Pruritus Vulvae
Conditions
Brief summary
OBJECTIVE: To investigate the inhibitory effect of different doses of propofol on perineal pruritus induced by dexamethasone sodium phosphate injection in women, with a view to providing clinical reference for comfortable clinical care in day surgery. METHODS: One hundred and fifty patients with ASA classification I or II undergoing elective day surgery were randomly divided into six groups of P1, P2, P3, P4, P5 and D1, with 25 cases in each group. Before administration of dexamethasone, propofol injection 0.1 mg/kg, 0.2 mg/kg, 0.3 mg/kg, 0.4 mg/kg and 0.5 mg/kg were given intravenously in groups P1, P2, P3, P4 and P5, respectively (injection rate was 5 s), followed by 30 s of intravenous dexamethasone sodium phosphate 10 mg in all five groups; 5 ml of saline was given in group D1, and 30 s After that, dexamethasone sodium phosphate injection was given (injection speed was 5s in all five groups). The perineal itching, the onset and duration of itching, the visual analogue score (VAS) of itching, the sleep disorder sedation score (Ramsay score) and the occurrence of adverse reactions were recorded in the five groups.
