Is 48 h a critical cut-off point for mortality in geriatric hip fractures?

Background/aim: In this study, our objective was to evaluate the mortality in geriatric hip fracture patients who were operated within 48 h after admission or after the 48thh. Materials and methods: A total of 194 patients who had undergone surgery for hip fracture between 2016 and 2018 were retrospectively evaluated. Patient information was obtained from the hospital's database using the ICD codes 81.52, 82.00­82.09, and 82.10. Radiological examination reports were collected from the patient files. Information on mortality was obtained from the Death Notification System of the Turkish Ministry of Health. First-year mortality rates of patients operated within 48 h (Group 1) and those operated at 48­96 h (Group 2) were compared. Results: The mean duration between admission to the hospital and surgical intervention was 33.90 ± 1.95 h (3­96 h). The mean total hospitalization time was 7.29 ± 1.53 days (2­36 days). Of the patients, 62 (32%) died within one year after the operation. The mean survival times for patients operated ≤48 h or >48 h were 8.47 ± 1.90 and 6.57 ± 2.59 months, respectively (Z = 1.074, P = 0.283). There was no significant correlation between survival time and the time delay before the operation (r = ­0.103, P = 0.153). Additionally, the Cox regression analysis, including age (years), ASA (grade 3 vs. 2), time to operation (h), and days spent in the ICU, demonstrated no significant independent effect of the time to operation on survival (P = 0.200). Conclusion: Although shortening the time to surgery may have some rationale, we did not find any difference in patients operated before 48 h compared to 48­96 h concerning mortality.

Predicting postoperative pain with neutrophil/ lymphocyte ratio after arthroscopic rotator cuff repair.

BACKGROUND: Postoperative pain is well known and usually disturbing complication of arthroscopic shoulder surgery. Inflammation plays an important role in the development and progression of postoperative pain. The aim of this study was to evaluate the predictability of postoperative pain through the correlation of neutrophil/lymphocyte ratio (NLR) with inflammation. In addition, the correlation of parameters such as operative time, tear size, age and gender with postoperative pain was evaluated. METHODS: Sixty three patients, who underwent arthroscopic rotator cuff repair, were evaluated in this single-center-based retrospective study. The American Society of Anaesthesiologists I and II risk groups were determined as the inclusion criteria. NLR was calculated using preoperative one day hemogram values in all patients. The amounts of analgesic use and Numerical Rating Scale (NRS) scores at the 12th, 24th and 48th hours and on the 3rd and 7th days were recorded. Multivariate linear regression analysis was used to correlate postoperative NRS scores with multiple independent factors, including preoperative NLR, sex, age, tear size, repair type, operative time, block time, postoperative analgesic intake and length of hospital stay. RESULTS: Sixty three patients with a mean age of 59.4 years (range, 40-72 years) were evaluated. The mean tear size was 2.8 cm (range, 1-5 cm), the mean operative time was 84.1 min (range, 35-135 min), the mean duration of block was 7.6 hours (range, 4-12 hours) and the mean length of hospital stay was 1.7 days (range, 1-3 days). There was no significant correlation between age, sex, tear size, repair type, operative time and postoperative NRS (p > 0.2). The preoperative NLR was found to be a strong predictor of postoperative NRS (p < 0.001, rho = 0,864). There was a correlation between the NLR and mean analgesic intake (p = 0,03). The duration of block was decreased in patients with a NLR above 2, while it was prolonged in patients with a NLR below 2 (p = 0.04, rho = -0,725). CONCLUSION: The preoperative NLR was found to be a strongest factor predicting high acute pain levels after arthroscopic rotator cuff surgery. Likewise, NLR was also predictive of postoperative block time and analgesic consumption.

Comparison of predictive powers of S100B and cell-free plasma DNA values in intensive care unit patients with intracranial hemorrhage.

PURPOSE: To investigate predictive powers of S100B and cell-free DNA (cfDNA) levels in patients in the intensive care unit (ICU) who have with intracranial hemorrhage (ICH) for prognosis. METHODS: Ninety-nine patients diagnosed with ICH were included in the study. The blood samples were drawn on the day of admittance to ICU and again on the third day. Duration of stay in the ICU and mortality were recorded. RESULTS: A positive correlation was determined between the values of S100B and cfDNA from both the analysis and the Acute Physiology and Chronic Health Evaluation II scores. For all patients, there was a positive correlation between the duration of stay in the ICU and the values of S100B and cfDNA on the third day. The levels of both S100B and cfDNA in patients who died in the ICU were significantly higher than of those who survived on the day of admittance. CONCLUSIONS: Both S100B and cfDNA values can be used as markers to predict the prognosis of ICU patients with ICH. However, S100B is more powerful for predicting the prognosis.
