath. Prevertebral: posterocentral compartment that contains the cervical vertebrae and the associated paravertebral cervical muscles. Zygomatic bone: the cheekbone, which protrudes below the orbit and is vulnerable to fractures from facial trauma. Ear (auricle or pinna): skin-covered elastic cartilage with several consistent ridges, including the helix, antihelix, tragus, antitragus, and lobule. Jugular (suprasternal) notch: midline depression between the two sternal heads of the sternocleidomastoid muscle. Eight of these bones form the cranium (neurocranium, which contains the brain and 437 438 Chapter 8 Head and Neck Supraorbital notch Superciliary arch Infraorbital margin Zygomatic bone Helix Nasal bone Tragus Ala of nose Antihelix Antitragus Lobule Philtrum Commissure of lips Angle of mandible Submandibular gland Tubercle of superior upper lip External jugular v. Clavicle Glabella Anterior nares (nostrils) Nasolabial sulcus Thyroid cartilage Clavicular head of sternocleidomastoid m. Using your atlas and dry bone specimens, note the complexity of the maxillary, temporal, and sphenoid bones. Pterion: point at which frontal, sphenoid, temporal, and parietal bones meet; the middle meningeal artery lies beneath this region. Comminuted: presents with multiple fragments (depressed if driven inward; can compress or tear the underlying dura mater). Any fracture that communicates with a lacerated scalp, a paranasal sinus, or the middle ear is termed a compound fracture.

A potentially explosive environment is a relative contraindication to defibrillation chronic gastritis joint pain order bentyl 10 mg free shipping. Although it is unlikely that there will be any significant or dangerous current leaks from the patient onto a wet floor, take care to avoid creating an electrical hazard. Try to ensure that the area is not wet; however, a wet surface is not an absolute contraindication to defibrillation. This may be a function of perpendicular electrode orientation with respect to the wavefront of depolarization. High impedance or resistance to flow of current can compromise the amount of current actually delivered to the myocardium and lead to a failed first shock. Inappropriate use of conductive material can result in current bridging or a short circuit and arcing of electrical current secondary to streaking of the material across the chest. In addition, arcing of electricity can become a possible explosion hazard, depending on the circumstances. Various electrode gels are available on the market and should be kept in the proximity of the defibrillator, on the prearranged cart ready to use. Self-adhesive pad electrodes now have a resistance-reducing, conductive material incorporated into the adhesive, thus rendering the use of a gel or other conductive material unnecessary. A, If standard defibrillation paddles are being used, electrode gel must be applied before the procedure. B, Self-adhesive pad electrodes have conductive material incorporated into the adhesive. As soon as the defibrillator is available and the patient is connected to the monitor, assess the rhythm. If a pulse is definitely present, provide 1 breath for 1 second every 5 to 6 seconds or 8 to 10 breaths/min. Observe the patient for visible chest wall rise and fall so that the thorax does not become overinflated. Hyperinflation of the chest can lead to inadvertent pressurization of the esophagus, which can cause lower esophageal sphincter pressure to be exceeded. This can lead to retrograde flow of gastric contents into the esophagus with the potential for subsequent aspiration of acid and debris into the trachea if the airway is not adequately protected. Overventilation of the thorax can also lead to an increase in intrathoracic pressure and impedance of blood flow to and from the heart, which should be avoided. If no pulse is present, begin a sequence of 30 chest compressions followed by 2 ventilations/breaths. Keep your hands on the lower half of the sternum and compress it at least 2 inches (5 cm) at a rate of at least 100 compressions/min. The time allotted for compression should be 50%/50% for compression and relaxation of the chest.

Eyelids and Lacrimal Apparatus he eyelids protect the eyeballs and keep the corneas moist gastritis diet øàðàðàì generic bentyl 10 mg on-line. Tears not only keep the eye surface moist but also possess antimicrobial properties. Lacrimal canaliculi: collect tears into openings on the medial aspect of each lid called the puncta, and convey them to the lacrimal sacs. Lacrimal sacs: collect tears and release them into the nasolacrimal duct when one blinks (contraction of the orbicularis oculi muscle). Chapter 8 Head and Neck 469 8 Clinical Focus 8-20 Orbital Blow-Out Fracture A massive zygomaticomaxillary complex fracture or a direct blow to the front of the orbit. In severe comminuted fractures of the orbital floor, the orbital soft tissues may herniate into the underlying maxillary paranasal sinus. Clinical signs include diplopia, infraorbital nerve paresthesia, enophthalmos, edema, and ecchymosis. Clinical findings Limitation of upward gaze caused by entrapment of tissue in fracture defect Anesthesia of cheek from damage to infraorbital nerve Infraorbital nerve Lowered globe level caused by prolapse of large volume of soft tissue into maxillary sinus Retinal detachment Defect in orbital floor Hyphema Hemorrhage and rupture of globe Dislocated lens Serious ocular injuries resulting from blow-out fractures Maxillary sinus Nasolacrimal ducts: convey tears from lacrimal sacs to the inferior meatus of the nasal cavity. However, the generalist physician can check extraocular muscle (or nerve) impairment by assessing the ability of individual muscles to elevate or depress the globe with the eye abducted or adducted, thereby aligning the globe with the pull (line of contraction) of the muscle. Generally, intorsion and extorsion are too difficult to assess in a routine eye examination. Pure abduction is done by the lateral rectus muscle, and pure adduction is done by the medial rectus muscle. At the end of this test, the examiner can bring the finger directly to the midline to test convergence (medial rectus muscles). If an eye movement disorder is detected by this method, a clinical specialist may be consulted for further evaluation. In addition to the movements of elevation, depression, abduction, and adduction, the superior rectus and superior oblique muscles medially rotate (intorsion) the eyeball, and the inferior rectus and inferior oblique muscles laterally rotate (extorsion) the eyeball. For example, two muscles elevate the eyeball (superior rectus and inferior oblique muscles), and three muscles abduct the eyeball (lateral rectus, superior oblique, and inferior oblique muscles). The cardinal signs are as follows: Ptosis: partial drooping of the upper eyelid on the affected side caused by paralysis of the superior tarsal smooth muscle in the free edge of the levator palpebrae superioris muscle. Miosis: pupillary constriction on the affected side caused by the paralysis of the pupillary dilator smooth muscle in the iris. Anhidrosis: loss of sweating on the affected side of the head caused by loss of sweat gland innervation by the sympathetic fibers. Flushed, warm dry skin: vasodilation of the subcutaneous arteries on the affected side caused by a lack of sympathetic vasoconstriction tone and sweat gland innervation. Interruption of the sympathetic fibers outside the brain causes ipsilateral ptosis, anhidrosis, and miosis without abnormal ocular mobility.

Chapter 7 Upper Limb 433 7 For each of the structures described below (38-40) gastritis diet 411 bentyl 10 mg buy amex, select the label (A-H) from the radiograph of the shoulder joint that best matches the description. The biceps tendon reflex tests the musculocutaneous nerve and especially the C5-C6 contribution. The triceps tendon reflex tests the C7-C8 spinal contributions of the radial nerve. The radial nerve spirals around the posterior aspect of the midhumeral shaft and can be stretched or contused by a compound fracture of the humerus. This nerve innervates all the extensor muscles of the upper limb (posterior compartments of the arm and forearm). Repeated abduction and flexion can cause the tendon to rub on the acromion and coracoacromial ligament, leading to tears or rupture. The thenar muscles are located at the base of the thumb and are innervated by the median nerve, which passes through the carpal tunnel and is prone to injury in excessive repetitive movements at the wrist. Just above this bony feature lies the muscle that initiates abduction at the shoulder. The ulnar nerve is subcutaneous as it passes around the medial epicondyle of the humerus. In this location, it is vulnerable to compression injury against the bone ("funny bone") or entrapment in the cubital tunnel (beneath the ulnar collateral ligament). The radial pulse can be easily taken at the wrist where the radial artery lies just lateral to the tendon of the flexor carpi radialis muscle. The proximal fragment will be flexed and supinated by the biceps brachii and supinator muscles, while the distal fragment will be pronated by the action of the pronator teres and pronator quadratus muscles. The median cubital vein may drain into the basilic vein, which then dives deeply and drains into the axillary vein. Fractures of the clavicle are relatively common and occur most often in the middle third of the bone. The distal fragment is displaced downward by the weight of the shoulder and drawn medially by the action of the pectoralis major, teres major, and latissimus dorsi muscles. This laceration probably severed the long thoracic nerve, which innervates the serratus anterior muscle. During muscle testing, the scapula will "wing" outwardly if this muscle is denervated. Fractures of this portion of the humerus can place the axillary nerve in danger of injury. Her muscle weakness confirms that the deltoid muscle especially is weakened, and the deltoid and teres minor muscles are innervated by the axillary nerve.

If the tracheostomy stoma was created less than 7 days earlier gastritis que no comer purchase bentyl with a visa, be prepared to orally intubate the patient. Stay sutures may be placed to hold the stoma open and better visualize the tracheal opening. If the patient is stable, attempt to reinsert the tracheostomy tube with the assistance of a gum elastic bougie or fiberoptic scope. If the tracheostomy stoma was created 7 to 30 days earlier, remove the tube and any other cause of obstruction from the stoma. If the patient can ventilate independently, allow the patient to oxygenate and then reinsert the tube when ready. If the patient is unstable, occlude the stoma with moist gauze or other occlusive device and provide bag-valve-mask ventilation. If the tracheostomy is more than 30 days old, the tube may not need to be replaced. If the patient is stable and ventilating spontaneously without any signs of distress, contact the appropriate specialty care physician to discuss the need for emergency reinsertion. Once the tube is reinserted, confirm correct placement with auscultation and waveform capnography. Tube position can also be confirmed by direct visualization with a fiberoptic scope. Obese patients are at high risk for false passage because of their redundant neck tissue (see section on Special Populations). Subcutaneous air, crepitus, or distortion of anterior neck landmarks may indicate placement of the tracheostomy tube into a false passage. Absence of a waveform on capnography confirms misplacement of the tracheostomy tube. If a false passage is suspected, remove and replace the tracheostomy tube expeditiously. When fractures do occur, they are most often located at the juncture of the flange and the tube connection. Patients may have acute respiratory complaints such as cough, dyspnea, choking, or wheezing. Prolonged retention of a foreign body can result in chronic respiratory symptoms such as wheezing, coughing, or recurrent bouts of pneumonia or bronchiectasis. To manage this problem, replace the tube if possible and consider bronchoscopy for retrieval of the tube fragment. Mucosal injury is less common since the use of low-pressure cuffs has become standard practice. Pain with ventilation or swallowing, inadequate oxygenation, or the presence of gastric secretions in the tracheostomy tube may indicate cuff problems. Verify inflation pressure with a manometer (target range, 18 to 25 mm Hg) and appropriate cuff position. In general, the frequency of infection increases with the duration of mechanical ventilation, and the risk for infection is highest in the first week following intubation.

Spike, 65 years: If the sagittal suture closes prematurely, growth in width is altered, so growth occurs lengthwise and leads to a long, narrow cranium; coronal and lambdoid suture closure results in a short, wide cranium. The procedures most often associated with this injury are cardiac catheterization (angioplasty or valvuloplasty) and pacemaker insertion.

Vandorn, 62 years: In a cooperative patient, determine this by simply occluding each nostril and asking the patient to identify the nostril that is easiest to breathe through. Common ulcer sites are shown in the figure, with more than half associated with the pelvic girdle (sacrum, iliac crest, ischium, and greater trochanter of femur).

Tempeck, 46 years: Avoid veins that are not resilient and feel hard or cordlike because they are often thrombosed. Time becomes critical as the risk for irreversible hypoxic injury and cardiac arrest rises.

Pakwan, 26 years: Laryngoscope-induced trauma, edema, and foreign material will significantly alter the diameter of the airway. Firm compression over the puncture site will almost always result in hemostasis in 5 minutes or less.

Saturas, 61 years: Sensation on the dorsum of the foot is largely conveyed by the medial and intermediate dorsal cutaneous nerves of the superficial fibular nerve. Both surgical cricothyrotomy and needle cricothyrotomy entail puncture of the cricothyroid membrane through the overlying skin to gain access to the airway.

Arokkh, 50 years: In this patient the pneumothorax is readily visualized, with no lung markings seen laterally or superior to the pleural reflection (white arrows). Lift the pericardial sac with toothed forceps, and use scissors to make a small hole.

These concerns are essentially theoretical, with no credible data to prove or disprove a true effect.

Chenor, 59 years: Double break in continuity of anterior pelvic ring causes instability but usually little displacement. For example, a 50-kg child would require (100 ml × 10 kg) + (50 ml × 10 kg) + (20 ml × 30 kg) divided evenly over 24 hours.

Umbrak, 27 years: Lifestyle advice should be continually reinforced, while also providing support for smoking cessation and lipid management. However, some lymph from the perineum and the vestibule of the vagina and lymph that courses along the round ligament of the uterus (which passes through the inguinal canal) also drains into the superficial inguinal nodes.

Dawson, 32 years: The upper part of the neck will naturally extend when the head tilts backward during this maneuver. Heart he heart is a hollow muscular (cardiac muscle) organ that is divided into four chambers.

Hamlar, 25 years: Blood Supply to the Orbit and Eye he ophthalmic artery arises from the internal carotid artery just as it exits the cavernous sinus, and it supplies the orbit and eye by the following branches. Visceral afferent fibers convey pelvic sensory information (largely pain) via both the sympathetic fibers (to the upper lumbar spinal cord [L1-L2] or lower thoracic levels [T11-T12]) and parasympathetic fibers (to the S2-S4 levels of the spinal cord).

Tufail, 22 years: When mask ventilation is technically difficult, higher peak airway pressure is often required to provide adequate tidal volume. The safety of etomidate and ketamine are the main challenges to the routine use of propofol for intubation.

Stejnar, 43 years: Slight resistance was noted in one patient with right main stem intubation; the resistance decreased when the tube was pulled back. It receives its arterial supply primarily from the celiac trunk (splenic artery and gastroduodenal branch from the common hepatic branch of the celiac artery) and also from branches of the superior mesenteric artery (inferior pancreaticoduodenal branches; see.
