Perturbations biologiques au cours des résections intra-utérines sous irrigation de glycocolle

Abstract

This study was carried out to assess the relations between plasma glycine concentrations and the biochemical changes occurring during intra-uterine resections (IUR) under glycine irrigation. Sixty patients with benign uterine conditions were included. They were all ranked ASA 1 or 2. The biological parameters were assessed before surgery (T0), at the end of surgery (T1) and 60 min afterwards (T2). They included the blood count and blood concentrations of sodium, potassium, chloride, proteins, bicarbonates, glucose, urea nitrogen, creatinine and glycine. Plasma osmolarity was calculated. The irrigation of the uterine cavity resulted in an increase of glycine concentrations (28 % of cases), and a decrease of sodium (22 % of cases), proteins and haematocrit (32 % of cases). Mean osmolarity remained unchanged. Blood glycine concentrations were directly correlated with the volume of irrigating solution, as well as with the duration of surgery. Protidaemia was inversely related to the blood glycine concentration. Multiparous patients had lower glycine concentrations than nulliparous patients. This was probably due to the uterine cavity being less compliant in the latter. On the other hand, there was no correlation with the uterine pathological condition. In this series, five cases of uterine perforation occurred with very large biological variations, especially a decrease in haematocrit and osmolarity. In these cases a clinical and biological water intoxication syndrome may occur as a result of large volumes of irrigating fluid passing into the peritoneal cavity.
