The aim was to evaluate the clinical findings of patients who admitted to the hospital with the diagnosis of grayanotoxin/mad honey poisoning. Thirty-three patients were included in this study. Three patients were female (9%) and the others male (91%). Median age of patients was 52 (42-68). The most frequently observed findings were sinus bradycardia (91%), nausea-vomiting (81.8%), and dizziness (78.8%). Average heart rate was 55.35 +/- 6.72 beats/min. Mean systolic and diastolic blood pressures were 77.86 +/- 16.64 mmHg and 46.42 +/- 12.30 mmHg, respectively. Mad honey poisoning is an important problem that is life-threatening in the Black Sea region of Turkey.
Background: This study investigated the effect of injection of rocuronium or sugammadex alone and rocuronium + sugammadex on urea, creatinine, electrolyte levels, and histopathological findings in rats. Methods: Thirty-six SpragueDawley male rats were divided to receive intravenously 16 or 96 mg/kg sugammadex, 1 mg/kg rocuronium, 1 mg/kg rocuronium + 16 mg/kg sugammadex, or 1 mg/kg rocuronium + 96 mg/kg sugammadex. The control group received an equal volume of physiological serum. Rats receiving rocuronium were ventilated until resumption of spontaneous ventilation and followed for 72 h. Blood samples were withdrawn from the tail vein to measure urea, creatinine, and electrolyte values; then both kidneys were excised, and the tissues were used for histopathological examination. Results: Rats receiving rocuronium and high doses of sugammadex (96 mg/kg) showed increased glomerular vacuolation, tubular dilatation, vascular vacuolation and hypertrophy, lymphocyte infiltration, and tubular cell sloughing compared to the control group (p = 0.002). Biochemical markers of renal function were not significantly altered after treatment with high doses of sugammadex. Conclusion: The elimination half-life of the rocuronium-sugammadex complex was found to be greater than that of free rocuronium or sugammadex, which led to marginal histopathological changes in the kidney without affecting any renal functions.
SummaryWe investigated the effect of rocuronium-and sugammadex-induced mast cell increase and degranulation in rat portal triads. Forty-two rats, in six groups, received either rocuronium 1 mg.kg ; rocuronium 1 mg.kg )1 and 5 min later, sugammadex 15 mg.kg; rocuronium 1 mg.kg )1 and 5 min later, sugammadex 100 mg.kg; or isotonic saline. Total mast cell numbers were significantly higher with rocuronium only, than in all other groups (p < 0.003), although in all active groups, the number was greater than the control. Total mast cell number was significantly higher with rocuronium and low-dose sugammadex compared with low-dose sugammadex only. The number of tryptase-positive mast cells with rocuronium only was significantly higher than in all other groups (p < 0.003). Tryptase-positive mast cell numbers in both groups receiving both rocuronium and sugammadex were significantly higher compared with both groups receiving sugammadex only. Rocuronium increased mast cell numbers, and degranulation was mitigated by sugammadex. These results suggest that sugammadex may be beneficial in treatment of rocuronium-induced anaphylaxis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
