Optimal retention time of patient-controlled intravenous analgesia after robot-assisted laparoscopic radical prostatectomy

  Objective  To explore the optimal retention time of patient-controlled intravenous analgesia (PCIA) pump after robot-assisted laparoscopic radical prostatectomy.

  Methods  A total of 101 patients receiving the 4^th generation Da Vinci robot assisted laparoscopic radical prostatectomy (RLRP) were selected and divided into control group (n=49) and observation group (n=52).The PCIA pump was kept for 24 h in the observation group and 48 h in the control group.The cases with dizziness symptoms at the first time of bed-off activity after operation,the cases with successful postoperative activity at 24 h,scores of pain at 24,48 and 72 h,the cases with additional analgesics within 72 hours after surgery,and the average postoperative hospital stay were compared between the two groups.

  Results  There were significant differences in the cases with dizziness after oepration and successful bed-off activity between the two groups (P < 0.05).There were no significant difference in pain scores at 24,48 and 72 hours after operation between the two groups (P>0.05).There was no significant difference in the cases with additional analgesics within 72 hours after operation between the two groups (P>0.05).The average postoperative hospital stay was (5.2±0.8) days in the observation group,which was significantly shorter than (6.9±1.0) days in the control group (P < 0.05).

  Conclusion  The optimal retention time of PCIA after RLRP is 24 h.Shortening the unnecessary indwelling time after operation can reduce the occurrence of dizziness caused by analgesics,and is conducive to the successful early bed-off activity of patients.
