RESUMO
We report the case of a 97 year old woman suffering from a voluminous diverticle of the cervical esophagus with important comorbidities and a very poor quality of life. A diverticulectomy under general anesthesia implied a high level of risk. Regional anesthesia was chosen, i.e. an intermediate cervical plexus block, with mild sedation allowing to maintain contact with the patient. The procedure was carried out without complications and the patient's and surgical staff satisfaction were optimal.

This is the case report of a 16-year-old male who suffered major facial trauma in a road traffic accident (unhelmeted scooter rider against signpost). During prehospital care, he was stable and awake. He was admitted to the emergency room of our university hospital and rapidly transferred, in a sitting position and breathing spontaneously, to the operating room for emergent surgical tracheostomy under local anaesthesia and sedation. This procedure turned out to be difficult (sitting position, patient uncooperative) and ventilatory compromise led us to intubate the patient without difficulties: indeed, supraphysiological mouth aperture (due to multifocal mandible fractures) and presence of supraglottic bubbling under spontaneous ventilation facilitated intubation in spite of major oropharyngeal bleeding. This allowed rapid restoration of adequate ventilation and tracheostomy was performed under standard conditions without further problems. This case report confirms the superiority of orotracheal intubation under light sedation over emergent tracheostomy in this type of situation, as stated under the SFAR guidelines.

OBJECTIVE: To determine the level of satisfaction in terms of pain relief and comfort among patients receiving different postoperative analgesia protocols after hand surgery under regional anaesthesia in a day care unit. METHODS: Cohort study among patients after hand surgery under regional anaesthesia during two consecutive three months time periods, with patient stratification according to the expected pain level with different balanced analgesia protocols (group A: carpal tunnel, group B: other surgery without bone involvement, group C: bone surgery). A telephone survey, scoring analgesia and comfort, each with a numerical (0-10) scale was conducted on days 1 and 7. During the first period analgesia for groups A and B was the same (acetaminophen-dextropropoxyphene or acetaminophen-codeine) and group C patients were treated with acetaminophen-ketoprofen-tramadol. In the second period analgesia was reduced for group A (acetaminophen alone) and increased for group B (acetaminophen-ketoprofen-tramadol) and group C (duration increased from 3 to 7 days). RESULTS: For carpal tunnel surgery, analgesia with acetaminophen alone was efficient, (Pain scale [PS] d0=2[0-10], PS d1=1 [0-10] and PS d2-d4=0,5 [0-10]). This surgery does not elicit important pain, there is no benefit in adding other analgesics. For group B, a significant improvement in postoperative pain was observed (postoperative d1 p<0.03) with a major increase in side effects (2/57 vs 17/48 p<0.001). For group C, therapeutic changes were ineffective (PS d0=2 vs 3.5 et PS d1=3 vs 5 [NS]) and we noticed an increase in side effects (p<0.05). One third of all patients are totally satisfied on day 7, logistic regression showing the role of inefficient analgesia in late postoperative period (PS>2 between d2-d4). Between day 1 and day 7, 20% of the patients change their point of view, those who feel less satisfied on day 7 complained of a more severe postoperative pain between day 2 and 4 (p<0.001) and between day 5-7 (p<0.01). CONCLUSION: For hand surgery on day case, quality of late postoperative analgesia (day 2-day 7) is strongly related to patient's satisfaction on day 7.

BACKGROUND: Brachial plexus is usually approached by the supraclavicular or axillary route. A technique for selective blockade of the branches of the plexus at the humeral canal using electrolocation has recently been proposed. The aim of the present study was to assess the feasibility of this technique in the ambulatory patient and to determine the optimal sequence of nerve-blocking. METHODS: The nerves originating from the brachial plexus were located in the humeral canal, at the junction of the proximal and the middle third of the arm, with a stimulator and blocked using either lidocaine or a mixture of lidocaine and bupivacaine, depending on the anticipated duration of surgery. The minimal stimulating intensity eliciting an adequate response, type of local anaesthetic and injected volume, and time of onset of surgical anaesthesia were collected. RESULTS: The study included 503 consecutive ambulatory patients due to undergo surgery of the elbow, wrist or hand in one year. Suitable anaesthesia was obtained with the humeral blockade in 82.1% of cases. In the remaining 17.9%, an additional block at the elbow was required, mainly for ulnar and median nerves. The onset times of sensory blocks were the longest for the median nerve, similar for the radial and ulnar nerves, shorter for the musculocutaneous nerve and the shortest for the medial brachial and antebrachial cutaneous nerves. The difference was more significant with the lidocaine-bupivacaine mixture, than with lidocaine alone (P<0.001 vs P<0.05, respectively). The onset times of motor blocks were the longest for the median nerve (P<0.05) and the shortest for the musculocutaneous nerve (P<0.001). Neither nervous nor vascular complications occurred. CONCLUSION: This study shows that the nerve block at the humeral canal is an efficient and safe technique. Considering the onset times of nerve blocks, the following sequence for blockade can be recommended: median, ulnar, radial, musculocutaneous, medial (brachial and antebrachial) cutaneous nerves. The selective blockade of the main nerves of the upper limb at the humeral canal can be recommended for surgery of the forearm and the hand in the ambulatory patient.

The purpose of this study was to assess the value of lignocaine biotransformation into monoethylglycinexylidide (MEGX) and conventional liver function tests in the early post-operative period as an indicator of graft function and as a diagnostic tool for complications after hepatic transplantation. Monoethylglycinexylidide formation, plasma bilirubin, aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), factor V index (FVI) and prothrombin time index (PTI) were measured in 71 patients undergoing 80 liver transplantations respectively at 12 (T1), 24 (T2), 48 (T3) and 72 h (T4) after liver graft revascularization. Patients were divided into two group according to the post-operative outcome. Patients with favourable outcome (n = 59) had significantly higher monoethylglycinexylidide synthesis, higher factor V index and prothrombin time index plasma concentrations, lower bilirubin, ASAT and ALAT plasma concentration (P < 0.0001 at T2 and T3) than those with complicated time course (n = 21). Monoethylglycinexylidide synthesis was the best discriminant of a favourable outcome, whereas bilirubin and ALAT concentrations were associated with complications (bilirubin for primary non function [PNF], ALAT for acute rejection). Thus, the combination of parameters at T2 was a very efficient predictor of primary non function, acute rejection and an uncomplicated time course.

A wide variety of monitoring devices have been used for intracranial pressure measurement. The aim of this article is to present the most common devices and to assess their accuracy, stability and complications, with reference to current literature. Measurement with an intraventricular catheter remains, the reference method. However new techniques with distal measurement (fiberoptic or strain gauge) seem to be accurate, but have a higher cost. Some practical problems, such as the zero pressure reference level and the side of measurement, are also discussed.

This report describes the early diagnosis, due to an acute increase of jugular venous oxygen saturation occurring 20 hours after trauma, of a traumatic carotid-cavernous sinus fistula after severe head injury. Hyperemia in severe head injury should be treated only after an intracerebral arteriovenous communication has been excluded.

Thirty-six adult severe head injury and cerebral stroke patients in four intensive-care units were randomized to receive one of three enteral diets for 21 days. These diets, which supplied 45% of calories from fat, differed only in lipid composition. Diet A was comprised of 100% soybean oil, diet B contained a 50:50 (wt/wt) mixture of soybean oil and medium-chain triglycerides (MCTs), and diet C contained 42.5% MCT, 50% soybean oil, and 7.5% blackcurrant seed oils. Plasma phosphatidylcholine and fatty acid composition of plasma total phospholipids were determined before initiating treatment (day 0) and weekly throughout the study. Results indicated that at the start of the study, all patients had low linoleic acid (18:2 omega 6) levels compared with healthy subjects. Emulsion A disturbed the balance between several fatty acids of the omega 6 series, as exemplified by the significant increase in 18:2 omega 6 proportions. In contrast, both emulsions B and C introduced a less-pronounced rise in 18:2 omega 6 associated for emulsion C with a significant increase in dihomo-gamma-linolenic acid (20:3 omega 6) and docosapentaenoic acid (22:5 omega 3) in plasma phospholipids. Furthermore, 18:3 omega 6 change was significantly different between groups A and C and that of 20:3 omega 6 between group A and both groups B and C. Throughout the study, arachidonic acid (20:4 omega 6) exhibited remarkable steady-state levels regardless of the diet. This study shows that providing the injured body with high amounts of 18:2 omega 6 does not lead to high levels of its upper derivatives in plasma phospholipids.(ABSTRACT TRUNCATED AT 250 WORDS)

Fatty acid composition of phospholipids in red blood cell membranes was studied in 32 severely head-injured or cerebral stroke patients receiving enteral nutrition for 3 weeks. During this study the effects of three diets differing only by their lipid composition were investigated. The daily energy intake of each patient amounted to 2950 kilocalories, of which the lipid fraction represented 45.7%. Diet A contained only soybean oil, diet B consisted of a 50% soybean oil and 50% medium-chain triglycerides mixture, and diet C was an emulsion of 50% soybean oil, 42.5% medium-chain triglycerides, and 7.5% black-currant seed oil. Our results showed no biochemical signs of fatty acid deficiency in red blood cell membranes for the patients at the beginning of the study, after a comparison with a control group of 20 healthy adults. Inhibition of delta 6-desaturase activity on linoleic acid (C18:2 omega 6) after diet A was suggested by an increase of linoleic acid without a corresponding increase of dihomo-gamma-linolenic acid (C20:3 omega 6). Replacing 50% of soybean oil by with medium-chain triglycerides (diet B) prevented this enzyme inhibition. Supply of black-currant seed oil rich in gamma-linolenic (C18:3 omega 6) and stearidonic (C18:4 omega 3) acids (diet C) induced significant increases of dihomo-gamma-linolenic and eicosapentaenoic (C20:5 omega 3) acids, without influencing arachidonic acid (C20:4 omega 6) levels. This balance was evaluated through the ratio (C20:3 omega 6 + C20:5 omega 3)/C20:4 omega 6.

In order to assess the metabolic value of medium-chain triglycerides (MCT) in severely stressed intensive care unit patients, two fat emulsions containing either long-chain triglycerides (LCT), or a mixture of 50% MCT and 50% LCT were compared in 24 head trauma patients over a 10 day period. Variations of serum triglyceride, non-esterified fatty acid, glycerol and phospholipid concentrations remained comparable after both lipid infusions. Bilirubin, alkaline phosphatase and transaminase plasma levels were altered in both groups without any significant differences or clinical consequences. Cumulative nitrogen balance remained negative (-10 g N. day-1 i.e. -100 g N. 10 days-1) and comparable in both groups. However, thyroxin-binding prealbumin concentrations increased significantly in patients receiving the MCT/LCT mixture. It is concluded that MCT might have a beneficial effect on visceral protein metabolism after trauma.

Lung overinflation was observed in a patient ventilated by a Siemens Servo Ventilator 900 C. The expiratory valves failure to open was related to a transducer disconnection in the expiratory limb. This transducer controls opening of the expiratory valve and when disconnected expiratory valve remains closed.
