Efficacy of a portable interface pressure sensor for robotic surgery in preventing compartment syndrome

Background/Objective: This study determines whether the use of a portable interface pressure sensor (Palm Q) for robotic surgery could prevent compartment syndrome. Methods: In the present single center, non-trial observational study, patients diagnosed with gynecological diseases between April 2015 and August 2020 treated with laparoscopic or robotic surgery were enrolled. We assessed 256 cases involving surgery performed in the lithotomy position with an operative time >4 h. The Palm Q device was placed preoperatively on both sides of the patients’ lower legs. The pressure was measured every 30 min preoperatively and intraoperatively and adjusted to ≤30 mmHg. If the pressure reached ≥30 mmHg, the operation was stopped, the patient was repositioned, the leg position was released, the pressure was reduced to ≤30 mmHg, and the procedure was resumed. We compared the maximum creatine kinase levels of the Palm Q and non-Palm Q groups. We also analyzed the correlation between the patients’ symptoms postoperatively (shoulder and leg pain) and compartment syndrome. Results: Our data showed that immediate postoperative creatine kinase levels predict compartment syndrome. Propensity score matching of the 256 enrolled patients resulted in 92 cases (46 per group), balanced for age, body mass index, and lifestyle disease. Creatine kinase levels differed significantly between the Palm Q and non-Palm Q groups (p = 0.041). None of the patients in the Palm Q group experienced well-leg compartment syndrome complications. Conclusion: Palm Q can potentially help to prevent perioperative compartment syndrome.
