Multivariate regression analysis of factors related to appearance of irrigating solution uptake syndrome showed that only surgery time ≥60 minutes; online weight ≥60g; The amount of irrigating solution absorbed ≥1000 ml and the volume of irrigating solution used ≥ 30 liters are independent factors related to the occurrence of irrigating solution absorption syndrome in 3% sorbitol group; Not found in the 0.9% NaCl group (Table 3.25).
