Pre-incisional Infiltration With Ropivacaine Plus Diprospan for Relieving Postoperative Pain After Laparoscopic Surgery
The Efficacy and Safety of Pre-incisional Infiltration With Ropivacaine Plus Diprospan in Patients Undergoing Laparoscopic Surgery: a Multi-center Randomized Controlled Trial.
Incisional infiltration is the simplest, safest, and most effective anesthesia method for preventing incision pain after laparoscopic surgery, but even using long-acting local anesthetics, the effectiveness of postoperative analgesia can only last for a relatively short period of time. Studies have shown that up to 80% of patients experience postoperative pain following laparoscopic surgery due to inflammation caused by surgical incisions and surrounding tissues, necessitating pharmacological relief. Inflammatory mediators released from the soft tissues around laparoscopic incisions not only significantly alters the chemical microenvironment at the peripheral terminals of nociceptors, directly inducing pain, but also sensitizes afferent fibers, contributing to peripheral sensitization.
Numerous studies have shown that glucocorticoids not only can achieve anti-inflammatory and analgesic effects by inhibiting inflammatory cytokines and inflammatory responses but also can prolong the duration of action of local anesthetics. Preemptive incisional infiltration using local anesthetics with corticosteroids which have potent local anti-inflammatory properties may play a key role in preventing or reducing postoperative pain. The objective of this trial is to determine whether preemptive incisional infiltration with ropivacaine plus diprospan is superior to ropivacaine alone in relieving postoperative pain for adults undergoing laparoscopic surgery. The investigators also compare the effects of the two intervention measures on postoperative pain management, patient safety, and recovery quality.

Grupo de Participantes / Braço |
Intervenção / Tratamento |
|---|---|
|
Comparador Ativo: Pre-incisional infiltration with ropivacaine alone
|
Before the surgery, according to the surgeon's incision marking, the patients accept 30ml of 0.5% ropivacaine infiltrates the incision layer by layer (1ml subcutaneous infiltration at each location, 2ml full layer infiltration, total 3ml).
|
|
Experimental: Pre-incisional infiltration with ropivacaine plus diprospan
|
Before the surgery, according to the surgeon's incision marking, the patients accept 0.5ml of diprospan (1ml diprospan: Betamethasone Dipropionate 5mg and Betamethasone Sodium Phosphate 2mg) plus 15ml of 1% ropivacaine diluted with 0.9% saline to a total volume of 30ml infiltrates the incision layer by layer (1ml subcutaneous infiltration at each location, 2ml full layer infiltration, total 3ml).

Prazo: Dia 7 pós-operatório, mês 1 e mês 3.
|
A Escala de Avaliação Numérica (NRS) designa 0 como representando nenhuma dor e 10 como representando a dor mais severa; pontuações de 1-3 indicam dor leve, 4-6 denotam dor moderada e 7-10 significam dor severa.
|
Dia 7 pós-operatório, mês 1 e mês 3.

|
Adverse events
Prazo: Within 72 hours postoperatively
|
Including local anesthetic poisoning, local hematoma, nausea and vomiting, itching, hypotension, arrhythmia, delirium, etc; Abnormal values in clinical laboratory tests, such as elevated blood glucose levels.
|

Prazo: Data will be collected at 4、12、24、36 and 72 hours postoperatively
|
The Numeric Rating Scale (NRS) designates 0 as representing no pain and 10 as representing the most severe pain, scores of 1-3 indicate mild pain, 4-6 denote moderate pain, and 7-10 signify severe pain.
|

|
The wound healing score is evaluated by independent researchers based on the wound healing score table, which includes three aspects: skin healing, incision infection, and hair growth.
The total score is obtained by adding up the three scores.
Excellent wound healing: 3 points; Good wound healing is 4-5; Poor wound healing: total score greater than or equal to 6 points.

Postoperative 72 hours、1 and 3 months
|
|
Postoperatively and patient and observer scar assessment scale
Prazo: Postoperative 72 hours、1 and 3 months
|
Postoperatively and patient and observer scar assessment scale: the observer scores the scar based on the distribution of blood vessels around the incision, color, scar thickness, surface roughness, area, and softness.
Each score ranges from 1 to 10 points and higher scores indicating more severe scars; The patient evaluates the scar based on whether there is pain or itching, color, softness, thickness, and self-perception.
Each score range is also 1-10 points, with 1 point indicating no difference from normal skin and a higher score indicating more severe scars.
