NCT06108895

Brief Summary

The aim of the present controlled randomized study is to compare between ilioinguinal/iliohypogastric nerve block (IINB) and morphine as adjuncts to spinal anesthesia for cesarean section regarding quality of post-operative analgesia. The researchers will compare between the following groups: Group C, control group; will receive intrathecal 12.5 mg hyperbaric bupivacaine 0.5%, Group I; will receive intrathecal 12.5 mg hyperbaric bupivacaine 0.5% plus bilateral ultrasound guided IINB, and Group M; will receive intrathecal 12.5 mg hyperbaric bupivacaine 0.5% plus 200 mcg morphine to answer the question: Could IINB be an alternative to intrathecal morphine during spinal anesthesia for cesarean section ?.

Outcome Measures

Primary Outcomes (5)

  • pain numeric rating score at rest

    Patients are asked to circle the number between 0 and 10 that fits best to their pain intensity. 0 represents 'no pain at all' where as 10 represents 'the worst pain ever possible'.

    Time 0: at end of surgery (T0); then 4hours (T1), 6hours (T2), 12hours (T3), 18hours (T4), 24hours (T5), 36hours (T6), 48hours (T7), and 72hours (T8) after surgery

  • pain numeric rating score during movement

    Patients are asked to circle the number between 0 and 10 that fits best to their pain intensity. 0 represents 'no pain at all' where as 10 represents 'the worst pain ever possible'.

    Time 0: at end of surgery (T0); then 4hours (T1), 6hours (T2), 12hours (T3), 18hours (T4), 24hours (T5), 36hours (T6), 48hours (T7), and 72hours (T8) after surgery

  • total amounts of rescue morphine

    total amount of intravenous rescue morphine

    at the end of the first 24 hours after surgery

  • time to first ambulation

    number of hours from end of surgery to the time the pateint left the bed

    the time the patient left the bed

  • complications

    pruritus, post-operative nausea and vomiting (PONV) using the PONV intensity score, sedation using Ramsey sedation score, respiratory depression (respiratory rate ≤ 8/min.), and complication related to IINB as improper block, pain, hematoma or infection at the site of injection.

    during the first 72 hours after surgery

Secondary Outcomes (1)

  • Patients' satisfaction

    72 hours after surgery

Study Arms (3)

Group C, control group

NO INTERVENTION

it will receive intrathecal 12.5 mg (2.5ml) hyperbaric bupivacaine 0.5%.

Group I

ACTIVE COMPARATOR

it will receive intrathecal 12.5 mg (2.5ml) hyperbaric bupivacaine 0.5% plus bilateral ultrasound guided IINB after surgery.

Other: ilio-inguinal/ilio-hypogastric nerve block (IINB)

Group M

ACTIVE COMPARATOR

it will receive intrathecal 12.5 mg hyperbaric bupivacaine 0.5% plus 200 mcg morphine in 2.5ml solution.

Other: intrathecal morphine

Interventions

Ultrasound-guided IINBs will be performed by scanning the anterior abdominal wall superior and medial to the anterior superior iliac spine in a line between the anterior superior iliac spine and umbilicus using a linear probe (4-12hertz). Ilioinguinal and iliohypogastric nerves will be identified in the plane between internal oblique muscle and transversus abdominis muscle. After negative aspiration of blood, 20 ml plain bupivacaine 0.25% plus 4mg dexamesathone will be injected. The same technique will be performed in the other side.

Group I

200 mcg morphine intrathecally with bupivacaine

Group M
