Markers of inflammation as determinants of mortality in intensive care unit patients.

In this study, the investigators explored the relationship between mortality rate and serum levels of C-reactive protein (CRP), erythrocyte sedimentation ratio (ESR), albumin, and hemoglobin, leukocyte, and platelet counts of patients at the time of first admission to the intensive care unit (ICU). A total of 123 patients were admitted to 2 different ICUs. In the emergency departments, serum levels of CRP, ESR, and albumin and hematologic parameters of 81 patients who died and 42 patients who survived were compared. A Student t test and the chi2 test were used for statistical analyses. Mean CRP and ESR levels and leukocyte counts were higher in nonsurvivor than in survivor groups (P<.001 for all). Additionally, serum CRP and ESR elevations and leukocyte counts were determined to be individually related to mortality (P<.001, P<.05, and P<.05, respectively). The investigators concluded that initial serum levels of CRP and ESR and leukocyte counts can be used as determinants of mortality in ICU patients.

The comparison in terms of early complications of a new technique and percutaneous method for the placement of CAPD catheters.

BACKGROUND: Starting continuous ambulatory peritoneal dialysis (CAPD) immediately after insertion of a peritoneal dialysis catheter is essential in end-stage renal disease (ESRD). In relation to the insertion methods, various mechanical and infectious complications may arise. In this study, we aimed to compare early complications of the laparoscopic tunneling method of CAPD placement that we developed recently in order to minimize the complications, with those of the conventional percutaneous method. SUBJECTS AND METHOD: Included in this study were 12 consecutive patients with ESRD to whom we introduced catheters for CAPD by way of laparoscopic tunneling between April 2003 and July 2003 and followed up for at least 6 months, and 30 patients to whom the catheters were placed percutaneously in the same time period with the same follow-up time. The complications seen during the first 6 months after catheter placement with these two different methods were compared. RESULTS: In all of the subjects, dialysis was started soon after catheter placement. No peroperative morbidity was seen in any of the patients. While with laparoscopic tunneling method no mechanical problem was seen, the percutaneous method resulted in early leakage in 10%, pericatheter bleeding in 3.3%, and hernia in 3.3% of the patients. As infectious complications, peritonitis occurred as one episode/36 patient-months in laparoscopic tunneling and one episode/22.5 patient-months in percutaneous method; catheter insertion site infection was seen in none in the laparoscopic method, while one episode/90patient-months was seen with the percutaneous method. Tunnel infection did not arise in any of the subjects. CONCLUSION: The authors of this study think that the peritoneal tunneling method for introducing CAPD, which has been recently developed and began to be routinely used by them, is rather safe in terms of early complications.
