Randomized Controlled Trial Comparative Study[A study of mechanical ventilation pattern in different recovery stages of muscle relaxant after general anesthesia].
To observe the effects of intermittent positive pressure ventilation (IPPV), synchronized intermittent mandatory ventilation (SIMV), and biphasic intermittent positive airway pressure (BiPAP) on the recovery time of automatic breathing in patients in different stages of recovery of general anesthesia with muscle relaxant. ⋯ SIMV and BiPAP have the advantages as follows: no confrontation between mechanical ventilation and autonomous breathing, quick recovery of autonomous breathing, little change in airway pressure, high MV and low P(Et)CO(2). So SIMV and BiPAP are more suitable for recovery from anesthesia. In addition, BiPAP can lower the airway's peak pressure and decrease the probability of barotrauma therefore it is more suitable for those patients with high airway pressure.
