Objective To compare the impact of patient controlled epidural analgesia with patient controlled intravenous analgesia on postoperative recovery and complications in patients undergoing laparotomy pancreatic surgeries.Methods Forty patients undergoing pancreatic surgeries, 27 males and 13 females, aged 18-70 years, ASA physical status Ⅰ or Ⅱ, were randomly divided into two groups (n=20 each).Patients in group E received T8-9 or T9-10 epidural block, 2% lidocaine test dose was given to ensure the location of epidural catheter, after that, each patient in group E was given 0.375% ropivacaine 5 ml into epidural space before skin incising and incision closures.Meanwhile, patients in groups E and V received propofol-sevoflurane combined intravenous inhalation anesthesia.After surgery, patients in group E received patient controlled epidural analgesia while patients in group V received patient controlled vein analgesia.Length of hospital stay, time to ambulation and exhaust defecation were recorded.Other complications were compared.Results Compared to group V, patients in group E showed earlier ambulation [(50.4±4.2) h vs (64.2±5.0) h, P<0.01], shorter hospital stays [(18.5±8.5) d vs (21.5±6.8) d, P<0.05].There was no statistically significant difference in flatus time between the two groups [(39.7±4.1) h vs (39.5±8.4) h].There was no significant difference in complications between the two groups.Conclusion The present study shows that for patients undergoing pancreatic surgeries, patient controlled epidural analgesia could effectively release post-operative pain, shorten the ambulation time and length of hospital stay with no extra complications.

By examining the records related to the Fengfu （GV 16） acupoint in BIAN Que Heart Book （《扁鹊心书》） compiled by the Song Dynasty physician DOU Cai， this study analyzed various aspects， including the differentiation of conditions treated with Fengfu （GV 16） acupoint， the theoretical foundation for selection of Fengfu （GV 16） acupoint， the application of needling manipulation， and the sensation of obtaining qi during acupuncture. The findings suggest that DOU Cai's approach to utilizing Fengfu （GV 16） acupoint differs from traditional methods， particularly emphasizing the effectiveness of achieving a sensation of heat and numbness. His unique techniques include transverse insertion at Fengfu （GV 16） acupoint and penetrated insertion to Fengchi （GB 20） and Yifeng （TE 17） acupoints. The records of Fengfu （GV 16） acupoint in BIAN Que Heart Book provide a valuable reference for its modern clinical application and further development.
