INTRODUCTION: We recently reported that 5-minute work breaks every 25 minutes during long lasting laparoscopy in children (intermittent pneumoperitoneum [IPP] scheme) decrease the surgeon's stress markers such as saliva cortisol and heart rate and improve time-concentration scores significantly. Data on the impact of breaks on the patient and on the surgeon's perception of breaks, however, are still lacking. MATERIALS AND METHODS: We present the comprehensive biometry data of a randomized trial including 26 patients operated with (IPP) and 26 patients without breaks (continuous pneumoperitoneum [CPP]). Moreover, we analyzed the surgeon's perception of the break scheme using behaviorally anchored 10-point rating scales. RESULTS: There were no significant intergroup differences in the pooled patients' hemodynamics including cardiac output, blood gas readings, and temperature during and after the operation. Infants <1 year of age undergoing IPP versus CPP produced significantly higher urine volumes (1.60 ± 1.8 vs. 0.67 ± 1.00 mL/h/m2, p < 0.05). The overall area under the curve (AUC) of their cardiac output was 106.7 ± 41.1 (IPP) versus 78.0 ± 41.3 (CPP). This difference became significant during long operations (p < 0.05 for AUC 150 to 270 minutes). Surgeon's break perception and acceptance: team communication shifted from an implicit "mute communication" to an explicit way "issues are outspoken" by +4.7 ± 2.6 (p < 0.05) with improved coherence between operator and assistants (+3.9 ± 2.1). However, when questioned whether there was one particular welcome (5.1 ± 1) or extremely disturbing (6.4 ± 2.4) break during the entire procedure, the latter yielded a higher score (p > 0.05). Acceptance varied according to the surgeon's own esteem of his/her work style. Operators with high self-ratings for "fast" were inclined to put up with shorter breaks ("fast" vs. "slow" = 3.5 ± 1.4 vs. 5.5 ± 0.7, p < 0.05). Overall the scheme was approved (5.9 ± 3.2). CONCLUSIONS: A break scheme has no detrimental effect on patient physiology and is beneficial in infants. It needs careful tailoring to both the surgeon's work situation and self-esteem to gain acceptance. Georg Thieme Verlag KG Stuttgart · New York.
