Periparturient and neonatal anesthesia

摘要

Patients presented in the periparturient period may need surgery for nonobstetric reasons, they may be undergoing hysterectomy, they may be undergoing an elective cesarean section, or they may need an emergency cesarean section. In all these circumstances, it is important to recognize that the dam has undergone some physiologic changes during pregnancy that alter the response to anesthesia. In addition, the clinician must consider the fate of the neonates and be able to optimize the anesthetic technique for their welfare. Extensive human data have been published on the action of and outcome from anesthesia; however, because of species and technical differences, veterinarians may not be able to directly apply the knowledge gained from human obstetric experiences. For the veterinarian, many review articles have been published,(6) (12, 24, 32, 35, 39, 49, 57, 69) but there are few data that support the use of one technique over another.(31, 56) This has resulted in tremendous variation in the perioperative management of such cases and a continued search for the "best technique."
