Historical ArticleAnesthetic management. Historical, present, future.
This article deals with specific agents that either have been or are being employed for the production of general anesthesia or sedative states for the control of pain or anxiety in the dental setting. Change, progress, trends, and contributions to the field of dental anesthesia made by dentists are stressed. In addition, a brief synopsis of the most popular present-day techniques and agents is discussed. Finally, the future of the field of dental anesthesia and the role to be played by dentists is considered.

Postanesthetic complications can occur even in the best of circumstances. Proper preparation of the staff, aggressive monitoring of the recovering patient, and early recognition and management of the complications are essential if the outcome is to be successful. ⋯ The anesthetic procedure is not over once the anesthetic agents are discontinued. The skillful anesthetist is aware of the possibilities of postoperative complications and prevents problems by employing enhanced monitoring techniques during the recovery phase.

Intraoperative anesthetic complications can be prevented or minimized if the anesthetist is able to anticipate such problems in the preanesthetic period. Therefore, an adequate preanesthetic medical history that includes previous anesthetic experiences and past and current drug therapy is extremely important. ⋯ The signs of an impending disaster are subtle and nonspecific in the anesthetized patient. Therefore, continuous vigilance of the patient's physiologic status coupled with a high index of suspicion are essential to safe anesthetic management of dental patients.

The value of maternal and fetal blood gas analysis in cesarean sections under general anesthesia.
Maternal and fetal blood gas values were studied in 90 selected mothers of comparable age, weight, duration of pregnancy and hematocrit values undergoing cesarean section under balanced general anesthesia in four differing clinical situations: elective with and without placental dysfunction, and emergency with and without fetal distress in apparently normal mothers. Pre-induction (Fi O2 0.21) and pre-delivery (Fi O2 0.60) maternal blood gas analysis, along with umbilical cord blood gas analysis were performed in all cases. ⋯ Of the remaining 54 cases (60%) with similar mean maternal gas values the neonates showed an apgar score of less than seven in the first minute. The score improved in three minutes in 35 of them (66%), and umbilical cord blood gas values showed a low pH (umbilical vein 7.22 +/- 0.02 units, umbilical arterial 7.21 +/- 0.01 units) but satisfactory pO2 (umbilical vein 39.4 +/- 1.9 torr, umbilical arterial 2.5 +/- 1.3 torr).(ABSTRACT TRUNCATED AT 250 WORDS)
