Abstract
Background
Shivering is known to be a frequent complication in patients undergoing surgery under neuraxial anesthesia with incidence of 40–70%. Although many pharmacological agents have been used to treat or prevent postspinal anesthesia shivering (PSAS), the ideal treatment wasn’t found. This study evaluated the efficacy of paracetamol and dexamethasone to prevent PSAS in patients undergoing lower abdominal and lower limb surgeries.
Methods
Three hundred patients scheduled for surgeries under spinal anesthesia (SA) were allocated into three equal groups to receive a single preoperative dose of oral paracetamol 1 g (P group), dexamethasone 8 mg intravenous infusion (IVI) in 100 ml normal saline (D group) or placebo (C group), 2 h preoperatively, in a randomized, double-blind trial. The primary endpoint was the incidence of clinically significant PSAS. Secondary endpoints included shivering score, the change in hemodynamics, adverse events (e.g., nausea, vomiting and pruritis) and patients` satisfaction.
Results
Clinically significant PSAS was recorded as (15%) in P group, (40%) in D group and (77%) in C group (P < 0.001). The mean blood pressure values obtained over a 5-25 min observation period were significantly higher in the D group (P < 0.001). Core temperature 90 min after SA was significantly lower in the 3 groups compared to prespinal values (P < 0.001). Nausea, vomiting and pruritis were significantly higher in the C group (P < 0.001). P and D groups were superior to C group regarding the patients’ satisfaction score (P < 0.001).
Conclusion
Paracetamol and dexamethasone were effective in prevention of PSAS in patients undergoing lower abdominal and lower limb surgeries compared to placebo controls.
