Efficacy of Transcutaneous Electrical Nerve Stimulation for Postoperative Pain, Pulmonary Function, and Opioid Consumption Following Cardiothoracic Procedures: A Systematic Review.

OBJECTIVE: Transcutaneous electrical nerve stimulation (TENS) is a minimally invasive method for treating pain. In the most recent review published in 2012, TENS was associated with increased pain relief following cardiothoracic surgery when compared to standard multimodal analgesia. The purpose of this systematic review and meta-analysis is to determine if adding TENS to current pain management practices decreases pain and analgesic use and improves pulmonary function for postcardiothoracic surgery patients. MATERIALS AND METHODS: CINAHL, MEDLINE, Cochrane Database of Systematic Reviews, PubMed, and ClinicalTrials.gov were searched using specific keywords. Covidence was used to screen, select studies, and extract data by two independent reviewers. The Cochrane Risk of Bias tool assessed risk of bias. Visual analog scale (VAS) and pulmonary function data were exported for meta-analysis using a random effects model. RESULTS: The search yielded 38 articles. Eight randomized controlled trials met inclusion criteria for the literature review. Five studies were included in the meta-analysis of pain at 24, 48, and 72 hours postoperatively. Data were analyzed using the standard mean difference (SMD). TENS had a significant impact on VAS at rest (-0.76 SMD [95% confidence interval, CI = -1.06 to -0.49], p < 0.00001) and with coughing (-1.11 SMD [95% CI = -1.64 to -0.56], p < 0.0001). FEV1 improved after 72 hours (1.00 SMD [95% CI = 0.66-1.35], p < 0.00001), as did forced vital capacity (1.16 SMD [95% CI = 0.23-2.10], p = 0.01). CONCLUSION: The addition of TENS therapy to multimodal analgesia significantly decreases pain following cardiothoracic surgery, increases the recovery of pulmonary function, and decreases the use of analgesics.

Pain distraction during awake low anterior resection and Cuddle Delivery initiative for inpatient: frugal procedural options to support surgery in the COVID-19 era.

OBJECTIVE: Since minimally invasive surgery and general anesthesia are both aerosol-generating procedures, their use became controversial during the outbreak of coronavirus disease 2019 (COVID-19). Moreover, social distancing resulted in serious psychological consequences for inpatients. This case report investigates pain distraction during awake laparotomy, as well as new possibilities for emotional postoperative support to inpatients. PATIENTS AND METHODS: A 72-year-old man affected by middle rectal adenocarcinoma underwent lower anterior resection plus total mesorectal excision under combined spinal-epidural anesthesia. A 3D mobile theatre (3DMT) was intraoperatively used for pain distraction. A postoperative "Cuddle delivery" service was instituted: video-messages from relatives and close friends were delivered daily to the patient through the 3DMT. Emotional correlations were investigated through a clinical interview by the psychologist of our Hospital. RESULTS: Intraoperative, as well as postoperative pain, resulted well-controlled: visual analogue scale (VAS) ≤3. Conversion to general anesthesia and postoperative intensive support/monitoring were unnecessary. The "Cuddle delivery" initiative positively fed our patient's mood and attitude, strengthening his bond to life. CONCLUSIONS: During pandemic, awake laparotomy under loco-regional anesthesia may be a crucial option in delivering acute care surgery to selected patients when intensive care beds are unavailable. Our procedure introduces potential ways to optimize this approach.
