To explore the influence of perioperative fluid management strategies based on the concept of injury control (DC) on the complications and prognosis of patients with multiple rib fractures accompanied by acute hemoppneumothorax.

A retrospective analysis was conducted on the clinical data of 80 patients with multiple rib fractures accompanied by acute hemopneumothorax admitted to our hospital from February 2023 to February 2025, including 52 males and 28 females. The age ranged from 24 to 75 years, with an average of (49.41±5.73) years. According to different nursing methods, they were divided into the DC group (n=43) and the control group (n=37). The control group was given traditional care, while the DC group was given care based on the DC concept on the basis of the control group. The 24-hour positive balance volume, central venous pressure (CVP), stroke volume variation (SVV), oxygenation index (PaO2/FiO2), complications and prognosis of the two groups of patients during the perioperative period were compared.

The levels of 24-hour positive equilibrium, CVP and SVV in the DC group were all lower than those in the control group, while the level of PaO₂/FiO₂ was higher than that in the control group (all P<0.05). The total incidence of complications during the nursing period in the DC group was 6.98%, which was lower than that in the control group (24.32%) (P<0.05). The mechanical ventilation time, ICU stay time and injury recovery time of patients in the DC group were all shorter than those in the control group (all P values <0.05). There was no statistically significant comparison of the 28-day mortality rate between the two groups (P>0.05).

Fluid management under the guidance of the DC concept can optimize the volume status of patients with multiple rib fractures accompanied by acute hemoppneumothorax, reduce the risk of complications, and improve the prognosis.
