Spots Global Cancer Trial Database for Spinal Versus Epidural Analgesia in Laparotomic Liver Surgery

Study Description

Brief Summary: The purpose of this study is to evaluate the efficacy of spinal analgesia for minor laparotomic hepatectomy compared with epidural analgesia, monitoring visual analog scale (VAS). The investigators expect at least the same post-operative pain control in the two groups (non inferiority of pain control with spinal analgesia compared to epidural analgesia). Second endpoint is to verify whether after spinal analgesia there is a decrease in patient's length of hospitalization according to enhanced recovery after surgery (ERAS) principles.

Detailed Description: Liver surgery is performed under general anesthesia. Loco-regional analgesia is generally performed before general anesthesia induction to obtain the best post-operative pain control,in association with intravenous analgesic drug administration. For minor laparotomic surgery (defined as the resection of up to three hepatic segments), if not contraindicated, in our hospital loco-regional analgesia is performed through the placement of a thoracic (T7-T8 or T8-T9) epidural catheter in which a local anesthetic (usually ropivacaine) and an opioid (usually sufentanil) are administered for the first three post-operative days. This is still considered the gold-standard for pain management in this surgery. In our institute, there is a dedicated acute pain service (APS) for pain management in the post-operative period. APS is also responsible for monitoring, registering and treating all side effects related to both the procedure and the drugs used. In laparoscopic abdominal surgery, instead of epidural analgesia, if not contraindicated, spinal analgesia with low dose morphine before general anesthesia induction is performed. This technique is actually considered efficacy and safe in these type of surgeries. The investigators therefore decided to test the efficacy of spinal analgesia versus epidural analgesia for minor liver surgery since anterior hepatic segments resection is less painful than major liver surgery because it requires less liver manipulation without significant involvement of the Glisson's capsule. This might imply a less incidence of procedure-related side effects such as post-dural puncture headache or site infections. Moreover, spinal analgesia may allow a earlier post-operative patients mobilization and thus a earlier hospital discharge. In this randomized controlled trial, the investigators therefore aim to randomize 40 consecutive patients into 2 arms. The experimental group will receive spinal analgesia (morphine 0.2 mg) for post-operative pain control while the control group will receive epidural analgesia (bolus of ropivacaine 0.2% 4-6 mL followed by continuous epidural infusion of ropivacaine 0.2%: 99 mL + sufentanil 50 mcg/mL: 1 mL). Randomization will be performed with closed opaque envelopes. During surgery, patients will be monitored as usual. Intraoperative blood losses and fluids administration will be recorded. Patients randomized into the epidural group will not receive local anesthetic administration through the epidural catheter during the hepatic resection phase to avoid hemodynamic instability. Once the hepatic resection phase is finished and euvolemic status is recovered, epidural analgesia will be administered as mentioned before. In patients in the spinal group, transversus abdominis plane (TAP) block with ropivacaine 0.375% 20 mL bilaterally or surgical wound infiltration with ropivacaine 0.75% 10- 20 mL will also be performed before anesthesia recovery. In both groups, post-operative pain control will be managed with intravenous acetaminophen 1000 mg 40 minutes before ending of surgery followed by intravenous administration of acetaminophen 1000 mg every 8 hours and a non-steroidal antinflammatory drug (ketorolac 30 mg) as a rescue therapy in the post-operative period if not contraindicated. Patients will be monitored every 24 hours until the achievement of the "ready to discharge" status defined as: * appropriate oral alimentation; * optimal pain control with drugs administered orally; * adequate ability in walking and personal care; * clinical, laboratory and instrumental absence of any post-operative complication; * intestinal function recovery; * patient consent to discharge.
