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.

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.

Paramedics intubated 358 of 383 (93.5%) patients over a nine-month period. There were 85 survivors. The intubators used the curved-blade laryngoscope in 304 patients (79.5%). ⋯ This retrospective study further documents the ability of paramedics to successfully perform endotracheal intubation. The high success rate supports training with live subjects. Further studies of cause and impact of complications, correlation of success with increased survival, and alternative techniques are essential for effective EMS system medical control.
