A Clinical Study on Vagus Nerve Blockade at the Gastroesophageal Junction Combined With Tegileridine in the Very Early Postoperative Recovery Following Bariatric Surgery
This study aims to investigate, through a prospective randomized controlled clinical trial, the clinical value of vagal nerve block at the gastroesophageal junction combined with tizanidine in the very early postoperative recovery following bariatric surgery. Patients who have undergone bariatric surgery often experience visceral pain due to the inflammatory response triggered by partial gastrectomy. Conventional analgesic regimens have limited efficacy in controlling this type of visceral pain, whereas vagus nerve block at the gastroesophageal junction can directly block the transmission of pain signals from this region, thereby specifically alleviating visceral pain; the combined use of tegileridine could reduce postoperative opioid dosage and lower the risk of related adverse reactions. By comparing these two different analgesic regimens, this study examines their effects on patients' postoperative pain intensity, early mobilization, and adverse reactions such as respiratory depression, nausea, vomiting, and constipation. This study aims to clarify the efficacy and safety of this combined regimen in precisely relieving visceral pain, optimizing perioperative analgesia, reducing opioid-related complications, alleviating gastrointestinal adverse reactions, promoting early ambulation, and accelerating recovery, thereby providing clinical evidence for the establishment of a more comprehensive and individualized multimodal analgesia and Enhanced Recovery After Surgery (ERAS) system for bariatric surgery.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Visual analogue scale (VAS) Score
Lasso di tempo: postoperative 0, 2, 6, 12, and 24 hours
|
The VAS score refers to drawing a 10-cm scale on a piece of paper. One end of the scale is marked as 0, indicating no pain; the other end is marked as 10, indicating severe pain; the values in between represent different degrees of pain. |
postoperative 0, 2, 6, 12, and 24 hours

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Quality-of-Recovery 15 (QoR-15) Score
Lasso di tempo: postoperative 1 day
|
The QoR-15 includes 5 items related to physical comfort, 4 items regarding emotional state, 2 items concerning self-care ability, 2 items related to psychological support, and 2 items about pain. There are a total of 15 subjective parameters. Each item is scored on a scale of 0 to 10. The total score of QoR-15 ranges from 0 to 150. The higher the score, the better the condition. |

Incidence of postoperative respiratory depression
Lasso di tempo: postoperative 1, 2, 3 days
|
Postoperative respiratory depression is defined as a sustained (>1 minute) decrease in oxygen saturation to <90%, or a respiratory rate of <8 breaths per minute, or a decrease in oxygen saturation to <94% accompanied by a respiratory rate of <10 breaths per minute, requiring supplemental oxygen to maintain oxygen saturation (SpO₂) >94%, and in the absence of obvious upper airway obstruction. |
