Abstract
PDF
- BACKGROUND
A randomized, multicenter, open-label, parallel group study was performed to compare the effects of remifentanil and morphine as analgesic drugs on the duration of weaning time from mechanical ventilation (MV).
METHODS
A total of 96 patients with MV in 6 medical and surgical intensive care units were randomly assigned to either, remifentanil (0.1-0.2 mcg/kg/min, n = 49) or morphine (0.8-35 mg/hr, n = 47) from the weaning start. The weaning time was defined as the total ventilation time minus the sum of controlled mode duration.
RESULTS
Compared with the morphine group, the remifentanil-based analgesic group showed a tendency of shorter weaning time (mean 143.9 hr, 89.7 hr, respectively: p = 0.069). Secondary outcomes such as total ventilation time, successful weaning rate at the 7th of MV day was similar in both groups. There was also no difference in the mortality rate at the 7th and 28th hospital day.
Kaplan-Meyer curve for weaning was not different between the two groups.
CONCLUSIONS
Remifentanil usage during the weaning phase tended to decrease weaning time compared with morphine usage.

Abstract
PDF
- BACKGROUND
We analyzed thyroid hormone values in brain death patients to determine the need for thyroid hormone replacement therapy.
METHODS
We analyzed 111 brain death donors (77 males and 34 females, mean age, 41.1 years (range; 8 months -72 years) in Ajou University Hospital from 2000 to 2010.
RESULTS
The mean values of thyroid hormones were T3; 72.5 ng/dl (normal range [NR] 60-181 ng/dl), T4; 5.0 microg/dl (NR 4.5-10.9 microg/dl), free T4 1.0 ng/dl (NR 0.8-1.5 ng/dl), and TSH 1.5 microIU/ml (NR 0.35-5.5 microIU/ml), respectively. However, the values of T4 (correlation coefficient -0.264, p = 0.005), free T4 (correlation coefficient -0.305, p = 0.001) and TSH (correlation -0.206, p = 0.031) significantly decreased based on the increase of interval from the brain death-inducing event to the evaluation time (hereafter, interval). The patients with greater than 8 days of interval (N = 30) showed significantly low thyroid hormone values compared to patients with less than 8 days of interval (N = 81); T3 (70.3 ng/dl vs. 77.0 ng/dl, p = 0.242), T4 (4.7 ng/dl vs.
5.3 ng/dl, p = 0.015), free T4 (0.8 ng/dl vs. 1.2 ng/dl, p = 0.006) and TSH (1.0 microIU/ml vs. 2.0 microIU/ml, p = 0.000), respectively.
CONCLUSIONS
As the intervals from the brain death-inducing events increased, all thyroid hormone values of brain death donors except T3 significantly decreased. Therefore, we recommend that careful consideration should be given to the interval from brain death-inducing event for the evaluation of thyroid hormone status of brain death patients.

Abstract

- BACKGROUND
Heart Rate Variability (HRV) is a valuable marker of autonomic tone and may assist evaluating the prognosis in patients with heart disease. The purpose of this study was to assess whether preoperative heart rate variability analysis predicts atrial fibrillation in patients undergoing coronary artery bypass graft (CABG) surgery. METHODS: This study was designed as a prospective observational study. After IRB approval was obtained by our institution, 76 patients scheduled for elective CABG surgery underwent a 10-min electrocardiogram recordings 1~2 hours prior to surgery. Heart rate variability analysis was performed with spectral analysis and point correlation dimension. RESULTS: There was no significant difference in the low and high frequency component (LF/HF) ratio preoperatively between patients with atrial fibrillation and patients with normal sinus rhythm postoperatively (3.0+/-2.45, 4.25+/-3.70, p=0.085). Baseline peak point correlation dimension (pPD2) was significantly higher in patients with atrial fibrillation than in patients with normal sinus rhythm postoperatively (4.2+/-0.8, 3.8+/-0.7, p=0.042). CONCLUSIONS: Patients who developed atrial fibrillation postoperatively had a higher baseline pPD2 value preoperatively. Point correlation dimensions may predict the occurrence of postoperative atrial fibrillation after CABG surgery. However, further studies are needed to confirm whether point correlation dimensions are an effective predictor for postoperative atrial fibrillation.
