Summary

The majority of cases undergoing hepatectomy suffer from inadequate postoperative analgesia. Therefore, multimodal analgesic techniques are required to relieve pain and discomfort such as intravenous, and epidural analgesia, and peripheral nerve blocks. Although epidural catheters are efficient to provide perioperative analgesia, in this type of surgery patients may be more susceptible to catheter related complications due to the alteration in coagulation parameters. That is why safer alternatives are sought for those patients. The use of patient-controlled analgesia (PCA) for postoperative pain management improves patients' quality of recovery. However, there are many concerns regarding the type of opioids used in PCA such as overdosing, underdosing, and the effect of the hepatectomy on the drug metabolism in those patients. External oblique intercostal plane block (EOI block) is a relatively novel block used in upper abdominal incisions especially subcostal laparotomy to provide intraoperative and postoperative analgesia.

This study aims to compare the efficacy of Bilateral External Oblique Intercostal Plain Block versus PCA in pain management and reduction of opioid use in hepatectomy surgery done by subcostal incision.

Conditions

  • Provide Post Hepatectomy Pain Control

Interventions

PROCEDURE

External Oblique Intercostal Plane Block

The block is performed before skin incision by a specialized anesthetist. With the patient positioned in the supine position with their ipsilateral arm abducted, the skin was sterilized, using the high frequency linear probe (M-Turbo HF 38 transducer 13- 6 MHz) of Fujifilm Sonosite ultrasound is placed over the sixth rib medial to the anterior axillary line approximately in midclavicular line in a parasagittal orientation. A 20-guage needle is inserted in a cephalocaudal direction, and the external oblique intercostal plane was hydro dissected with saline. After hydro dissection, the needle is advanced 1 to 2 cm, and 20 mL of 0.25% bupivacaine (Sunny Pharmaceutical) with 4 mg dexamethasone as an additive was administered. The same procedure will be done at the other side (bilateral external oblique intercostal plane block).

DEVICE

Patient controlled analgesia

Patients in group will receive intravenous patient controlled analgesia device 100 ml (Accuafuser 100 mL, basal rate 4 mL/hr., bolus 0.5 mL/time, and lock time 15 minutes) for postoperative pain management that will contain 30 mg morphine (loading dose0.1mg/kg) will be given by infusion over 10 minutes then accuafuser will be connected),8 mg dexamethasone and 8 mg ondansetron diluted in 100 ml saline.
