A novel minimally invasive fixation method for flail chest management in a Canine model: an animal research

Table 1 Preoperative and Postoperative Measurements. Data was given as Mean ± S.D. with 95% confidence interval. P value was calculated using Independent-Samples T Test, and a P value less than 0.05 was considered to be statistically significant. Pre, Pre-anesthesia Measurements, RR, Respiratory Rate. PCO₂, Partial pressure of carbon dioxide. PO₂, Partial pressure of oxygen. SpO2, Saturation of Pulse Oxygen. HR, Heart Rate. Temp, Body Temperature. DS, Duration of Surgery. TBL, Total Blood Loss volume
