Objective To derive a prediction index based on the most salient history, laboratory and clinical parameters for identifying women at high risk of developing preeclampsia (PE) and to suggest a primary prevention. Material and method Non-pregnant women with a history of PE (n =101) were compared to non-pregnant parous women with a history of one or more successful normotensive pregnancies (n =50) but with comparable age, gestation and parity profiles. The parameters included history and clinical examination; laboratory studies (hemostasis, coagulation, vitamins); and morphological and functional tests (cardiovascular and renal functions). Stepwise logistic regression analysis was applied to develop a three step PE prediction index based on the most discriminant parameters. Strategies to prevent PE in the high-risk group are described. Results Identification of women at high risk of PE can be done efficiently (88% sensitivity and specificity) using a predictive index based on a simple history, laboratory, clinical and functional information. Stategies to prevent PE in our high-risk group have given encouraging results during next pregnancy. Conclusion Our study gives a predictive index of PE outside of pregnancy and possibilities to do a primary prevention. [less ▲]

This study aimed at investigating the Bispectral Index (BIS) profile during carotid cross clamping (CXC). The study involved a pilot group of 10 patients undergoing routine carotid endarterectomy with shunt insertion under total intravenous anesthesia, and a study group of 26 additional patients. In all patients, rates of propofol and remifentanil providing a steady-state level of hypnosis (BIS: 40-60) were maintained constant throughout a recording period ranging from 3 minutes before CXC to shunt insertion. BIS was recorded throughout this period and the internal carotid backflow observed at the time of shunt insertion was graded as good, moderate, or poor. In addition, A-Line Autoregressive Index (AAI) and processed electroencephalogram (EEG) parameters were recorded in patients of the study group. All parameters were averaged over I minute before CXC, at CXC, 1, 2, and 3 minutes after CXC, and at shunt insertion. Statistical analysis was performed using X 2, Friedman, and Spearman correlation tests. For technical reasons, reliable AAI, BIS monitor-derived, and other processed EEG data were obtained in 24, 25, and 18 patients of the study group, respectively. During the first 3 minutes after CXC, BIS increased over 60 [68.8 (6.1)] in 47%, decreased below 40 [34.9 (4.4)] in 25%, and remained in the 40 to 60 range in 28% of all recruited patients. A BIS increase was more frequently observed in patients with moderate or poor than in those with good internal carotid backflow (78, 67, and 29%, respectively). It was significantly correlated to an increase in AAI and EEG amplitude, a decrease in EEG suppression ratio, and a shorter time between induction of anesthesia and CXC. A BIS decrease was significantly correlated to an increase in suppression ratio and a longer time between induction and CXC. In conclusion, during CXC under a constant level of intravenous anesthesia, BIS may increase, decrease, or remain unchanged. The paradoxical BIS increase could be related to borderline ischemia, a change in brain anesthetic agent concentration, or a change in the nociceptive-antinociceptive balance associated with a CXC-elicited painful stimulation. Caution should be used when interpreting BIS value during CXC. [less ▲]

Background. The spectral entropy of the electroencephalogram has been proposed to monitor the depth of anaesthesia. State Entropy (SE) reflects the level of hypnosis. Response Entropy (RE), computed from electroencephalogram and facial muscle activity, reflects the response to nociceptive stimulation. We evaluated the effect of rocuronium on Bispectral Index (TM) (BIS) and entropy responses to laryngoscopy. Methods. A total of 25 patients were anaesthetized with propofol using a target-controlled infusion. At steady state, they randomly received 0.6 mg kg(-1) rocuronium (R) or saline (S). After 3 min, a 20 s laryngoscopy was applied. BIS, RE and SE were recorded continuously and averaged over 1 min during baseline, at steady state, 2 min after R or S administration (R/S+2) and 0, 1, 2 and 3 min after laryngoscopy (L0, L1, L2, L3). Results. At R/S+2, the RE-SE gradient was higher in Group S than in Group R. Laryngoscopy provoked an increase in BIS, RE and SE. Comparing R/S+2 and L0 values in Groups R and S, BIS increased from 43 (6) to 49 (8) and 42 (9) to 51 (15), SE increased from 43 (7) to 50 (8) and 41 (10) to 55 (12), and RE increased from 46 (8) to 54 (9) and 47 (12) to 66 (15), respectively. BIS and SE did not differ between groups. At L0, RE and RE-SE were higher in Group S [66 (15) and 11 (4), respectively] than in Group R [54 (9) and 4 (2), respectively]. Conclusions. Rocuronium alters the RE-SE gradient and the RE and RE-SE responses to laryngoscopy. Muscle relaxation may confound interpretation of entropy monitoring. [less ▲]

BACKGROUND: Dexamethasone prevents postoperative nausea and vomiting but may increase blood glucose. We compared blood glucose concentrations after dexamethasone in non-diabetic and type 2 diabetic patients undergoing surgery and looked for any association with preoperative glycosylated haemoglobin [HbA (1c)] and BMI. METHODS: Sixty three patients were enrolled: 32 were non-diabetic (Group ND) and 31 type 2 diabetic (Group D) without insulin treatment. Anaesthesia was induced using i.v. anaesthetic agents and maintained with sevoflurane. All patients received 10 mg dexamethasone at induction. Blood glucose concentrations were measured at induction and then every 60 min for 240 min. Data were analysed using anova. Effects of HbA (1c) and BMI were investigated using linear correlation and logistic regression. RESULTS: Blood glucose concentrations increased significantly over time and peaked at 120 min after 10 mg dexamethasone in both groups. The magnitude of increase was comparable between the groups [mean (SD) 29 (19) and 35 (19)% of baseline in Group D and Group ND, respectively]. Maximum concentrations were higher in Group D [8.97 (1.51) mmol litre(-1), range 6.67-12.94 mmol litre(-1)] than in Group ND [7.86 (1.00) mmol litre(-1), range 5.78-10.00 mmol litre(-1)]. There was a significant correlation between the maximum concentrations and BMI (R(2)=0.21) or HbA (1c) (R(2)=0.26). Logistic regression analysis revealed that the higher the BMI, the lower the HbA (1c) threshold associated with an increased probability (>0.5) of observing blood glucose levels higher than 8.33 mmol litre(-1) during 240 min after dexamethasone administration. Similarly, the higher the HbA (1c), the lower the BMI threshold associated with the same probability. CONCLUSIONS: After 10 mg dexamethasone, blood glucose levels increase in non-diabetic and type 2 diabetic patients undergoing abdominal surgery. Poorly controlled diabetes and severe obesity can influence the development of hyperglycaemia. [less ▲]

A lumbar epidural catheter placed for labor analgesia proved to be difficult to remove after an uneventful delivery. With the patient in the position of catheter insertion, i.e. seated, firm and steady traction allowed removal of the catheter and revealed a knot 4 mm from its tip. Passing excessive amount of catheter into the epidural space may have contributed to this complication. Guidelines to prevent and to minimize this complication are suggested. (c) 2005 Elsevier Ltd.
