A prospective study on the user-friendliness of four anaesthesia workstations.

BACKGROUND AND OBJECTIVES: Unlike for intensive care unit and home mechanical ventilators, no study has evaluated the user-friendliness of the recently introduced new anaesthesia workstations. METHODS: We performed a prospective study to evaluate the user-friendliness of four anaesthesia workstations, which were categorized into two groups: first-generation (Kion) and second-generation (Avance, Felix and Primus). Twenty users (12 nurse-anaesthetists and 8 anaesthesiologists) from three different anaesthesia departments at the same univeristy hospital participated in the study. The user-friendliness scale evaluated 10 criteria, including two design and monitoring criteria, four maintenance criteria and four ventilation use criteria. Each criterion was evaluated from 0 (poor) to 10 (excellent). RESULTS: The mean score obtained for the first-generation workstation was lower than those obtained for the three second-generation workstations (P < 0.05). No significant differences in the overall user-friendliness score was observed for the three second-generation workstations. The first-generation workstation obtained a significantly lower score than the three second-generation workstations for the design criteria (P < 0.01). For the screen criteria, the highest score was obtained by Felix, which has the largest screen and associated characters. For the main maintenance criteria, Kion and Felix obtained the lowest scores. No significant differences between the four anaesthesia workstations were found for only three of the user-friendliness criteria (self-test, alarms and settings). CONCLUSIONS: Anaesthesia machines have benefited from considerable advances in design and technology. This novel user-friendliness scale revealed that the most recent workstations were more appreciated by users than the first-generation of anaesthesia workstations. This user-friendliness scale may help the anaesthetic staff to 'consensually' choose the future workstation for their anaesthesia department.

[Postoperative pneumonia: nosocomial, predictable, iatrogenic, preventable or not?]. / Pneumonie postopératoire: nosocomiale, iatrogène, prévisible, évitable ou non?

We report the case of a 52-year-old man, ASA 3-4, malnourished, heavy smoker and drinker at the stage of chronic obstructive pulmonary disease and cirrhosis. The postoperative course of a cervical cancer surgery was complicated by a pneumonia with fatal outcome in the intensive care unit. Taking into account the patient's history and surgical requirements, this nosocomial infection did not appear easily preventable. The multiple risk factors and the few preventive measures usable were analyzed. In this context, the media and legal trend to make the doctors responsible for the nosocomial infections should be revised.

[Validation of the french translated Richmond vigilance-agitation scale]. / Validation de l'échelle de vigilance-agitation de Richmond traduite en langue française.

OBJECTIVE: To test reliability of the Richmond Agitation Sedation Scale (RASS) after French translation. STUDY DESIGN: Prospective psychomotor evaluation study. PATIENTS AND METHODS: Two bilingual physicians performed the translation from English to French language. The French version was then translated to English by a bilingual non physician ("backtranslation") and compared to the original version. The translated scale was tested according to usual guidelines concerning the translation of neuropsychological evaluation tools. The French version of RASS was tested on the morning of every fifth or sixth day, and 30-min after any procedure, in 43 consecutive patients admitted to a 12-bed medical-surgical intensive care unit during two months, by a group of four observers: the principal investigator, two anaesthesiology residents and one pharmacology student. Inter-rater reliability was tested using the simple and weighted Kappa coefficients (with their 95% confidence interval). A consensual and detailed "operating instructions" guide of RASS, intended for medical and nursing staff, has been added in the Annexe section. RESULTS: Four hundred twenty measures were performed during 105 grouped observations. Reliability of the French version of RASS was substantial. Simple Kappa coefficient, testing the concordance between observers, was ranged from 0.72 (0.62-0.81) to 0.87 (0.79-0.94) and weighted Kappa coefficient from 0.95 (0.92-0.98) to 0.99 (0.98-0.99). CONCLUSIONS: The French translation of RASS was acceptable. The translated scale preserved substantial inter-rater reliability. Monitoring of vigilance status in intensive care settings can be performed with this reliable clinical tool.

[General practitioners' and intensivists' relationships: intensivists' point of view from eight French southern regional areas]. / Relations entre médecin traitant et médecin réanimateur: l'opinion des réanimateurs de huit départements du sud de la France.

OBJECTIVES: Assessment of relationship between general practitioners and intensivists. STUDY DESIGN: Intensivists were questioned by phone from June 14th to September 28th 2004. METHODS: 245 out of 264 intensivists from 8 French Southern regional areas were questioned concerning their relationship with critically ill patients' general practitioner. RESULTS: Patients were mainly admitted into Intensive care Unit (ICU) from the Emergency Department (55%). An information letter from the general practitioner was reported for 20% of admitted patients but 50% of these letters was assumed as not informative. The informations concerning the patient's medical history, therapies, and disease leading to admission and the patient's status were assessed with 6.5, 7.0, 6.0 and 2.0, respectively (maximal note=10). The intensivists contacted the general practitioner for 30% of admitted patients. During the stay in ICU, 33% general practitioners were reported to request informations by phone or visit in ICU. When the stay in ICU was>10 days, the general practitioner was nearly never regularly informed about patient's status. When the patient was discharged from the ICU, 80% of intensivists used an exhaustive typed report to inform the general practitioner. The overall relationship between the general practitioner and the intensivist was assessed as 5.5/10. Insufficient information in the general practitioner's letter at admission, the lack of request for information during the stay in ICU, the lack of contact with the general practitioner by the intensivist and an intensivist's age between 46 and 55 were associated with a relationship assessment<4/10).

Pneumocystis carinii infection of bone marrow in patients with malignant lymphoma and acquired immunodeficiency syndrome. Original report of three cases.

Pneumocystis carinii (PC) pneumonia was reported with increased frequency in patients presenting with acquired immunodeficiency syndrome (AIDS) or in patients receiving immunosuppressive chemotherapy for hemopathies. Extrapulmonary dissemination of PC is rare. In this study, three patients had PC infection of the bone marrow. Two of them presented with malignant lymphoma that had apparent immunosuppression, and the third patient presented with AIDS. In all three cases, such an infection was observed before or concomittantly with PC pneumonia. A bone marrow biopsy, bone marrow aspirate, or both can be useful, readily available tools for the diagnosis of a PC infection and especially its dissemination in patients with malignant lymphoma after intensive treatment or in patients with AIDS. The appreciation of such a dissemination may have some implications in the treatment of PC infection.

[Catheter-related infections: how to reduce the risk?]. / Infections sur cathéter: comment réduire l'exposition au risque ?

Subcutaneous tunnelling of short-term catheters and the choice of site of catheter insertion are the two factors which influence the risk of catheter-related infection. Catheters inserted into a femoral vein have been associated with a higher risk of infection than those inserted into a subclavian vein. However, a meta-analysis comparing the internal jugular and subclavian sites did not report any difference. Regarding tunnelling, two randomized studies showed a benefit in terms of infection rates for the jugular and femoral sites when the blood sampling was not performed via the catheters. For the subclavian site tunnelling does not seem to bring any advantage compared to conventional insertion.

[Peripheral neurolytic blocks and spasticity]. / Spasticité: intérêt du testing par anesthésie locorégionale et blocs thérapeutiques.

Peripheral nerve blockade is one of the therapeutic possibilities to treat spasticity of various muscles. Percutaneous nerve stimulation allows accurate location of nerves and neurolysis can be performed using intraneural injection of 65% ethanol or 5 to 12% phenol. Spastic contraction of various muscle groups is a common source of pain and disability which prevents from having efficient rehabilitation. Test-blocks as well as neurolytic blocks are possible in most of motor nerves of the upper and lower limbs and main indications are spastic sequelae of stroke and spinal trauma but also of multiple sclerosis, cerebral palsy and chronic coma. The use of percutaneous nerve stimulation allows accurate location and four nerves are more frequently treated: pectoral nerve loop, median, obturator and tibial nerves. In patients with spasticity of the adductor thigh muscles, nerve blocks are performed via a combined approach using fluoroscopy and nerve stimulation to identify the obturator nerve. No complications occurred and minor side effects are transient painful phenomena during injection. These approaches proved to be accurate, fast, simple, highly successful and reproducible. Percutaneous neurolytic procedures should be done as early as possible, as soon as spasticity becomes painful and disabling in patients with neurological sequelae of stroke, head trauma or any lesion of the motor neuron.

Clinical application of ropivacaine for the lower extremity.

Ropivacaine is a new amide local anaesthetic, which is the first commercially available in its category as a pure S-(-) enantiomer. In most recent studies, ropivacaine exhibited a very close pharmacodynamic profile to equipotent doses of bupivacaine. Concentrations of 0.5%, 0.75% and 1% (5, 7.5 and 10 mg/mL, respectively) ropivacaine are used for intraoperative anaesthesia, while the concentration of 0.2% (2 mg/mL) is preferred for postoperative analgesia, either alone or in combination with opioids and/or clonidine. Ropivacaine is responsible for excellent postoperative analgesia following epidural and peripheral perineural injections, using single-shot injections and continuous infusions. Differential sensory/motor block is only apparent at low concentrations (0.2% and less). A significant amount of recent literature focuses on its use for peripheral blocks of the lower limbs, i.e. sciatic and femoral nerve blocks. The primary benefit of ropivacaine is its lower toxicity, mainly lower cardiotoxicity, following accidental intravascular injection. This higher therapeutic index leads to an improved safety profile as compared with potent local anaesthetics such as racemic bupivacaine. For that reason, ropivacaine is a good choice for both intraoperative and postoperative regional anaesthesia and analgesia.

Multiple-dose pharmacokinetics of pefloxacin in patients with hepatocellular deficiency.

Multiple-dose pharmacokinetics of pefloxacin were evaluated in 25 patients with hepatocellular insufficiency. The severity of liver disease was graded A, B or C according to the Child-Pugh classification. Pharmacokinetic parameters evaluated in patients on day 1 of treatment were compared with those computed in 11 healthy volunteers (the control group) after a single dose. Blood samples were taken at frequent intervals after drug administration and assayed by high performance liquid chromatography. The mean age of patients with liver impairment was slightly greater (59.5 years, range 33 to 81 years) than that of the control group (46.7 years, range 42 to 51 years). In the patients with liver disease, the mean (+/- SD) half-life of elimination, although highly variable, was significantly longer (46.3 +/- 42.5 hours) than in the control group (11.3 +/- 3.5 hours, p < 0.001). The total clearance was significantly decreased (1.76 +/- 1.31 L/h vs 6.03 +/- 2.99 L/h in the control group). In groups B and C of the Child-Pugh classification, total body clearance was about 30% of normal values. Elimination half-life increased by 200% in group B and 373% in group C compared with values in healthy volunteers. Intergroup differences (group B vs group C of the Child-Pugh classification) were not statistically significant. The minimum concentrations inhibiting 90% of Gram-negative strains (MIC90) were exceeded by plasma pefloxacin concentrations throughout treatment. For most patients, trough plasma concentrations were above 2 mg/L and peak plasma concentrations averaged 8.5 mg/L. Large inter- and intraindividual variations in the elimination half-life, total clearance and volume of distribution were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical pharmacokinetics during continuous haemofiltration.

Continuous haemofiltration is an extracorporeal technique that is increasingly used to remove fluid, electrolytes, and other waste products from the blood supply of critically ill patients with acute renal failure. Continuous arteriovenous haemofiltration (CAVH), where the blood exits the body from an artery and re-enters through a vein, is widely used. Continuous venovenous haemofiltration (CVVH), where blood both exits and enters through a vein by way of a mechanical pump, avoids problems that result from the variable ultrafiltration rate found during CAVH. Continuous arteriovenous or venovenous haemodiafiltration (CAVHD or CVVHD) combine continuous haemofiltration and haemodialysis. All methods involve ultrafiltration of the patient's blood through a filter that is highly permeable to water and small molecules. Drug elimination by haemofiltration depends mainly on the rate of ultrafiltration, the drug protein binding and the sieving coefficient of the membrane. Because patients undergoing continuous haemofiltration have impaired renal function, dosage reduction is often recommended so that adverse drug reactions are avoided. In contrast, if drug removal by haemofiltration is significant, dosage supplementation may be required to ensure therapeutic efficacy of the drug. Therefore, knowledge of the impact of continuous haemofiltration on drug elimination and the pharmacokinetic profile of drugs is essential to good clinical management. The currently available information on the clinical pharmacokinetic aspects of drug therapy during continuous haemofiltration are summarised. Drugs commonly associated with haemofiltration therapy are tabulated with updated pharmacokinetics and drug-monitoring information.

Intravenous nicardipine for severe hypertension in pre-eclampsia--effects of an acute treatment on mother and foetus.

OBJECTIVES: To assess the efficacy in lowering blood pressure, and the safety for mother and foetus of an acute nicardipine therapy in severe pre-eclampsia. DESIGN: Prospective clinical study. SETTING: One university hospital obstetric unit. PATIENTS: Twenty consecutive adult pre-eclamptic patients with severe hypertension. INTERVENTION: Nicardipine, 1 microgram/kg per min, was given intravenously to lower the mean arterial pressure (MAP) by at least 15%. Then, the dosage was reduced by 1/3, and the final dosage was determined to maintain MAP at 20-30% below the initial value, by increasing or decreasing the infusion rate by 0.5 mg/h. MEASUREMENTS AND RESULTS: Maternal MAP and heart rate (HR) were assessed every 5 min for 1 h. Foetal HR (FHR) was recorded throughout the study period and assessed for Fischer score. Gestational age, Apgar scores, birth weight, capillary filling time and the duration of stay in the paediatric intensive care unit (ICU) were used to evaluate the short-term perinatal outcome. A 15-30% decrease in MAP occurred within 15-20 min in all patients. An increase in HR was noted, and two patients had severe tachycardia. Maternal side effects included flushing, headache, nausea and dizziness. FHR showed a transient decrease in acceleration episodes and occurrence of decelerations. No nicardipine-related foetal distress occurred. Four infants born during the study period did well at birth and had a good outcome. CONCLUSIONS: Acute nicardipine therapy can induce severe maternal tachycardia. No severe foetal or neonatal adverse effects occurred. This dose scheme requires comparison with alternative therapeutic options.

CO assessment by suprasternal Doppler in critically ill patients: comparison with thermodilution.

OBJECTIVE: Comparison of suprasternal Doppler (SST) and thermodilution (TD) for the measurement of cardiac output (CO) in critically ill patients. DESIGN: Prospective study. SETTING: Intensive care unit of a university hospital. PATIENTS AND PARTICIPANTS: 65 consecutive critically ill patients requiring a pulmonary artery catheter. INTERVENTIONS: Paired CO measurements were made simultaneously using SST and TD by two independent operators. The time to obtain a CO value by SST was measured. Correlation coefficients and the linear regression equation were determined. A Bland and Altman diagram was plotted. A Bland and Altman diagram was also plotted for the level of cardiac index (CI) values (low: CI < 2.5 l min(-1) m(-2); normal: 2.5 < or = CI < or = 4.5 l min(-1) m(-2); high: CI > 4.5 l min(-1) m(-2)). MEASUREMENTS AND RESULTS: In seven patients SST failed to measure CO. In the remaining 58 patients 314 paired CO measurements were performed. The mean time to measure CO by SST was 73 +/- 45 s. The equation of linear regression was: SST(CO) = 0.84 TD(CO) + 1.39. The correlation coefficient was 0.84. The bias between SST and TD was -0.2 +/- 1.4 l min(-1). Biases were -0.23 +/- 0.50, -0.20 +/- 0.68, and 0.25 +/- 0.92 l min(-1) m(-2) for low, normal, and high levels of CI, respectively. CONCLUSION: SST does not accurately measure CO but allows a rapid assessment of CI level in critically ill patients.

Temperature measurement in intensive care patients: comparison of urinary bladder, oesophageal, rectal, axillary, and inguinal methods versus pulmonary artery core method.

OBJECTIVE: Comparisons of urinary bladder, oesophageal, rectal, axillary, and inguinal temperatures versus pulmonary artery temperature. DESIGN: Prospective cohort study. SETTING: Intensive Care Unit of a University-Hospital. PATIENTS: Forty-two intensive care patients requiring a pulmonary artery catheter (PAC). INTERVENTION: Patients requiring PAC and without oesophageal, urinary bladder, and/or rectal disease or recent surgery were included in the study. Temperature was simultaneously monitored with PAC, urinary, oesophageal, and rectal electronic thermometers and with axillary and inguinal gallium-in-glass thermometers. Comparisons used a Bland and Altman method. MEASUREMENTS AND MAIN RESULTS: The pulmonary arterial temperature ranged from 33.7 degrees C to 40.2 degrees C. Urinary bladder temperature was assessed in the last 22 patients. A total of 529 temperature measurement comparisons were carried out (252 comparisons of esophageal, rectal, inguinal, axillary, and pulmonary artery temperature measurements in the first 20 patients, and 277 comparisons with overall methods in the last patients). Nine to 18 temperature measurement comparisons were carried out per patient (median = 13). The mean differences between pulmonary artery temperatures and those of the different methods studied were: oesophageal (0.11+/-0.30 degrees C), rectal (-0.07+/-0.40 degrees C), axillary (0.27+/-0.45 degrees C), inguinal (0.17+/-0.48 degrees C), urinary bladder (-0.21+/-0.20 degrees C). CONCLUSION: In critically ill patients, urinary bladder and oesophageal electronic thermometers are more reliable than the electronic rectal thermometer which is better than inguinal and axillary gallium-in-glass thermometers to measure core temperature.

Training is required to improve the reliability of esophageal Doppler to measure cardiac output in critically ill patients.

OBJECTIVES: Assessment of and effect of training on reliability of esophageal Doppler (ED) versus thermodilution (TD) for cardiac output (CO) measurement. DESIGN: Prospective study. SETTING: Intensive care unit of a university hospital. PATIENTS: 64 consecutive critically ill patients requiring a pulmonary artery catheter, sedation, and mechanical ventilation. INTERVENTIONS: Esophageal Doppler CO measurements were performed by the same operator, whereas TD CO measurements were carried out by other independent operators. A training period involving the first 12 patients made the operator self-confident. In the remaining patients, the reliability of ED was assessed (evaluation period), using correlation coefficients and the Bland and Altman diagram. Between training and evaluation periods, correlation coefficients, biases, and limits of agreement were compared. MEASUREMENTS AND RESULTS: During training and evaluation periods, 107 and 320 CO measurements were performed in 11 out of 12 patients and in 49 out of 52 patients, respectively. Continuous CO monitoring was achieved in 6 out of 11 patients and in 38 out of 49 patients during training and evaluation periods, respectively. Between the two periods, correlation coefficients increased from 0.53 to 0.89 (p < 0.001), bias decreased from 1.2 to 0.1 l x min(-1) (p < 0.001), and limits of agreement decreased from 3.2 to 2.2 l x min(-1) (p < 0.001). CONCLUSION: A period of training involving no more than 12 patients is probably required to ensure reliability of CO measurement by ED.

Risk factors of failure and immediate complication of subclavian vein catheterization in critically ill patients.

OBJECTIVE: To identify the risk factors of failure and immediate complication of subclavian vein catheterization (SVC). DESIGN: Prospective observational study. SETTING: Surgical critical care unit of a tertiary university hospital. PATIENTS: Critically ill patients requiring a first SVC. INTERVENTION: Subclavian vein catheterization was attempted in 707 patients without histories of surgery or radiotherapy in the subclavian area. Failed catheterizations, arterial punctures, pneumothoraces and misplacements of the catheter tip were recorded. Risk factors of failure and immediate complication were isolated among patients' characteristics, procedure parameters (side and number of venipunctures) and the operator's experience using a univariate +/- multivariate analysis. MEASUREMENTS AND MAIN RESULTS: Five hundred sixty-two SVCs (79.5%) were achieved without adverse events. Among the remaining 145 catheterizations, 67 (9.5%) failures, 55 (7.8%) arterial punctures, 22 (3.1%) pneumothoraces and 30 (4.2%) misplacements of the catheter tip occurred. More than one venipuncture was the only risk factor of failed catheterization [2 venipunctures, odds ratio =7.4 (2.1-26); >2 venipunctures, odds ratio =49.1 (16.8-144.1)]. More than one venipuncture and age 77 years or more were predictive of the occurrence of immediate complications [2 venipunctures, odds ratio =3.6 (1.8-7.0); >2 venipunctures, odds ratio =14 (7.7-25.3); age >or=77, odds ratio =1.8 (1.0-3.1)]. The operator's training was not predictive of failed catheterization or immediate complication. CONCLUSION: For SVC, more than one venipuncture is predictive of failed catheterization and immediate complication. Age 77 years or more was predictive of immediate complications.

A Weibull distribution model for intradermal administration of ceftazidime.

The pharmacokinetics of 1 g of ceftazidime administered intradermally was studied in seven healthy volunteers. The objective of the present study was to find the most appropriate mathematical model to describe the drug intake process. The concentration of ceftazidime in plasma was measured by HPLC. The disposition of the drug was described by a one-compartment pharmacokinetic model, with drug intake occurring by different processes: a zero-order process due to the administration and a first-order intake from the injection site to the systemic circulation. The Weibull model was considered as an approximation of the overall process. The mean Weibull parameters were td (time necessary to transfer 63% of the administered drug into the systemic circulation) of 2.75 +/- 0.75 h, and f (shape) of 1.04 +/- 0.15. The mean elimination half-life was 2.0 +/- 0.4 h. The area under the concentration versus time curve obtained in this study (139 +/- 46 mg.h/L) is very near to literature values reported after single intravenous doses of 1 g of ceftazidime, suggesting that the bioavailability of ceftazidime after intradermal administration may be approximately 100%. Moreover, the mean peak plasma concentration (37 +/- 16 mg/L) is in the same range as that reported in the literature after intramuscular administration of a single dose of 1 g.

Ultrasonic and histopathological correlations of deep focal hepatic lesions induced by stereotaxic Nd-YAG laser applications.

Thirty six deep focal hepatic lesions were induced in eleven piglets by means of an Nd-YAG laser. Laser shots of 80 W power and 10 s duration were used, the beam being transmitted through an echoguided stereotaxic handpiece. From day 0 to day 120, the animals underwent ultrasonographic and morphological controls. At lasering time an hyperechoic image--12-18 mm in diameter--appeared due to boiling of tissue water. During the twenty postoperative days the lesion core was an echo-free area due to tissue vaporization, surrounded by an hyperechoic ring of increasing fibrosis, containing neovascularization and biliary ductules, while the hypoechoic outer area represented the peripheral halo of edema. In the long term, hyperechoic structures--swollen fibrotic septa of homogeneous fibrotic network--invaded the lesion site confirming good healing.

[Evaluation of inguinal hernia management in ambulatory surgery]. / Evaluation de la prise en charge des hernies inguinales en chirurgie ambulatoire.

AIM: To evaluate the prospects of ambulatory surgery for inguinal hernia. PATIENTS AND METHODS: From January 1995 to June 2001, 599 operations on inguinal hernias were performed. Patients were composed of 554 men and 45 women. The average age was 58 years (7-95). All patients were examined by their primary doctor on the first and the third day, and by the surgeon on the 10th day. RESULTS: Four hundred and eighty-one patients were operated on by ambulatory surgery (80.3%). The "Tension-free" technique was carried out among 495 patients (82.6%). Loco-regional anaesthesia was used for 499 patients (83.3%). The postoperative rate of complications was 10.4% (62 patients). Only 201 patients presented postoperative painful symptomatology (33.6%), 341 a discomfort (56.9%), and 57 (10%) experienced no pain. The overall satisfaction rate was 92.9%. CONCLUSION: Use of the "Tension-free" technique under loco-regional anaesthesia for inguinal hernias allows ambulatory surgery with a low rate of complications and high satisfaction for the patients.

[Severe preeclampsia. Principal management modalities before patient transfer]. / Pré-éclampsie sévère. Principales modalités de la prise en charge avant transfert.

Preeclampsia is relatively frequent during pregnancy. The occurrence of complications implies referral to a specialized center for optimal care of both mother and fetus. The transfer of these patients is very critical with risk of worsening the mother's status. Management before referral aims to stabilize material clinical status, requiring precise clinical assessment, treatment of severe hypertension or pulmonary edema, and prevention or treatment of eclampsia. The management of oliguria and the tracheal intubation are associated with specific problems. Fetal wellbeing is assessed before and during emergency treatments of maternal disorders.

[Severe preeclampsia. Analysis of a case with fatal outcome]. / Pré-éclampsie sévère. Analyse d'un cas d'évolution fatale.

We report a case of preeclampsia presenting initially as a moderate hypertension, and complicated over a ten-day period by eclampsia, retinal hemorrhage, cerebral and hepatic subcapsular hematomas, HELLP syndrome, disseminated intravascular coagulation and renal failure. Fatal outcome was related to cerebral death and rupture of the liver hematoma. The case analysis points out inaccurate initial management: probable misdiagnosis of epigastric pain related to subcapsular hematoma, ineffective antihypertensive therapy, aspiration of the gastric content after benzodiazepine treatment of eclampsia, transfer of the patient without stabilisation of her clinical status.
