Application and efficacy evaluation of an NBASS-APS pain management model in postoperative analgesia for gastric cancer patients.

PURPOSE: Postoperative pain is a complex physiological and psychological response caused by noxious stimulation and almost occurs in every patient. The purpose of this study was to investigate the outcome of an NBASS-APS pain management model, which refers to nurse-based, anaesthesiologist and specialist-supervised (NBASS) acute pain services (APS), in postoperative analgesia for gastric cancer patients.

METHODS

228 patients were included and were randomly divided into an observation group of 113 individuals and a control group of 115 individuals. The observation group subjects were provided with an NBASS-APS pain management model; the control group subjects were provided with customary APS (C-APS), which included postoperative analgesia services managed by pain care nurses and physicians. In addition, a comparative study was performed to examine the postoperative analgesic outcome, postoperative recovery of physiological function, and the patient satisfaction levels of the two groups.

RESULTS

The observation group had significantly lower values for the postoperative visual analogue score (VAS) after return to the ward compared with those in the control group (p<0.05), the postoperative VAS mean, duration of the maximal VAS value, and duration of the VAS value >3 than those in the control group (p<0.05), and the patients in the observation group exhibited the same effect in the first ambulation time and postoperative hospital stay (p<0.05). The observation group had a significantly greater sleep duration within the first postoperative 48 hrs (p<0.05), and also showed a significantly greater score in the satisfaction level for the postoperative analgesic effect (p<0.05).

CONCLUSION

These findings suggest that the NBASS-APS pain management model effectively reduced the postoperative pain of gastric cancer patients, benefited their recovery of physiological functions, and improved their satisfaction with the postoperative analgesic effect.
