An inspired-air heating and humidifying device was constructed and evaluated with regard to its ability to maintain mean body heat in anesthetized cats. Control cats exhibited a net heat loss of -5.960 and -2.970 Kcal for each of 2 successive hours. ⋯ The inspired-air heating and humidifying technique was associated with a significantly slower decrease in body temperature (P less than 0.05) after 45 minutes. The inspired-air heating technique is beneficial in minimizing body heat loss during general anesthesia in cats, but is not effective enough to supplant other methods.

Randomized Controlled Trial Comparative Study Clinical Trial
Anaesthesia for transurethral prostatectomy. A comparison of spinal intradural analgesia with two methods of general anaesthesia.
One hundred and fifty patients who presented for transurethral prostatectomy were randomly allocated to one of three groups for the purpose of anaesthesia. Group A received spinal intradural analgesia, Group B general anaesthesia with spontaneous ventilation and Group C general anaesthesia with controlled ventilation. The comparability of the three groups was established. ⋯ Dysrhythmias were significantly higher in Group B. The results support the conclusion that the methods of choice for anaesthesia for transurethral prostatectomy are spinal analgesia or general anaesthesia using muscle relaxants and controlled ventilation. The final decision is a matter of personal preference.

Randomized Controlled Trial Comparative Study Clinical TrialEpidural versus general anaesthesia for total hip arthroplasty in elderly patients.
Sixty elderly patients were given at random either epidural analgesia with bupivacaine 0.75% or general anaesthesia with thiopentone, fentanyl, pancuronium, N2O/O2 for total hip replacement. Preoperatively the patients were of equal physical status with normal and similar laboratory values. All patients were mentally normal for their age. ⋯ Two patients in the epidural group had symptoms of pulmonary embolism postoperatively. Thus elderly patients appear to do better after hip replacement with less deterioration of cerebral and pulmonary functions when given epidural analgesia than when surgery is performed under general anaesthesia. These patients should therefore be offered epidural analgesia whenever possible.
