The Effect of Pneumoperitoneum on the Ankle-brachial Index of the Patients Undergoing Laparoscopic Cholecystectomy: An Observational Study.

BACKGROUND

Improvement in the perioperative care has led to increased use of minimally invasive surgeries. Multiple physiological changes during minimally invasive surgeries are attributed to the creation of pneumoperitoneum.

MATERIALS AND

METHODS

One hundred and nine patients who underwent laparoscopic cholecystectomy at a tertiary care hospital in north India meeting the inclusion and exclusion criteria were enrolled.

RESULTS

Out of the total 109 patients, 13 were males and 96 females (M:F = 1:7.3), the mean basal metabolic rate was 28.95 kg/m2. The mean systolic and diastolic blood pressure of the upper limb were 134.33 + 17.545 and 80.69 + 11.59 respectively. The mean systolic and diastolic blood pressure in lower limb (LL) were 142.32 + 21.552 and 79.44 + 11.94, respectively. Significant rise in the SBP was noticed in LL at the time of creation of Pneumoperitoneum and after changing the position for surgery (P < 0.05). The diastolic pressure in the LL rises significantly in the LL after creation of pneumoperitoneum, at induction, after reverse Trendelenburg position and extubation (P < 0.05). The mean arterial pressure increased significantly in the LL after the creation of pneumoperitoneum and persisted till the extubation (P < 0.05). A significant rise of ankle-brachial index (ABI) was observed in the patients after the creation of pneumoperitoneum and it remained significant till 15 min into surgery (P < 0.05). There was no correlation of ABI with weight and age of the patients on Pearson correlation.

CONCLUSION

There is rise in ABI of the patients undergoing laparoscopic cholecystectomy at the time of creation of pneumoperitoneum, after Trendelenburg position and 15 min into surgery.
