The Intermittent Pneumoperitoneum Scheme of Work Breaks in Complex Laparoscopic Surgery (IPP)

Abstract

Background: Work breaks at close intervals are common in fields with high workload but not yet for medical operators. We evaluated the effects of intraoperative breaks (five minutes every half hour) on the surgeon and on the patient.

Methods: Operations were randomized to either a scheme with intraoperative breaks and release of the pneumoperitoneum (intermittent pneumoperitoneum = IPP) or a conventional conduct (CPP). Stress hormones and α-amylase were determined in the surgeon's saliva pre-, intra- and postoperatively. Mental performance and error scores, musculoskeletal strain and continuous ECG were secondary endpoints. The children's physiology was monitored.

Findings:

Regular intraoperative breaks did not prolong the operation. The surgeon's cortisol levels during the operation were reduced. There were fewer intraoperative events in the IPP vs. the CPP group. The pre- to postoperative increase in the error rates of the bp-concentration test was reduced in the IPP group. The relevant locomotive strain-scores were reduced by IPP.

There was no negative impact on the patient. Interpretation: Our data support the idea that work breaks during complex laparoscopic surgery can reduce psychological stress and preserve performance with at least similar patient outcome compared to the traditional work scheme.
