Case Reports[Tooth injuries during general anesthesia, oral endoscopy and vibro-massage].
It is generally recognized that dental injury during and after tracheal intubation is a significant problem. Damage may occur during oro-tracheal intubation, oral endoscopy or seismotherapy. The incidence was reported in a study conducted in the contentious department of Lyon hospitals, in France, from 1978 to 1988. ⋯ Some of the most recent development in dental therapy such as the butterfly bridge, titanium implants and porcelain laminate veneers are described. Tooth protective guards must be put into widespread use. Legal implications of dental lesions occurring during oro-tracheal intubation, oral endoscopy or seismotherapy are presented.

The effect of position, horizontal versus 5 degrees reverse Trendelenburg's, on the incidence of venous emboli during Caesarean section was evaluated in 207 patients. Venous emboli were diagnosed using precordial ultrasonic Doppler monitoring. In the horizontal position, 44% (60 of 134) parturients had venous emboli compared with 1% (1 of 73) parturients in the 5 degrees reverse Trendelenburg's position (P less than 0.0001). ⋯ In the epidural group, pulse oximetric haemoglobin oxygen desaturation and complaints of chest pain and/or dyspnoea were associated with the venous emboli. Venous emboli, probably air, occur frequently during Caesarean section with the patient in the horizontal position. This occurrence was minimized by placing the patient in the 5 degrees reverse Trendelenburg's position.

Malpractice claims filed against anesthesiologists for care involving obstetric (OB) anesthesia (n = 190) were taken from the American Society of Anesthesiologists' Closed Claims Database and compared to claims not involving OB cases (n = 1351). The most common complications in the OB claims were (percentage of all OB claims): maternal death (22%), newborn brain damage (20%), and headache (12%). In contrast, the most common complications in the nonobstetric (non-OB) group were (percentage of all non-OB claims): death (39%), nerve damage (16%), and brain damage (13%). ⋯ Claims involving general anesthesia were more frequently associated with severe injuries and resulted in higher payments than did claims involving regional anesthesia. Payments were made in a similar proportion of OB and non-OB claims (53 and 59%, respectively). For cases in which payments were made, the median payment for OB claims was significantly greater ($203,000) than for non-OB claims ($85,000; P less than or equal to 0.05).

Conventional lateral radiography was used in 18 elderly male patients to investigate the changes induced by general anaesthesia in the upper airway. The effect of tongue traction under anaesthesia was studied similarly in another 11 patients. ⋯ Traction on the tongue failed to clear the nasopharyngeal obstruction. Attempted inspiration under anaesthesia caused major secondary collapse of the pharynx, with multiple sites of obstruction, similar to that found in obstructive sleep apnoea.

Case Reports
[An emergency cesarean section using general anesthesia for a patient with schizophrenia].
A 27 year-old female in 39th week gestation with schizophrenia underwent an emergency Cesarean section using general anesthesia. A diagnosis of schizophrenia was made two years previously, since then oral anti-psychotic drugs such as chlorpromazine had been given to her. In June 1989 she suddenly became excited and generalized muscle rigidity was observed without any triggering episodes. ⋯ The baby's Apgar score was 9 and 1 min and 9 at 5 min after the delivery. The baby developed slight generalized tremor until next day, probably due to effect of levomepromazine given before the Cesarean section. The patient was discharged without any cardiorespiratory trouble and her baby has been doing well so far.
