BACKGROUND: The incidence of postoperative nausea and vomiting (PONV) after microvascular decompression (MVD) surgery is high; however, its underlying mechanisms remain unknown. Serum 5-hydroxytryptamine (5-HT) levels are elevated in patients with PONV. However, the relationship between 5-HT and patients experiencing PONV after MVD surgery is still unknown. Therefore, we hypothesized that 5-HT levels are associated with PONV after MVD surgery.
METHODS: This prospective study included 85 patients with hemifacial spasm who received MVD surgery. Blood samples were collected preoperatively, postoperatively, and on postoperative day 1, and cerebrospinal fluid samples were collected intraoperatively. 5-HT levels were detected by enzyme-linked immunosorbent assay (ELISA). The incidence and severity of PONV were evaluated at 2, 6, and 24 h after MVD surgery.
RESULTS: In the multivariate regression analysis, PONV within 24 h after MVD surgery was associated with elevated cerebrospinal fluid 5-HT levels [odds ratio (OR) = 1.21, 95% confidence interval (CI): 1.01-1.45, p = 0.044], and reduction of intraocular pressure [OR = 11.54, 95% CI: 1.43-92.84, p = 0.022]. Receiver operating characteristic curve analysis revealed an area under the curve of 0.873 (95% CI: 0.77-0.98, p < 0.001).
CONCLUSION: Our study found that the cerebrospinal fluid 5-HT levels is an independent risk factor for PONV within 24 h after MVD surgery.
