Conscious awareness is an infrequent complication of general anesthesia. All methods of anesthesia have been implicated, and no method guarantees amnesia. This article examines implicit and explicit memory and discusses factors associated with awareness. ⋯ Strategies to block threatening auditory stimuli include use of earphones, music tapes, white noise, reassuring statements, or positive suggestion. Behavioral anesthesia decreases patient stress to enhance recovery. Evidence of patient benefit resulting from therapeutic suggestion is inconclusive.

Twelve cases of post-anaesthetic pulmonary oedema (PO) secondary to upper airway obstruction (UAO) are reported. All were adult male patients undergoing uneventful elective surgical procedure under general anaesthesia. Post-anaesthetic laryngospasm was the single most important factor for the upper airway obstruction (UAO) in 5 (41.6%) patients. ⋯ Early recognition, maintenance of patent airway and adequate oxygenation via face mask or endotracheal tube with mechanical ventilation resolved the syndrome within 6-36 hours in all of these patients. Invasive haemodynamic monitoring or aggressive drug therapy were not applied in any of the patients. A heightened awareness among anaesthesiologists of the varied causes of post-anaesthetic UAO leading to PO may help reduce the occurrence and facilitate early management of the potential complications.

Blood pressure measurement using oscillometric finger cuffs in children and young adults. A comparison with arm cuffs during general anaesthesia.
Arterial blood pressure measurements (y) obtained from forefinger cuffs were compared with standard arm cuff readings (x) in 41 anaesthetised children and young adults. Mean (SD) differences between cuff measurements were -0.21 (9.15), -1.56 (10.2) and 1.23 (9.12) mmHg for the systolic, mean and diastolic pressures respectively. The correlation for systolic blood pressures (r = 0.85, y = 0.99x + 0.58, sy.x = 9.15) was better than that for mean or diastolic pressures. Oscillometric finger cuffs are suitable for monitoring the systolic blood pressure in children and young adults during general anaesthesia.
