Comparative Study Between Ultrasound Guided External Oblique Intercostal Plane Block and Erector Spinae Block for Postoperative Analgesia in Hepatectomy Incision in Cancer Patients
Management of acute post-operative pain has received keen attention in recent years with considerable concurrent advancement in the field.
The importance of effective pain relief has long been realised, and acute pain services (APS) are operational in majority of the hospitals in the developed world for decades.
Postoperative pain following abdominal surgery if severe enough may cause several side effects as "splinting, hypoventilation, atelectasis, immobility, hypercoagulability, thromboembolic events, vasoconstriction, tachycardia, increased systemic vascular resistance, dysrhythmias and cardiac ischemia in susceptible patients, insomnia, anxiety, feeling of helplessness".
Ultrasound-guided fascial plane blocks have been rapidly incorporated into regional anaesthesia practice in recent years as an alternative to neuraxial techniques and involve injection into a tissue plane to provide analgesia in various anatomic areas.
External oblique intercostal plane block (EOIPB) is a novel block, which has been described as an important modification of the fascial plane blocks that can consistently involve the upper lateral abdominal walls.
The erector spinae plane (ESP) block is a new regional aesthetic technique that can be used to provide analgesia for a variety of surgical procedures or to manage acute or chronic pain. The technique is relatively easy to perform on patients.
The ESPB involves injection of local anaesthetic in the erector spinae fascial plane, superficial to the tip of the transverse process of the vertebra and deep to the erector spinae muscle.
Inclusion: Cancer patients undergoing hepatectomy under general anaesthesia; Aged 18 years or older; ASA II \& III; BMI >20kg/m2 and <35kg/m2.
Exclusion: History of psychiatric disorders or history of major depression; Major medical conditions (heart failure , chronic kidney disease ,patient on dialysis).
