Overview
Brief Summary
A comparative study between ultrasound guided thoracic paravertebral block VS ultrasound guided serrartus anterior muscle block in video-assisted thoracoscopic surgeries as regard their effectiveness in post-operative analgesia
Detailed Description
The use of loco-regional analgesia is recommended to control postoperative pain after VATS as it allows opioid sparing and facilitates early postoperative rehabilitation. Different loco-regional analgesic techniques could be used to control pain after thoracic surgery such as a paravertebral block, an intercostal block and serratus plane block. In this study, Thoracic paravertebral nerve block will be compared to Serratus anterior nerve block, both will be done Ultrasound guided (USG) using bupivacaine (0.25%) for postoperative analgesia.

Eligibility Criteria
Inclusion Criteria
- •Patients American Society of Anesthesiologists physical status (ASA) I to II
- •Both sexes.
- •Aged ≥ 20 to ≤ 65years.
- •Scheduled for VATS under general anesthesia.
Exclusion Criteria
- •Patient's refusal.
- •Patients American Society of Anesthesiologists physical status (ASA) III to IV
- •Patients with major spine deformities.
- •Disruption of the local anatomy, secondary, for instance, to the presence of chest drains or surgical emphysema, resulting in difficulty in ultrasound interpretation and distortion of tissue planes.
- •Patients with bleeding disorders and coagulopathy.
- •Infection at the injection site.
- •Known allergy to local anesthetics.

Outcomes
Primary Outcomes
visual analog scale (VAS)
Time Frame: the first 24 hours postoperatively
Postoperative pain will be assessed at time of evaluation or at any time the patient is complaining of pain by using visual analog scale (VAS) and VAS more than 4 will be managed by injection of nalbuphine 5mg intravenously as a first rescue analgesia to reduce VAS score ≤ 3
total amount of opioid consumption in the two groups according to change in VAS score
Time Frame: the first 24 hours postoperatively
Postoperative pain will be assessed at time of evaluation or at any time the patient is complaining of pain by using visual analog scale (VAS) and VAS more than 3 will be managed by injection of nalbuphine 0.05mg / kg intravenously as a first rescue analgesia to reduce VAS score ≤ 3 and another titrating dose (2-3 mg nalbuphine) will be considered if the patient is still complaining in order to reach VAS score ≤ 3 (with maximum dose of 10 mg nalbuphine at a time)
Secondary Outcomes
- onset of ambulation(first 24 hours postoperatively)
- The onset of 1st analgesic request(The first 24 hours postoperatively)
- mean arterial blood pressure of the patients(first 24 hours postoperatively)
- complication of nerve block(first 24 hours postoperatively)
- heart rate of the patients(first 24 hours postoperatively)
