Clinical studies about patients with laryngeal mask airway of laparoscopy total hysterectomy / 中国基层医药

ABSTRACT

Objective To observe the sedation and analgesia in surface anesthesia in conscious glossopha-ryngeal LMA for the clinical effect of laparoscopic hysterectomy.Methods 90 patients undergoing elective laparo-scopic total hysterectomy were randomly divided into three groups,30 cases in each group.The observation group (group A)sedation,analgesia,full surface anesthesia,control group 1 (B group)control group 2 (group C)were treated with endotracheal intubation under general anesthesia.At intubation and pull tube stage,the patients'reaction, hemodynamic changes,pneumoperitoneum 1 h blood gas and perioperative complications were observed.Results The mean arterial pressure(MAP)and heart rate(HR)of A group were (92.7 ±10.6)mmHg and (82.8 ±12.1)/min. Those of B group were (98.4 ±11.6)mmHg,(89.1 ±11.4)/min,C group were (111.2 ±12.5)mmHg,(104.1 ± 13.2)/min,those in A group and B group were better than C group(A group and C group,t =6.18,6.52,P <0.01;B group and C group,t =4.11,4.71,all P <0.01).The pulse oxygen saturation(SpO2 )and peak airway pressure (Paw)of A group were (99.6 ±0.4)and (17.3 ±2.1)mmHg,those in group B were (99.5 ±0.5)% and (17.6 ± 2.0)mmHg,group C were (99.5 ±0.5)% and (22.5 ±2.8)mmHg.The differences between A group and B group were statistically significant(compared with C group,t =14.3,8.14,all P <0.01;B group and C group,t =12.7, 7.78,all P <0.01).The incidence rates of perioperative complications and adverse reactions of A,B,C groups were 27%,33%,67%,that in C group was significantly higher than A group and B group(χ2 =9.64,6.67,all P <0.01). Conclusion The laryngeal mask airway was used for laparoscopic total hysterectomy under the condition of sedation and analgesia,and it can shorten the time of the whole body,prevent the difficulty of intubation,emergency airway and anesthesia related complications.
