- Brief Summary
The anesthetic techniques for videolaparoscopic surgery include general anesthesia, and locoregional anesthesia in association with general anesthesia in order to reduce or abolish post-operative pain with a simultaneous reduction in the use of opioids and days of hospital stay.
From the studies published so far on videolaparoscopic surgery in general, it is clear that the transversus abdominal plane (TAP) block could have a role in reducing the stretch wall pain secondary to pneumoperitoneum and incisional, although its role in this regard is not yet clear, nor significant statistically results have been produced. The use of erector spinae plane (ESP) block for the management of visceral pain is finding more and more space in the literature, with promising results.
For videolaparoscopic gynecological surgery, the techniques of locoregional anesthesia studied in association with general anesthesia, up to now, include wall blocks, TAP block and ESP block, while neuraxial anesthesia has no indications in this regard.
Although videolaparoscopic hysterectomy is considered less painful than the open-abdomen technique, it requires careful management of post-operative pain. The pain of this surgery is the result of the sum of incisional pain, at the insertion points of the laparoscopic trocars, pain due to pneumoperitoneum usually referred to the shoulder, and visceral pain purely dependent on surgical maneuvers. There is currently no strong evidence to support the use of locoregional anesthesia techniques in videolaparoscopic gynecological surgery. Few studies have been produced about this topic, and they are mostly case series or randomized controlled trials that take into consideration only one technique among those possible. To date, no study compares the various techniques to evaluate the possible superiority of one over the other.
In our hospital anesthesists carry out, in normal clinical practice, all the aforementioned local anesthesia techniques.
The purpose of our work is to evaluate, with a randomized non-sponsored study, the efficacy of the ESP block and the TAP block for intra and post-operative pain control in videolaparoscopic hysterectomy, and to compare the two techniques.
Based on the evidence available in the literature, the two techniques are already part of the current clinical practice of the Anesthesia Unit of our hospital and the choice of one technique over the other is based on anesthetist clinical evaluation to date. The anesthetists involved in the study are adequately trained on both anesthetic procedures.

Group Intervention Description General anesthesia + ESP block General anesthesia + ESP block Erector spinae plane (ESP) block: 20 minutes before surgery. T8 level bilaterally, ropivacaine 0.37% 20ml + dexamethasone 2mg per side. Induction: Remifentanil in TIVA, Propofol 2 mg/kg/h and Rocuronium 0.6 mg/kg. Maintenance: TIVA with Propofol, the infusion rate will be adjusted according to the BIS values (30 \<BIS \<50). Patients will receive additional remifentanil by infusion at 0.02 mcg/kg/min per time if blood pressure and heart rate values exceed 20% pre-operative baseline values. Additional rocuronium 0.1 mg/kg based on clinical needs and TOF monitoring. Analgesic starter bolus: 30 minutes before the end of the surgery, paracetamol 1 gr ev and ketorolac 30 mg ev. Postoperative pain: paracetamol 1 gr ev every 8 hours for 36 hours; ketorolac 30 mg ev if NRS \>4 / morphine 2 mg ev if NRS \>4 30 min after ketorolac administration. In case of nausea and vomiting ondansetron 4 mg ev. General anesthesia + TAP block General anesthesia + TAP block Induction: remifentanil in total intravenous anesthesia (TIVA), Propofol 2 mg/kg/h and Rocuronium 0.6 mg/kg. Transversus abdominis plane (TAP) block: 20 minutes before surgery. Ropivacaine 0.37% 20ml + dexamethasone 2mg per side. Maintenance: TIVA with Propofol, the infusion rate will be adjusted according to the bispectral index system (BIS) values (30 \<BIS \<50). Patients will receive additional remifentanil by infusion at 0.02 mcg/kg/min per time if blood pressure and heart rate values exceed 20% pre-operative baseline values. Additional rocuronium 0.1 mg/kg based on clinical needs and train of four (TOF) monitoring. Analgesic starter bolus: 30 minutes before the end of the surgery, paracetamol 1 gr ev and ketorolac 30 mg ev. Postoperative pain: paracetamol 1 gr ev every 8 hours for 36 hours; ketorolac 30 mg ev if NRS \>4 / morphine 2 mg ev if NRS \>4 30 min after ketorolac administration. In case of nausea and vomiting ondansetron 4 mg ev.
- Primary Outcome Measures
Name Time Method Postoperative pain control 12 hours Evaluate the difference between the two groups regarding post-operative pain using Numeric Rating Scale (NRS) 0= better outcome; 10=worse outcome Score will be measured on the numeric rating scale (NRS), an NRS ≤ 4 will be considered as effective antalgic coverage.
- Secondary Outcome Measures
Name Time Method Intra operative use of opioids. Surgery time. Mcg of Remifentanil consumed during surgery.
Post operative use of non-steroidal anti-inflammatory drugs 2-6-12-24-36 postoperative hours Mg of ketorolac or any others anti-inflammatory drugs administered after surgery.
Days of hospital stay 3 days The number of days of hospitalization after surgery will be assessed
Assessment of patient satisfaction with the anesthesiological technique 36 hours Patients is requested to fill out a pre-printed sheet on their judgment of the anesthesiological procedure, in which they can express a value from 0 to 5, where 0 indicates "entirely dissatisfied" and 5 indi- cates "very satisfied"expressed by the patient according to the following scale: satisfied, very satisfied, not at all satisfied
Post operative use of opioids 2-6-12-24-36 postoperative hours Mg of opioids administered after surgery.
Postoperative nausea and / or vomiting 2-6-12-24-36 postoperative hours Quantity of antiemetic drugs required to control nausea and vomiting episodes
