Clinical Trial Summary

The purpose of the intraoperative use of opioids is to reduce the amount of sedative medication and to ensure effective analgesia. But pain is an unpleasant sensory and emotional experience (a cognitive perception) that cannot occur with sufficient depth of anesthesia (even without opioids). So a more reasonable explanation for analgesia should be anti-nociception and the resulting inhibition of the response to surgical stress. Since multiple mediators are involved in nociceptive pathways, antinociception can also be acquired through multiple mechanisms. However, there is no single ideal harm drug to replace opioids, which often requires two or more drugs to meet clinical needs. While regional block attenuates the stress response to surgery and sympathetic activation because of afferents to block nociceptive stimuli, and has an important role in the implementation of OFA. Combined with the clinical characteristics of the LSG, investigators developed the transverse abdominis fascia block (transversus abdominis plane TAP) in combination with esketamine (esketamine), dexmedetomidine (dexmedetomidine, DEX) of opioid-free anesthesia (opioid free anesthesia, OFA) and the analgesic regimen (TEDOFA), Reduce patient pain scores, nausea and vomiting after LSG based on perfect analgesia and adequate anti-sympathetic response, As well as the other complications, Promote the accelerated postoperative recovery of patients undergoing LSG, And reduce the incidence and severity of postoperative chronic pain.

Intervention

Drug:
• Opioid-free Analgesics (esketamine, dexmedetomidine)
opioid free group: After infusion of a loading dose of dexmedetomidine, intravenous midazolam 2mg, propofol 2mg kg-1, esketamine 0.5 mg kg-1, rocuronium 0.6-1mg kg-1, and 3min after endotracheal intubation. Intravenous continuous infusion of propofol, esketamine and dexmedetomidine hydrochloride mixture (esketamine 50mg + dexmedetomidine hydrochloride 150 ug + 0.9% saline 50ml in the same 50ml syringe) 0.1ml kg-1 h-1-0.2 ml kg-1 h-1 (equivalent to esketamine 0.1-0.2mg kg-1 h-1; Dexmedetomidine hydrochloride 0.3-0.6 µ g kg-1 h-1) maintains a BIS value between 40-60, 10-20mg / time was added as appropriate.
• Opioid Anesthetics (sufentanil and remifentanil)
Intravenous midazolam 2mg, propofol 2mg kg-1, sufentanyl 0.3-0.5 µ g kg-1, rocuronium 0.6-1mg kg-1,3min before endotracheal intubation. After successful endotracheal intubation, continuous intravenous infusion of propofol and remifentanil was started to maintain BIS values between 40-60, and rocuronium 10-20mg / time as appropriate. After the start of surgery, 10-20 µ g of sufentanil was added according to blood pressure and heart rate. At the end of the operation, 5mg and 50mg were injected before the end of the operation, and propofol and remifentanil were stopped at the end of the operation

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	15-item recovery quality scale score 48 hours after surgery	The QoR-15 scale is a global measure of postoperative recovery, with scores ranging from 0 (extremely poor QoR) to 150 (excellent QoR). QoR-15 has become the most widely reported indicator for the evaluation of postoperative life treatment in patients. Using wherever possible QoR-15 item scores on postoperative day 3, QoR-15 with very good validity, and good reliability, responsiveness and clinical acceptability, these data suggest that QoR-15 is an excellent patient-centered measure of postoperative QoR. Patient Acceptable symptom status describes the lowest absolute score considered by the patient to represent a healthy or good status health scale. A QoR-15 score of 118 or more indicates a good postoperative recovery	48 hours after surgery
Primary	15-item recovery quality scale score 24 hours before surgery	The QoR-15 scale is a global measure of postoperative recovery, with scores ranging from 0 (extremely poor QoR) to 150 (excellent QoR). QoR-15 has become the most widely reported indicator for the evaluation of postoperative life treatment in patients. Using wherever possible QoR-15 item scores on postoperative day 3, QoR-15 with very good validity, and good reliability, responsiveness and clinical acceptability, these data suggest that QoR-15 is an excellent patient-centered measure of postoperative QoR.
