During continuous peripheral nerve blocks, infusion adjustments are essential for postoperative analgesia without side effects. Beside, physicians and nurse visits related to pump's settings and monitoring are time consuming and costly. We hypothesized that a remote control of pump's settings, by telemedicine transmission, adjusted to patients' feedbacks, is feasible and interesting in optimizing patient's postoperative pain management.


Fifty-nine ASA physical status I and II patients were included. Ropivacaine 0.2% was infused during 72 h in CPNB catheters. After returning to the surgical ward, the patient was allowed to answer a 10 indicators questionnaire 3 times a day (8.00 AM, 2.00 PM, 8.00 PM), or unlimited on patient's demand. This information was transmitted from the pump to a server through the Internet. If one indicator was out of the predefined thresholds, the anesthesiologist in charge was immediately informed by texto on his cell phone. The anesthesiologist connected to the website, checked the data from the patient and modified the settings of the pump by remote control according to a written protocol. The changes need a secure access with a password and a confirmation. The number of settings changes, the time to realize the procedure and the adverse events related to the technique were noted. When the catheter was removed, the pump was unassigned to the patient and the data archived.


Thirty sciatic, 24 femoral and 5 interscalene catheters were inserted in 59 patients. Five catheters were accidentally removed before the end of the 72-h period. The median VAS pain values at rest and during movement were respectively at 2 and 3. Sixteen patients complained about numbness promoting 2 (0-3) changes in pump settings; 9 about motor blockade with 1 (0-2) change; 5 about difficulties for physiotherapy with 1 (0-3) change. The mean time of pump settings modification after response to questionnaire or voluntarily patient's alert was 15 ± 2.2 minutes. Early physiotherapy in the surgical ward was totally uneventful in 54 patients. The mean value of satisfaction scale of the patients was 8.4 ± 1.6. No adverse event necessitated a postoperative analgesia technique change.


Remote control pump's feedbacks and e-settings for postoperative analgesia using CPNB permitted a real adaptation to patients' needs, complaints and pain VAS values without nurse and physician physical intervention.
