Efficacy and Safety of Photobiomodulation for Postoperative Pain After Cesarean Section

Postoperative pain following cesarean section remains a major clinical challenge that can impair early maternal recovery, delay ambulation, and interfere with newborn care. Photobiomodulation (PBM) is a non-invasive light therapy that uses red and near-infrared light to reduce inflammation, stimulate cellular energy (ATP) production, and promote tissue repair. The purpose of this randomized, double-blind, sham-controlled clinical trial is to evaluate the efficacy and safety of portable photobiomodulation using the MitoQUAD® device as an adjunct to standard multimodal analgesia in postpartum women undergoing cesarean section. Participants (N=210) will be randomized (1:1) to receive either active PBM or a sham device in three 15-minute sessions (at 30 minutes, 24 hours, and 36-48 hours post-cesarean). Pain intensity, rescue analgesic use, wound healing, time to ambulation, maternal satisfaction, and adverse events will be monitored over 48 hours.

TAP vs. ESP Blocks for Post-Cesarean Analgesia

This study compares the effectiveness of two ultrasound-guided nerve blocks (TAP block and ESP block) versus standard pain management for relieving pain after a planned cesarean section. Cesarean delivery often causes moderate to severe pain, which can be divided into somatic pain (from the abdominal incision) and visceral pain (from uterine contractions and internal tissues). While transversus abdominis plane (TAP) blocks are commonly used, erector spinae plane (ESP) blocks are a newer technique that may provide better relief for visceral pain. In this randomized controlled trial, 162 women undergoing elective cesarean delivery under spinal anesthesia will be assigned to one of three groups: 1. Bilateral ESP block at the L1 level; 2. Bilateral TAP block; 3. Standard analgesia without nerve blocks. The primary goal is to determine which method provides better control of visceral pain in the first 16 hours after surgery. Secondary goals include assessing somatic pain, time to first mobilization, time to first skin-to-skin contact with the baby, and the need for additional rescue pain medication. The study aims to support early recovery and improve mother-infant bonding by optimizing postoperative pain control.

Interferential Current and Transcutaneous Electrical Nerve Stimulation for Pain After Cesarean Section

This study aims to compare the immediate and short-term effects of interferential current therapy and conventional transcutaneous electrical nerve stimulation (TENS) with placebo stimulation on pain and postpartum comfort following cesarean section. A total of 54 primiparous women aged 18-40 years will be randomly assigned to an interferential current, TENS, or placebo group. Each intervention will be administered for 30 minutes. Pain intensity at rest and during in-bed activities will be assessed before the intervention, immediately after the intervention, and at 1 and 2 hours after the intervention. Postpartum comfort, treatment satisfaction, anxiety, and depression will also be evaluated.

Predictors of Severe Postoperative Pain Within 24 Hours After Elective Cesarean Delivery Under Spinal Anesthesia

This prospective observational study aims to identify predictors of severe postoperative pain during the first 24 hours after elective cesarean delivery under spinal anesthesia. Preoperative, intraoperative, and postoperative factors will be evaluated to determine their association with severe postoperative pain.

Nociception Level Index Monitoring During Cesarean Section

This prospective randomized controlled trial evaluated the effect of nociception level (NOL) index-guided intraoperative analgesia on postoperative pain management in patients undergoing elective cesarean section under general anesthesia. Sixty patients were randomly assigned to either NOL-guided analgesia or standard intraoperative monitoring. The primary outcome was postoperative pain intensity assessed using the visual analog scale (VAS) during the first 24 hours after surgery. Secondary outcomes included postoperative opioid requirements and time to first breastfeeding. The study aimed to determine whether objective intraoperative nociception monitoring could improve postoperative analgesia and enhance early maternal recovery.

Abdominal Ice Application After Cesarean Section

Cesarean section is one of the most commonly performed surgical procedures worldwide, and effective postoperative pain control is important for maternal recovery and patient comfort. This randomized controlled study evaluated whether intermittent abdominal ice application after elective cesarean section could reduce postoperative pain and opioid consumption. Eighty patients undergoing cesarean delivery under spinal anesthesia were randomly assigned to receive either intermittent abdominal ice application in addition to standard multimodal analgesia or standard postoperative care alone. Postoperative pain scores, opioid consumption, patient satisfaction, and postoperative recovery outcomes were evaluated during the first 24 postoperative hours.

Comparison of Combined Spinal Epidural Analgesia and Erector Spinae Plane Block After Elective Cesarean Section

Postoperative pain after cesarean section can significantly affect maternal recovery, early mobilization, and patient satisfaction. Regional anesthesia techniques are widely used to improve postoperative analgesia and reduce opioid consumption. Combined spinal-epidural analgesia is commonly used for cesarean section and provides effective pain control but may be associated with technical difficulties and potential complications. The erector spinae plane block is a newer ultrasound-guided regional anesthesia technique that has shown promising results for postoperative pain management in various surgical procedures. The aim of this study is to compare the postoperative analgesic effectiveness of combined spinal-epidural analgesia and the erector spinae plane block in patients undergoing elective cesarean section. Pain intensity will be assessed using the visual analog scale at multiple postoperative time points. Maternal recovery will be evaluated using the Obstetric Quality of Recovery-11 questionnaire. Secondary outcomes will include postoperative nausea, pruritus, time to first analgesic request, mobilization time, and patient satisfaction. This study will help determine whether the erector spinae plane block can provide comparable or improved postoperative pain control with fewer complications compared to combined spinal-epidural analgesia.
