Randomized Controlled TrialEffect of dexamethasone on the incidence of post-dural puncture headache after spinal anesthesia: a randomized, double-blind, placebo-controlled trial and a meta-analysis.
The effect of dexamethasone on post-dural puncture headache (PDPH) after spinal anesthesia has not been well elucidated. This randomized, double-blind, placebo-controlled trial was carried out in patients undergoing a cesarean at the Qilu Hospital, Shandong University. The subjects were randomly divided into a placebo and a dexamethasone group. ⋯ The results indicated that prophylactic administration of 8 mg dexamethasone did not have any protective effect against PDPH (31 vs. 18, P = 0.054) and even increased the incidence of PDPH in the first 24 h in parturient patients (25 vs. 11, P = 0.016). Furthermore, the meta-analysis also showed that dexamethasone did not prevent the incidence of PDPH in the postoperative follow-up days (RR 1.05; 95 % CI 0.46-2.38; P = 0.91) and may even have increased the trend in the first 24 h. Prophylactic administration of 8 mg dexamethasone does not have any protective effect against PDPH and may even increase the incidence of PDPH in the first 24 h in patients with spinal anesthesia.

Cardiac surgery with cardiopulmonary bypass has a major impact on the congenital immune response, in which Toll-like receptors (TLRs) are the first line of defence. Decreased surface expression of TLRs and impaired monocyte responsiveness to TLR ligands occur following surgery. However, the clinical implications of this altered immune response are not clear. ⋯ Clinicaltrials.gov identifier: NCT00356746.
