Spinal Anesthesia With Bupivacaine Versus Prilocaine on Postoperative Shivering After Inguinal Hernia Repair

Trial design

Treatments tested in this trial

• Bupivacaine Spinal Anesthesia

  Drug DrugA medicine being studied. This category can also include a placebo used for comparison.

  Group B: (n=40) patients receiving hyperbaric bupivacaine 0.5% (Marcaine, Sunny Medical, Egypt).

• Prilocaine spinal anesthesia

  Drug DrugA medicine being studied. This category can also include a placebo used for comparison.

  Group P; (n=40) will receive prilocaine2% (Takipril, Sunny Medical, Egypt).

• Spinal Anesthesia (bupivacaine) spinal anesthsia (prilocaine)

  Drug DrugA medicine being studied. This category can also include a placebo used for comparison.

  In both groups the patients will be in the sitting position after preparation and draping of the patient's back. A skin wheal will be made by 1 ml of lidocaine HCl 2% at L3-4 interspace using a 25-gauge needle. Hyperbaric bupivacaine 0.5% will be given in dose (15mg) in group B and hyperbaric prilocaine2% in dose (60mg) in Group P. Anesthesia will be prepared by personnel not involved in this study. Patients will be supplemented with oxygen 5.0 l/minute by face mask. Time to achieve T10 dermatome will be recorded also motor level by modified Bromage motor blockade score; 4=no motor block, 3=can flex leg at knee, 2=can flex leg at the ankle and 1= complete motor block. The time needed to reach the maximum block will be recorded. In both groups the hemodynamic parameters will be recorded before block, immediately after block then every 5 min till end of the operation. Need for sedation or analgesia will be recorded.
