This prospective study investigated the levels of procalcitonin (PCT) and C-reactive protein (CRP) in patients with various types and severity of multiple trauma, and their relationship to trauma-related complications. Adult multiple-trauma patients (n = 113) admitted to the intensive care unit (ICU) in the first 24 h after trauma were included. The Injury Severity Scores (ISS), and PCT and CRP levels were measured in the first 24 h (day 1), on day 7 and on the final day of their ICU stay. Survival at 30 days was recorded. Mean PCT and CRP levels were both significantly higher on day 7 compared with day 1 and the final assessment day in patients with an ISS > 20. Levels of PCT were significantly higher in cases with sepsis, severe sepsis or septic shock compared with cases who developed systemic inflammatory response syndrome (SIRS), however levels of CRP were significantly higher only in cases with severe sepsis or septic shock, but not in cases with sepsis alone. These data support the view that PCT levels may be a better indicator than CRP levels in the early diagnosis of septic complications in patients with multiple trauma.
Cardiopulmonary bypass (CPB) contributes to the secretion of anti-inflammatory cytokines that mediate the inflammatory response observed during open heart surgery. In addition to many factors, type of anesthesia management affects immune response and central nervous system in cardiac surgery. The aim of this study was to assess the effect of propofol versus desflurane anesthesia on systemic immune modulation and central nervous system on patients undergoing coronary artery bypass grafting. Forty patients undergoing elective coronary artery bypass graft surgery with CPB were included in this prospective randomized study. Patients were allocated to receive propofol (n = 20) or desflurane (n = 20) for maintenance of anesthesia. The blood samples for IL-6, IL-8, TNF-α, and S100β were drawn just prior to the operation before the induction of anesthesia, second before cardiopulmonary bypass, third after CPB, fourth 4 h postoperatively at the ICU. Major finding in our study is that S100β levels were lower in propofol group when compared to desflurane anesthesia. And also immune reaction was less in patients exposed to desflurane anesthesia when compared to propofol anesthesia as indicated by lower plasma concentrations of IL-8 and IL-6. Propofol is more preferable in terms of S100β for anesthetic management for CABG.
In pain control after laparoscopic cholecystectomy, subhepatic administration of bupivacaine immediately after the creation of pneumoperitoneum has been shown to be more effective than administration before the withdrawal of the trocars. We aimed to investigate the effect of intraperitoneal bupivacaine administration to the subhepatic area before the creation of the pneumoperitoneum. Eighty patients undergoing elective laparoscopic cholecystectomy under general anesthesia were included in a prospective, randomized study. Patients received 20 mL of 0.5% bupivacaine in the subhepatic area just after intubation, before pneumoperitoneum (group 1), immediately after the creation of the pneumoperitoneum (group 2), just before the removal of the trocars (group 3), or received no local anesthetic (group 4). The degree of the postoperative pain was assessed at 0, 4, 8, 12, and 24 hours after the surgery. The consumption of analgesics (diclofenac sodium) was also recorded. The pain scores and analgesic consumption did not differ among groups 1, 3, and 4. The pain scores of group 2 were lower at each time point compared to the other groups (P < 0.001). Postoperative analgesic consumption in group 2 was reduced compared to the other groups (23.4 +/- 35.9 mg vs. 80.0 +/- 66.3 mg, P = 0.005 [group 1], 69.6 +/- 62.2 mg, P = 0.026 [group 3], and 70.0 +/- 59.9 mg, P = 0.022 [group 4]). The subhepatic infiltration of 20 mL of 0.5% bupivacaine offers good postoperative analgesia when applied just after the creation of the pneumoperitoneum, not before the pneumoperitoneum or after the termination of the pneumoperitoneum.
The aim of this present study is to compare the effect of pressure-controlled ventilation and volume-controlled ventilation on pulmonary mechanics and inflammatory markers in prone position. The study included 41 patients undergoing to vertebrae surgery. The patients were randomized into two groups: Group 1 received volume-controlled ventilation, while group 2 received pressure-controlled ventilation. The demographic data, pulmonary mechanics, the inflammatory marker levels just after the induction of anesthetics, at the 6th and 12th hours, and gas analysis from arterial blood samples taken at the beginning and the 30th minute were recorded. The inflammatory marker levels increased in both groups, without any significant difference among groups. Peak inspiratory pressure level was higher in the volume-controlled ventilation group. This study revealed that there is no difference regarding inflammatory marker levels between volume- and pressure-controlled ventilation.
The application of low tidal volume + PEEP + high respiratory rate during laparoscopic surgeries may be considered to improve good results of arterial blood gases.
We concluded that respiratory mechanics were affected by desflurane with low flow anesthesia in patients undergoing laparoscopic abdominal surgery. No significant influence on respiratory mechanics was seen with sevoflurane anesthesia.
Comparison of entropy (state entropy [SE] and response entropy [RE]) with the bispectral index (BIS) during propofol sedation in monitored anaesthesia care (MAC) was carried out in patients undergoing hand surgery. Thirty candidates for elective hand surgery were pre-medicated with midazolam 0.06 mg/kg and atropine 0.01 mg/kg. Sedation was induced with intravenous propofol and fentanyl was also administered. The Modified Observer's Assessment of Alertness/Sedation Scale (MOAA/S) was used to determine sedation level and pain was maintained at < 4 on a 0 - 10 verbal rating scale. The BIS, entropy, MOAA/S and pain values were recorded before initiation of sedation (control), during initiation of sedation, during surgery, and for 30 min after the end of surgery and anaesthesia. On initiation of sedation, entropy decreased more rapidly than BIS. At 10 min after initiation of sedation, the mean +/- SD values for MOAA/S, BIS, RE and SE were 3.00 +/- 0.36, 85.45 +/- 0.15, 74.00 +/- 0.60 and 72.02 +/- 0.12, respectively. During recovery, BIS and RE and SE increased in parallel with MOAA/S. It is concluded that entropy monitoring is as reliable as BIS monitoring in MAC.
