Abstract:

Objective To evaluate the factors influencing the quality of anesthesia recovery after robot assisted laparoscopic radical prostatectomy. Methods Sixty patients having undergone radical prostatectomy were divided into two groups：L Group（operation time ≤ 2 h）and S group（operation time > 2 h）. The degree of anes⁃ thesia in both groups was assessed after extubation in the postanesthesia care unit（PACU）. The time of awake extu⁃ bation，time of discharge out of PACU，scores by visual analogue scale（VAS）and frequency of nausea and vomit⁃ ing were recorded and analyzed to look into the correlations of the influencing factors of anesthesia recovery quality with the operation duration，age，body mass index（BMI）. Results The awake extubation time ofthe S groupwas shorter than that of the L group（P < 0.05），and the time of discharge out of PACU in the S group was shorter than that of the L group（P < 0.01）. The awake extubation time was significantly correlated with the operation duration， time of discharge out of PACU and age（P < 0.01），but insignificantly with VAS and BMI（P > 0.05）. Conclusion The robot assisted minimally invasive surgery is optional for patients with prostate cancer upon the characteristics of patients and the experience of surgeons. Before operation，it is suggested to predict those influencing factors such as operation time and age and even make precautious measures for those patients with high risks so as to promote their rehabilitation and reduce the incidences of complications.
