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.

Interventions

insufflation of the abdomen for creation of pneumoperitoneum, pressure set points between 8 to 10 mm Hg

insufflation of the abdomen for creation of pneumoperitoneum, pressure set points between 12 to 14 mm Hg

QUADRUPLE (Subject, Caregiver, Investigator, Outcomes 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.

Intervention 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).

Design outcomes

Primary

MeasureTime frameDescription
assessment of pain with SPS-11 at 6hr post-oppre-op to 6 hours post opmeasure difference in pain on the 11-point short pain scale (SPS-11) at 6-hour post-op compared to baseline at pre-op, minimum score of 0 , maximun score of 10 = pain at 6 hour post op - pain at pre-op
change in IL-6pre op to 24 hours post -opmeasure differance of inflammatory marker from baseline = baseline value- post op value (calculated in pg/mL) post-op collected at 24 hours from end of surgery

Secondary

MeasureTime frameDescription
assessment of difficulty of surgerystart to end of the study, 1 yearto measure difference in surgery difficulty between the two groups using a scale of 1; easy, 2; moderate, 3; difficult. analysis done using Chi-square cross table on SPSS V 1.0.0.1406
assessment of difference in operation timestart to end of the study, 1 yearto look for difference in operation time between the two groups, calculated in minutes. analysis done using Student's 2-tailed t-test on SPSS V 1.0.0.1406
