摘要:

The authors determined the hemodynamic effects of pancuronium bromide in chronically instrumented adult beagle dogs. Pancuronium bromide (0.12 mg/kg) significantly increased heart rate. There was no statistically significant change of systemic arterial, right atrial or left atrial blood pressure, cardiac output, stroke volume, or renal blood flow. The hemodynamic effects of pancuronium bromide are limited and probably not detrimental to cardiovascular function.

摘要:

The influence of various factors on left bronchial tree suctioning was assessed using suction catheters containing a radiopaque wire marker. In the control group, the left bronchial tree was entered in 33% of attempts through endotracheal tubes and 29% of attempts through tracheostomy tubes. Manipulation of either the trachea or the tracheostomy tube did not increase left bronchial entry. A curved-tip catheter significantly improved left bronchial entrance rate when passed through tracheostomy tubes (p< 0.05), but not when passed through endotracheal tubes.

摘要:

Broadening indications for continuous monitoring of intracranial pressure (ICP) in neonates and small infants have created increasing interest in modalities which would permit measurement of ICP safely and accurately. Such monitoring allows rapid initiation of treatment when increased ICP is observed. Using a new technique for subdural tap, the authors inserted percutaneously a subdural catheter in 9 patients, 5 had cerebral ischemia, and 4 had CNS infection. These patients exhibited marked changes in ICP during the course of their disease, often within a short time period. Continuous monitoring made it possible to initiate treatment immediately at the onset of increased ICP. In this series, no complication related to the subdural catheter placement was observed. This technique proved to be highly accurate, effective, safe, and very easy to perform.

摘要:

A newly designed hygroscopic condenser humidifier was evaluated to assess efficacy of providing moisture to the airways in patients whose upper airways had been bypassed. With its use, the relative humidity of inspired gas fell with both increasing tidal volumes and especially increasing FIO2due to the intrinsic dryness of medical oxygen. Under conditions other than high volumes and inspired oxygen, humidification appeared adequate. The device obviated many complications encountered with conventional heated nebulizers. It does add some degree of resistance in the ventilatory circuit which might be stressful during spontaneous breathing.

摘要:

The NL-tracheostomy tube has a large diameter, large residual volume cuff with automatic and instant cuff pressure regulation. It has been shown in clinical studies to prevent mucosal damage; and depending on airway pressure, it should in theory prevent or delay the onset of tracheal dilatation. The authors report 2 patients who developed severe tracheal dilatation with use of standard low volume cuffs during prolonged mechanical ventilation. Placement of the NL-tracheostomy tube with a special long intratracheal leg and cuff positioned below the dilatation abolished the acute problems of air leakage. Tracheal dilatation at the new cuff site did not develop in 1 patient and was slowed in onset in the 2nd patient, who needed high inflation pressures.

摘要:

Difficulty in balloon deflation of urinary balloon catheters is often encountered. In this experimental study, distilled water and three kinds of organic solvents (ether, chloroform and toluene) were injected in 72 Rüschs' balloon catheters of 4% silicon-rubber. The ether method, which is widely accepted, often leaves a broken piece of the balloon in the bladder. It was found that toluene is far safer and superior to ether for breaking the balloon of the urinary catheter.

摘要:

A case is presented of a patient with ascites who, with insertion of a peritoneovenous shunt, developed recurrent ventricular tachycardia unresponsive to antiarrhythmic medications due to displacement of the intracardiac portion of the shunt.
