Summary

Pain is common in the first 2 days after major craniotomy. Inadequate analgesia may lead to an increased risk of postoperative complications. Most pain following craniotomy arises from the pericranial muscles and soft tissues of the scalp. Scalp nerve blocks with local anesthesia seem to provide effective, safe, however transient postoperative analgesia which does not seem to meet the requirements of craniotomy. Currently, peripheral dexamethasone has been observed to significantly prolong the duration of analgesia of nerve blocks (e.g., saphenous nerve block, adductor canal block, thoracic paravertebral block, brachial plexus nerve block). On the contrary, a study reported that perineural dexamethasone did not appear to prolong the analgesic time after supratentorial craniotomy. However, all patients in this study were given 24 mg of oral or intravenous dexamethasone regularly at least 7 days during the perioperative period, which possibly masked the role of single local low doses of perineural dexamethasone. Therefore, the analgesic effect of single dexamethasone for scalp nerve blocks without the backdrop of perioperative glucocorticoid deserves further clarification.

Conditions

  • Postoperative Pain
  • Craniotomy
  • Dexamethasone
  • Scalp Nerve Blocks

Interventions

DRUG

Bupivacaine

The control group will receive scalp nerve blocks with 0.5% bupivacaine with epinephrine at 1:200,000, plus normal saline 1 ml. The anesthesiologist will perform scalp nerve blocks based on the group allocation 10 mins before the incision. Scalp nerve blocks will be performed according to the technique previously described by Pinosky et al.

DRUG

Dexamethasone combined with bupivacaine

The DEX4mg group will receive scalp nerve blocks with 0.5% bupivacaine with epinephrine at 1:200,000, plus 4 mg dexamethasone (1 ml). The anesthesiologist will perform scalp nerve blocks based on the group allocation 10 mins before the incision. Scalp nerve blocks will be performed according to the technique previously described by Pinosky et al.
