Brief Summary

We aimed to evaluate the analgesic effect of ultrasound guided Superficial cervical plexux block in tympanomastoid ear surgeries by comparing it with conventional general anaesthesia using systemic analgesic through observation of intra- and postoperative requirements of the total dose of systemic analgesics, visual analog scale (VAS) score, total duration of analgesia, vital parameters and the occurrence of any perioperative complications.

Conditions

Pain After Surgery

Keywords

cervical plexus block; hypotensive anesthesia; ear surgery

Outcome Measures

Primary Outcomes (2)

• pain

  monitoring pain score using visual analog score (VAS) postoperative . to evaluate the analgesic effect

  24 hours

• analgesia

  The number of analgesic doses required for each patient as rescue analgesia (when VAS \> 3), will be recorded and statistically compared between the two groups

  24 hours

Study Arms (2)

control group

NO INTERVENTION

will receive only conventional general anasthesia in ear surgery

study group

EXPERIMENTAL

patients will receive superficial cervical plexus block in addittion to general anesthesia

Procedure: nerve block with bupivacaine 0.25%

Interventions

nerve block with bupivacaine 0.25% PROCEDURE

superficial cervical plexus block (superficial CPB ) will be administered in a supine position with the head turned opposite to the side of the block using ultrasound guidance . Local anaesthetic will be injected alongside the posterior border of the muscle 2-3 cm in cranial and caudal directions. Using a 'fan' technique, the local anaesthetic will be administered subcutaneously and behind the sternocleidomastoid muscle. Ten millilitres of 0.25% bupivacaine were injected for each side of the block using a 1.5-inch 24-gauge needle..
