Tracheal intubation may be hindered by difficulty in insertion of the laryngoscope blade into the patient's mouth because the handle impinges on the patient's chest or on the hand of an assistant applying cricoid pressure. An adaptor is described which modifies the standard Penlon laryngoscope to enable lateral swivelling of the handle, thus avoiding the obstruction.

The adequacy of initial ventilation in 21 preterm babies (25-36 weeks' gestation), who required endotracheal intubation and positive pressure ventilation, were studied. Pressure and flow were measured at the proximal end of the endotracheal intubation tube and expiratory volume calculated from the flow trace. The results were compared with those from a group of 26 term infants who also required resuscitation. ⋯ Respiratory reflex responses to resuscitation were seen in 41% of inflations in preterm and 56% of inflations in term infants. There was a significant correlation between reflex activity and adequate ventilation in the preterm group (chi 2 = 11.83, p less than 0.001) but not in the term group (chi 2 = 0.212, p = NS). No correlation was seen between initial ventilation and outcome.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of blind nasotracheal and succinylcholine-assisted intubation in the poisoned patient.
In the patient obtunded by drug intoxication, the optimal method of airway protection prior to gastric emptying is not clear. We report a prospective randomized trial of two methods of intubation in this patient population. Fifty-two overdose patients with Glascow Coma Scale scores of 12 or less were intubated either orotracheally after succinylcholine administration or nasotracheally. ⋯ Sixty-nine percent of the BNI group experienced epistaxis, 17% had vomiting, and 10% aspirated. We conclude that SAI is a safe and effective method of airway protection in the obtunded poisoned patient. Complications and difficulty in intubation were significantly less with SAI than with blind nasotracheal intubation.
