Randomized Controlled Trial Clinical Trial
Post-operative sore throat: effect of lignocaine jelly and spray with endotracheal intubation.
The effects of laryngeal lignocaine spray and/or lignocaine jelly as lubricants were studied on the incidence of sore throat, hoarseness, or tracheal irritability as evidenced by either a tendency to cough or frank coughing after intubation with a Sensiv tube (Searle Medical Products). Pressure in the medium-volume, low-pressure cuff was controlled and kept below 2.5 kPa (25 cmH2O) during anaesthesia. The side-effects of 94 surgical patients were recorded in a double-blind manner in the recovery room and on the first post-operative day. ⋯ In 42% of the patients receiving N2O a limiting value of 2.5 kPa (25 cmH2O) was reached during anesthesia in a mean time of 74 min (range 25-180 min). After the replacement of N2O with nitrogen, the cuff pressure decreased from 1.8 kPa (18 cmH2O) to 0.7 kPa (7 cmH2O) over 40 min. It is concluded that lignocaine jelly with the use of a spray significantly increases post-operative side-effects.

Randomized Controlled Trial Comparative Study Clinical TrialQT interval of the ECG, heart rate and arterial pressure using five non-depolarizing muscle relaxants for intubation.
The QT interval, heart rate and arterial pressure were measured during anaesthetic induction in 186 patients without cardiovascular diseases or any preoperative drugs. The study was randomized and double-blind. The patients were premedicated with either pethidine 1 mg/kg + atropine 0.01 mg/kg or with only pethidine 1 mg/kg i.m. ⋯ The QT intervals were prolonged only in relation to the increased heart rate. At 6.5 min, the values in all groups were decreased to about the same level as before intubation. The mean control values of the heart rate were between 80 and 90 b.p.m. in the atropine-treated groups and between 70 and 80 b.p.m. in the other groups.(ABSTRACT TRUNCATED AT 250 WORDS)

The esophageal obturator airway has been in use for the past 20 years. It is promoted as being easy to use and can be rapidly inserted blindly; however, numerous complications have been noted. The device is reviewed in this article and compared to endotracheal intubation.

ReviewPharmacologic aids to intubation and the rapid sequence induction.
Endotracheal intubation usually can be performed in the emergency setting without the use of pharmacologic adjuncts. However, local airway anesthesia lessens patient discomfort, and the use of sedation and muscle relaxants occasionally may be necessary. Rapid sequence induction of general anesthesia adds benefits as well as risks to airway management; used in the circumstance of a full stomach combined with open eye injury or closed head injury associated with raised intracranial pressure, it should be practiced only by physicians appropriately trained and skilled at the procedure.
