[Evaluation of the information given to parents during the planned preanaesthetic consultation in a paediatric hospital].

INTRODUCTION: Information given to the parents of paediatric patients during the preanaesthetic consultation (CS) must be understandable. OBJECTIVE: We have studied the impact of this information given during CS. METHODS: Prospective study over four months with a questionnaire completed by parents after CS and before the hospitalization. The Sfar information booklet was given to the parents before CS. The study evaluated whether the information had been given ("have you received the information on...?"), understood ("Did you understand...?"), and if CS had influenced anxiety of parents/child; on four items of information, anesthetic risk, transfusion, postoperative pain, and anesthetic technique. The questionnaire noted also the parents sociocultural level (NSC), and if they had read the Sfar booklet. Statistical analysis (descriptive, uni-, multivariate), p<0.05. RESULTS: Four hundred questionnaires were distributed, 334 were analyzed. The information on the four items was considered to have been given in 75%, understood 72%, and to have diminished anxiety 68%. These results were not influenced by whether or not (88%) parents had read the Sfar booklet. How much information was given was a function of the physician giving the information. Elevated NSC and amount if information given improved comprehension optimized. Diminution of anxiety was when all four items were understood, CS was performed by a senior physician and the parent's NSC was high. DISCUSSION: Information better adapted to NSC may improve the quality of CS. The Sfar booklet does not contribute to parents understanding in this context.

[Impact of Cormack and Lehane's grade on Intubating Laryngeal Mask Airway Fastrach using: a study in gynaecological surgery].

OBJECTIVE: To evaluate the impact of Cormack and Lehane grade on the Intubating Laryngeal Mask Airway (LMA-Fastrach) using in women. STUDY DESIGN: Open prospective study. PATIENTS: The study included 115 scheduled gynaecologic surgery women. METHODS: An LMA-Fastrach was systematically performed in patients with a Cormack's grade > or =3 or when Arne's score was > or =7 whatever the Cormack. After induction of anaesthesia and neuromuscular blockade, Cormack's grade was assessed and LMA-Fastrach was inserted. Proper insertion was confirmed by the easiness of assisted ventilation and the normal aspect of the capnographic curve. Intubation through the LMA-Fastrach was carried out with the specific kit's endotracheal tube. More than two attempts were considered as a failure of the technique and an alternative method was performed. The following parameters were noted: age, weight, height, clinical predictors for difficult intubation (Arne et al.'s score), number of LMA-Fastrach insertion, ventilation efficiency through LMA-Fastrach, successful intubation with LMA-Fastrach and oesophageal intubation. RESULTS: Ventilation through the LMA-Fastrach was efficient in 97%. The success rate of intubation was 94.8% (86% on the first attempt). The success rate of ventilation and intubation were not statistically different according to the different Cormack's grades. The obesity (BMI>30) did not change the success rate of ventilation and intubation through the LMA-Fastrach. CONCLUSION: In women with either predicted or unpredicted difficult intubation, the success rates of ventilation and intubation through the LMA-Fastrach don't seem to be influenced by Cormack grade and obesity.

[Which propofol target concentration for ASA III elderly patients for conscious sedation combined with regional anaesthesia?].

OBJECTIVE: To determine the optimal propofol target concentration between 0.9-1.1 and 1.3 mg l(-1), for conscious sedation and amnesia using Diprifusor in ASA III patients over 60 years. STUDY DESIGN: Prospective study. PATIENTS AND METHODS: In ASA III patients over 60 years presented for elective vascular procedures under regional anaesthesia, sedation was induced with propofol TCI by increasing target concentrations from 0.9 to 1.3 mg l(-1) by 0.2 mg l(-1) steps up to a sedation score corresponding to light level (patient awakable with tactile stimulation). At baseline and each step, specific pictures were shown to the patient and clinical parameters and unwanted side effects occurrence were recorded. In PACU, memorisation of pictures and events was looked for. RESULTS: Conscious sedation was obtained in 100% of the patients at 0.9 mg l(-1), 94% at 1.1 and 78% at 1.3 mg l(-1). Amnesia was concentration-dependent and for each concentration was always more important for pictures than for events. Haemodynamic parameters did not change significantly. Incidents occurred in 12% of cases at 1.1 and 39.4% at 1.3 mg l(-1). DISCUSSION: None of those three concentrations was satisfying in 100% of cases for the three criterias (sedation < S2, amnesia and none side effects). These results suggest that propofol target concentration 0.9 microg ml(-1) could be used safely for sedation in elderly ASA III patients. Moreover, we have shown that amnesia for events requires higher propofol concentrations than amnesia for pictures during conscious sedation.

[Clonidine combined with flunitrazepam before carotid endarterectomy decreases cerebrovascular CO2 reactivity].

OBJECTIVE: Assess cerebrovascular CO2 reactivity changes using transcranial Doppler sonography (TCD) after oral premedication associating clonidine (2 micrograms.kg-1) and flunitrazepam (70 micrograms.kg-1) in patients scheduled for carotid stenosis surgery. STUDY DESIGN: Prospective study, not randomized, the patient being his own "control". PATIENTS AND METHODS: Thirteen patients undergoing carotid endarterectomy under cervical plexus block were included. The monitoring included: automated arterial pressure cuff, ECG, radial artery catheter, TCD with probe secured in temporal window. The study of the cerebrovascular CO2 reactivity was performed with TCD recording on the side of operation, on the day before, and on the day of carotid endarterectomy, 90 min after the premedication, immediately before surgery. To change PaCO2, four ventilatory states were successively performed: (1) normoventilation, (2) hyperventilation, (3) hypoventilation, (4) "breath-holding test". At each state, it was noted: HR, MAP, PaCO2, mean blood flow velocity in the middle cerebral artery (Vm-MCA), resistance index of Pourcelot (RI), cerebrovascular reactivity (slope Vm-MCA/PaCO2). The results (+/- SEM) were analyzed by Wilcoxon test or t test. RESULTS: After premedication, cerebrovascular CO2 reactivity decreased (0.043 +/- 0.019 vs 0.034 +/- 0.013; p < 0.05) without modification of RI (0.578 +/- 0.291 vs 0.612 +/- 0.025; NS). No complication during carotid clamping was reported. CONCLUSION: Inclusion of clonidine in premedication before carotid stenosis surgery must be questioned because a decrease of cerebrovascular CO2 reactivity could be deleterious in case of intraoperative stroke.

[Septic shock caused by Pasteurella multocida in alcoholic patients. Probable contamination of leg ulcers by the saliva of the domestic cats].

BACKGROUND: Pasteurella multocida septicemic septic shock without scratches in chronic alcohol abusers are rare and paucibacillar. Chronic legs ulcers could be predisposing factors. Three severe cases of such diseases with early multiple organ failure without endocarditis despite 3, 5 and 3 positive blood cultures respectively are reported. CASE REPORTS: In all three cases, the source of septicemia was extensive skin legs ulcers contaminated by domestic cat saliva, probably. The underlying diseases were alcoholism, without cirrhosis (2 cases) and with cirrhosis (1 case). Aggravating factors were present (chronic renal insufficiency, diabetes mellitus, non-steroidal anti-inflammatory agents) and they might have been responsible for pejorative outcome despite early appropriate empirical antibiotic regimens. DISCUSSION: Because P. multocida SSC could be fulminant in chronic alcohol abusers with or without cirrhosis, we propose for these patients reducing exposure to cats and hand-washing after exposure if wounds are present.

[Microbial infection documented on admission to the intensive care unit for post-chemotherapy neutropenia after empiric antibiotic therapy].

OBJECTIVE: The purpose of this study was to determine whether a systematic strategy of multiple microbiological samples for all adult patients with neutropenia admitted to an intensive care unit could document sepsis despite prior empiric antibiotic therapy. PATIENTS AND METHODS: All adults admitted to the intensive care unit with chemotherapy-induced neutropenia (WBC < 500/mm3) were included in the study. Microbiological samples were systematically obtained in all patients: 6 blood, 1 stool, 1 urine, 1 nasal swab. Data were analyzed for 54 consecutive patients: 22 men, 32 women, 42 with hematology diseases and 12 with solid tumors, mean age 46.6 +/- 14.4 years. Assessment of disease severity showed: simplified gravity index = 256 +/- 17; organ system failure score on day 1 = 2.42 +/- 1.1; 26 cases of septic shock among 47 cases of sepsis. Mortality was 50%. Within 48 h, bronchioalveolar lavage samples were obtained in 48 patients, and there were 12 spinal taps, 3 laparotomies, 3 skin biopsies and 6 sinus punctures. RESULTS: A microorganism was isolated in 39 patients (70%): 12 Gram negative, 12 Gram positive, 11 mycoses, 3 cases of herpes. Positive cultures were found for 31 blood, 1 bronchioalveolar lavage, 2 surgical, 5 serous and 22 oral or digestive tract samples. Documented microbial infection did not have prognostic value. Septic shock at admission was predictive of poor outcome. DISCUSSION: Despite prior antibiotic therapy in 46 patients, with a theoretically active drug in 37 cases, a systematic strategy of multiple deep samples increased the number of documented cases of infection in neutropenic patients. Oral and digestive tract infections predominated despite selective decontamination of the digestive tract.

[Septic shock with coma revealing typhoid fever].

BACKGROUND: Typhoid fever may be difficult to distinguish from malaria. Septic shock, encephalopathy and leukopenia are common features of both diseases. CASE REPORT: A 20-year-old South Korean woman was admitted to the intensive care unit with coma and shock. Vomiting and abdominal pain were followed by headache, prostration, fever and diarrhea. Leukocytopenia, lymphocytopenia, thrombocytopenia, rhabdomyolysis and hepatitis were present. Clotting tests were normal. The thick peripheral blood film was negative. Salmonella typhi was isolated from 6 blood cultures. Treatment associated ceftriaxone 4 g per day for 5 days, colloid and crystalloid fluids and dopamine. The patient was discharged 2 weeks later. DISCUSSION: Typhoid fever should be considered as a diagnosis in patients with sepsis who come from endemic zones. Abdominal symptoms, prolonged fever, coma and delayed headache are particularly contributive signs. Specific treatment should be instituted.

[Losing consciousness: role of the venous lactate levels in the diagnosis of convulsive crises].

OBJECTIVES: This prospective study was conducted to evaluate the usefulness of venous lactate assay in the diagnosis of generalized seizures. PATIENTS AND METHODS: Over a three month period, 78 consecutive adults admitted to the emergency unit for unconsciousness were included in the study. Three study groups were defined: patients with generalized seizures (n = 22), unconscious patients without seizure (n = 34) and known epileptic patients with unexplained malaises (n = 22). Patients with a disease susceptible of increasing lactate levels were excluded. Peripheral venous blood was drawn to determine lactates, bicarbonates and pH on a blood gas analyzer. All determinations were performed within 5 minutes of blood withdrawal. CPK level was also determined with an enzymatic method. RESULTS: In patients who had seizures, venous lactate levels were higher than those in patients who had no seizures: 4.3 +/- 0.5 mmol/l in generalized seizure patients versus 1.64 +/- 0.1 and 2.2 +/- 1.39 in unconscious patients without seizure and known epileptic patients with unexplained malaise respectively. The threshold lactate level of 2.5 mmol/l given by ROC curves gave a 0.97 specificity and a 0.73 sensitivity. DISCUSSION: The acidosis observed in patients with generalized seizures results from the combined effects of respiratory and metabolic acidosis. High lactate level would be a consequence of hypoxemia, per seizure rise in catecholamines, and aerobic and anaerobic metabolism in muscles during the tonic-clonic phase. In patients presenting in an unconscious state, increased lactate levels, even when determined up to 2 hours after venous blood withdrawal, could be a useful parameter for the diagnosis of epileptic seizure.
