The haemodynamic responses to tracheal extubation at the end of surgery were compared with those occurring at tracheal intubation in 12 patients undergoing major elective surgery. Arterial cannulation was performed and heart rate (HR), systolic arterial pressure (SAP) and diastolic arterial pressure (DAP) were measured before induction of anaesthesia, before tracheal intubation, at the end of surgery and 1, 3 and 5 min after tracheal extubation. Laryngoscopy was avoided at the end of surgery. ⋯ Rate-pressure product (RPP) was derived from SAP x HR. After tracheal intubation there were significant (P less than 0.05) increases in HR, DAP, RPP and in plasma concentrations of both adrenaline and noradrenaline. After extubation, only HR and adrenaline concentration at 5 min after extubation increased significantly compared with measurements at the end of surgery.

A 5-year retrospective review of airway management by flight nurses was conducted to evaluate airway care and to determine the frequency of surgical cricothyrotomy. Intubation was attempted in 51% of patients, with a success rate of 80%. ⋯ Overall, 87% of patients were successfully intubated and surgical cricothyrotomy was required in only one patient. A greater success rate was achieved when intubations were performed before takeoff than during flight.

[Selective right bronchial intubation using tracheal tubes under fibroscopic guidance].
We have evaluated the technique of right bronchial intubation for selective right pulmonary ventilation using one lumen tracheal tubes as an alternative to double lumen tubes. We studied 20 patients ASA II-III with a relatively preserved pulmonary function who were programmed for left thoracotomy. We used Shiley nr. 9 or Mallinckrodt nr. 11 tubes. ⋯ In three patients (15%) blinded placement of the tube was appropriate and in 4 patients (20%) fibroscopic replacement of the tube was required. In the remaining 13 patients (65%) placement of the tracheal tube was considered incorrect: tube rotation in 7 cases, upper placement of the Murphy's hole with respect to the origin of the superior lobar bronchus in 4 cases, and excessive distal placement of Murphy's hole with respect to the superior lobar bronchus in 2 patients. Complications related with the incorrect position of the tube were: leaking of gas into the left bronchium in 5 patients (25%), displacement of the tracheal tube into the main left bronchus requiring withdrawal of the tube to the trachea in one case (5%), hypoxemia (saturation of O2 lower than 90%) in spite of ventilation with FiO2 = 1 in two patients, moderate hypercapnia in three cases, and atelectasis of the right superior lobe during the postoperative phase in three patients (15%).(ABSTRACT TRUNCATED AT 250 WORDS)
