[Effects of intravenous injections of lidocaine on hemodynamics and catecholamine levels during endotracheal intubation in infants and children].
It is known that during anesthesia, administering medication and endotracheal intubation often cause stress for the patient which induces sthenia of the endocrinal system as well as changes in hemodynamics, sometimes leading to further systemic complications. Various changes in hemodynamics caused by endotracheal intubation in infants and children were studied, including tachycardia and increased blood pressure. Changes in catecholamine levels in blood plasma and in cardiovascular parameters were observed, with patients divided into two groups for comparison. ⋯ The results also indicate that systemic complications during the induction of general anesthesia may be due to an increased secretion of endogenous catecholamines. These results further suggest that an intravenous injection of lidocaine is not effective in suppressing the increase of catecholamines in the plasma during endotracheal intubation. The intravenous injection of lidocaine, however, inhibits tachycardia and also inhibits the increase in blood pressure often caused by endotracheal intubation, and also serves to reduce the general oxygen demand in the cardiac tissue.

Randomized Controlled Trial Clinical Trial Controlled Clinical Trial
The oesophageal detector device. A prospective trial on 100 patients.
Misplacement of a tracheal tube in the oesophagus remains a significant cause of mortality and morbidity in anaesthesia, despite decades of effort aimed at prevention, or perhaps more importantly, detection, of such an event. We have evaluated a cheap, simple and quick device which relies mainly on the reflation or otherwise of an Ellick's evacuator applied to the supposed 'tracheal' tube. ⋯ There were no false positive results and the correct deduction of which was the tracheal tube was reached in 100 tests using this device. Its use is recommended for widespread evaluation as a valuable adjunct to existing methods of detecting misplacement.

We evaluated the use of an inexpensive trans-illuminating light wand for tracheal intubation. Expertise in its use was acquired quickly, thereby providing successful per-oral intubation in all patients who were able to open the mouth, irrespective of the view obtained of the epiglottis and larynx.

Randomized Controlled Trial Clinical Trial
Effect of buprenorphine on the cardiovascular response to tracheal intubation.
The effects of buprenorphine on the haemodynamic responses to tracheal intubation were studied in a placebo-controlled double-blind trial in 40 patients who had elective surgery. In one group saline was administered intravenously 8 minutes before induction, whereas the others received buprenorphine 2.5 micrograms/kg intravenously. ⋯ In the buprenorphine group, the maximum increase in systolic and diastolic arterial blood pressures, heart rate and rate pressure product were significantly lower compared to the control group. It is concluded that buprenorphine is partially effective in attenuating the cardiovascular response to laryngoscopy and intubation, but does not obliterate it.

A newly designed nasal bridle and rationale for its clinical use are described. Previous nasal bridles have been shown to reduce the 40 to 60% incidence of dislodgement of nasoenteral feeding tubes. ⋯ The newly designed nasal bridle described herein has the advantages of easy and rapid placement. Use of this bridle can promote safer and more effective enteral feeding while avoiding the complications and cost of parenteral nutritional and gastrostomies.
