General anesthesia is provided in the dental office primarily to reduce fear, block pain, produce amnesia, and provide a more comfortable surgical environment. Because the perception of pain is a major obstacle to the obtainment of dental health in the United States, general anesthesia has become an essential part of the practice of dentistry. It benefits both the patient and the surgeon to make dentistry a pleasant, painless experience.

Randomized Controlled Trial Clinical Trial
Minor complications following anaesthesia in young adults for orthopaedic surgery of the lower extremity.
In all, 175 young (15-40 yr) patients received either spinal anaesthesia with bupivacaine (104 patients) or general, balanced anaesthesia (71 patients) for orthopaedic surgery of the lower extremities. Each patient was interviewed before the operation, problems that arose during the operation were recorded and all patients were interviewed on the first postoperative day. One hundred and seven patients were interviewed after being discharged, 1-3 months after the operation. ⋯ All these problems had ceased at the interview 1-3 months later. Eight (six spinal and two general anaesthesia patients) were not satisfied with the method of anaesthesia used. This study revealed that an appreciable number of young patients have complications after anaesthesia, but the complications are minor and self-limited.

Review Comparative StudyNeuro-anaesthesia: the present position.
Over the years the basic principles underlying the practice of neuroanaesthesia have not changed, but introduction of new anaesthetic agents and associated techniques have improved the ability of the neuroanaesthetist to "fine tune" the patients physiological state. This has improved the capacity of the neuroanaesthetist to mitigate the inevitable fluctuations which occur and prevent their ill effects. ⋯ It takes years for the correct plan of usage of new drugs to be formulated for the clinical situation, and their relationships established to new techniques of patient monitoring. Like neurosurgery itself neuroanaesthesia shows no signs of approaching a final definitive state in the forseeable future.

Use of capnography and transcutaneous oxygen monitoring during outpatient general anesthesia for oral surgery.
The combination of the capnograph (respired CO2 monitor) and the transcutaneous oxygen monitor was evaluated as a non-invasive system for monitoring of respiratory function in 10 ASA class I patients undergoing ultralight general anesthesia for removal of third molars. Capnography proved to be a sensitive and accurate method for detecting apnea and airway obstruction using the continuous display of the CO2 waveform. All episodes of apnea or obstruction were immediately detected as the respired CO2 level fell to zero baseline. ⋯ During steady-state conditions of respiration, transcutaneous oxygen tensions (PtcO2) correlated well with simultaneously measured PaO2 (r = 0.93). However, during any period when oxygenation was rapidly changing (step increase in FIO2, step decrease in FIO2, or apnea) the PtcO2 lagged behind changes in PaO2 even after a five-minute equilibration period, thereby not accurately reflecting the true state of oxygenation. Consequently, the transcutaneous oxygen monitor does not appear to be optimal as a respiratory monitor in the setting of ultralight general anesthesia where rapid, critical changes in oxygenation must be detected without delay.

The case histories of two patients who required the insertion of intratracheal stents are presented. The peroperative anaesthetic management of one case included the use of high frequency jet ventilation of the lungs; in the other case, partial cardiopulmonary bypass was used. The advantages and disadvantages of these two methods are discussed.
