5. Study Description
Brief Summary
The purpose of this study is to assess the effect of low-pressure pneumoperitoneum on post operative pain and inflammation in patients undergoing elective laparoscopic cholecystectomy by comparing it to standard practice.
Detailed Description
After obtaining informed consent from eligible study participants. patients were randomized into one of two masked groups, labelled red and green. The red-label group was operated at standard-pressure pneumoperitoneum, while the green-label group was operated at low-pressure pneumoperitoneum. Baseline blood samples were obtained pre-operatively for ten inflammatory markers, patients' demographics and intra-operative details collected, then post-operative pain and change in inflammatory markers were followed.

Parallel Assignment
Model Description
participants were divided into two masked groups, labelled red and green; those operated at low-pressure pneumoperitoneum (green-label) and those operated at standard-pressure pneumoperitoneum (red-label).
Masking
ParticipantCare ProviderInvestigatorOutcomes Assessor
Masking Description
none of the participants knew at which pressure they will be operated on, nor the physicians who followed participants at floor or those analyzing blood samples, not the assigned physician to collect data, nor the personnel doing the analysis.
only the operating surgeon and circulating nurse were aware of the meaning of the participant assigned label at time of operation. The masking was revealed post completion of analysis.
