Another technique generic duphalac 100 ml on line, the PICC line is designed for more long-term outpatient administration of med- ications and is described on page 292. Materials Commercially available disposable trays provide all the necessary needles, wires, sheaths, dilators, suture materials, and anesthetics. If needles, guidewires, and sheaths are collected from different places, it is very important to make sure that the needle will accept the guidewire, that the sheath and dilator will pass over the guidewire, and that the appliance to 13 be passed through the sheath will indeed fit the inside lumen of the sheath. Supplies should include the following items: • Minor procedure and instrument tray (page 240); 1% lidocaine (mixed 1:1 with sodium bicarbonate 1 mEq/L removes the sting) • Guidewire (usually 0. Hemodynamic measurements are often easier to record from the left subclavian approach. From the left subclavian vein approach, the catheters do not have to negotiate an acute angle, as is commonly the case at the junction of the right subclavian with the right brachiocephalic vein en route to the superior vena cava. It also has the lowest risk of infection of various cen- 13 Bedside Procedures 255 tral line sites. However, remember that the thoracic duct is on the left side, and the dome of the pleura rises higher on the left. Use sterile technique (povidone–iodine prep, gloves, mask, and a sterile field) when- ever possible. Place the patient flat or head down in the Trendelenburg position with the head in the center or turned to the opposite side (the “ideal” position is somewhat controversial, and left up to operator preference). Use a 25-gauge needle to make a small skin wheal 2 cm below the midclavicle with 1% lidocaine (mixed 1:1 with sodium bicarbonate 1 mEq/L to help remove the sting). At this point, a larger needle (eg, 22-gauge) can be used to anesthetize the deeper tis- sues as well as locate the vein. Attach a large-bore, deep-line needle (a 14-gauge needle with a 16-gauge catheter at least 8–12 in. Advance the needle under the clavicle, aiming for a location halfway between the suprasternal notch and the base of the thyroid cartilage. The vein is encountered under the clavicle, just medial to the lateral border of the clavicular head of the sternocleido- mastoid muscle. In most patients this is roughly two finger-breadths lateral to the ster- nal notch.

This close relationship between the origins of the oesophagus and trachea accounts for the relatively common malformation in which the upper part of the oesophagus ends blindly while the lower part opens into the lower trachea at the level of T4 (oesophageal atresia with tracheo- oesophageal fistula) generic duphalac 100 ml without prescription. Less commonly, the upper part of the oesophagus opens into the trachea, or oesophageal atresia occurs without concomitant fistula into the trachea. The thoracic duct (Figs 37, 213) The cisterna chyli lies between the abdominal aorta and right crus of the diaphragm. It drains lymphatics from the abdomen and the lower limbs, then passes upwards through the aortic opening to become the thoracic duct. This ascends behind the oesophagus, inclines to the left of the oesoph- agus at the level of T5, then runs upwards behind the carotid sheath, descends over the subclavian artery and drains into the commencement of the left brachiocephalic vein (see Fig. The left jugular, subclavian and mediastinal lymph trunks, draining the left side of the head and neck, upper limb and thorax respectively, usually join the thoracic duct, although they may open directly into the adjacent large veins at the root of the neck. The upper oesophagus ends blindly; the lower oesophagus communicates with the trachea at the level of the 4th thoracic vertebra. Jugular lymph Oesophagus Subclavian trunk Left subclavian vein Left brachiocephalic Superior vein vena cava Azygos vein Thoracic duct Cisterna chyli Fig. The mediastinum 47 The thoracic duct thus usually drains the whole lymphatic field below the diaphragm and the left half of the lymphatics above it. On the right side, the right subclavian, jugular and mediastinal trunks may open independently into the great veins. Usually the subclavian and jugular trunks first join into a right lymphatic duct and this may be joined by the mediastinal trunk so that all three then have a common opening into the origin of the right brachiocephalic vein. Clinical features 1The lymphatics may become blocked by infection and fibrosis due to the Microfilaria bancrofti. This usually results in lymphoedema of the legs and scrotum but occasional involvement of the main channels of the trunk and thorax is followed by chylous ascites, chyluria and chylous pleural effusion. If noticed at operation, the injured duct should be ligated; lymph then finds its way into the venous system by anastomosing channels.

Resources Because of the relatively benign nature of the condi- tion, there has been no reported scientific work trying to BOOKS locate the gene responsible for the syndrome. Occurrence of the ACHOO syndrome is widespread “Health Supervision for Children With Achondroplasia.

Red and green go to the legs: “Christmas on the bottom” or “When driving your car you use your left leg to brake (red light) and your right leg to go (green light).

ENDOTRACHEAL INTUBATION Indications • Airway management during cardiopulmonary resuscitation 13 • Any indication for using mechanical ventilation (respiratory failure, coma, general anesthesia, etc) Contraindications • Massive maxillofacial trauma (relative) • Fractured larynx • Suspected cervical spinal cord injury (relative) Materials • Endotracheal tube of appropriate size (Table 13–3) • Laryngoscope handle and blade (straight [Miller] or curved [MAC]; size No. Orotracheal intu- bation should be done only with great care in cases of suspected cervical spine injuries. Any patient who is hypoxic or apneic must be ventilated prior to attempting endotra- cheal intubation (bag mask or mouth to mask). Remember to avoid prolonged periods of no ventilation if the intubation is difficult. When you need to take a breath, so must the patient, and you should resume ventilation, and reattempt intubation in a minute or so. Extend the laryngoscope blade to 90 degrees to verify the light is working, and check the balloon on the tube (if present) for leaks. If the straight laryngoscope blade is used, pass it under the epiglottis and lift upward to visualize the vocal cords (Fig. If the curved blade is used, place it anterior to the epiglottis (into the vallecula) and gently lift anteriorly. In either case, do not use the handle to pry the epiglottis open, but rather gently lift to expose the vocal cords. While maintaining visualization of the cords, grasp the tube in your right hand and pass it through the cords.
