Background Peripheral perfusion index (PPI) is associated with hypoperfusion in critical patients. Many researches focus on using PPI as a predictor in septic shock, but few studies report on its significance in surgical patients. We performed this study to find out association between PPI and surgical patients’ prognoses. Methods It’s a retrospective study from January to June 2019, on surgical patients transferred to ICU, Xinyang Central hospital, Henan province, China. The inclusive/exclusive criteria are followings, inclusive:1) age ≥18 years old; 2) surgical length ≥120min; Exclusive: 1) died in ICU; 2) discharging against medical advice; 3) existing diseases affecting blood flow of upper limbs, for example, vascular thrombus in arms; 4) severe liver dysfunction Patients were grouped according to their length of ICU stay (LOS ICU, >48h regarded as prolonged ICU stay, otherwise non-prolonged). Baseline characteristics (age, gender, comorbidity), surgical sites and length, SOFA and APACHE II on 1st day in ICU, LOS ICU, mean artery pressure (MAP), lactate clearance rate (LCR), peripheral perfusion index (PPI), temperature (axillary) were collected and compared between the 2 groups. Correlation and ROC (receiver operating characteristic) analysis was also performed. Results Eventually, 72 patients were included, 30 in prolonged and 42 in non-prolonged group. Compared to non-prolong, patients in prolonged ICU stay group had higher lactate(6h: 3.70±0.52 vs 2.50±0.59 mmol/L, p |
