Case ReportsCricoarytenoid subluxation, computed tomography, and electromyography findings.
A case of cricoarytenoid subluxation secondary to endotracheal intubation and documented by computed tomography (CT) and electromyography (EMG) is reported. Successful endoscopic reduction of the displaced arytenoid is confirmed by CT. The normal anatomy and physiology of the cricoarytenoid joint is presented and the literature regarding this rarely reported injury is reviewed. Based on this review and the case reported, a treatment plan is proposed.

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.
