Abstract
The face-grafting techniques are innovative and highly complex, requiring well-defined organization of all the teams involved. Subsequent to the first report in France in 2005, there have been 17 facial allograft transplantations performed worldwide. We describe anaesthesia and postoperative management, and the problems encountered, during the course of seven facial composite tissue grafts performed between 2007 and 2011 in our hospital. The reasons for transplantation were ballistic trauma in four patients, extensive neurofibromatosis in two patients, and severe burns in one patient. Anaesthesia for this long procedure involves advanced planning for airway management, vascular access, technique of anaesthesia, and fluid management. Preparation and grafting phases were highly haemorrhagic (>one blood volume), requiring massive transfusion. Median (range) volumes given for packed red cell (PRC) and fresh-frozen plasma (FFP) were 64.2 ml kg(-1) (35.5-227.5) and 46.2 ml kg(-1) (6.3-173.7), respectively. Blood loss quantification was difficult because of diffuse bleeding to the drapes. The management of patients with neurofibromatosis or burns involving the whole face was more difficult and haemorrhagic than the patients with lower face transplantation. Average surgical duration was 19.1 h (15-28 h). Postoperative severe graft oedema was present in most patients. Most patients encountered complications in ICU, such as renal insufficiency, acute respiratory distress syndrome, and jugular thrombosis. Opportunistic bacterial infections were a feature during the postoperative period in these highly immunosuppressed patients.

Abstract
OBJECTIVE The European Society for Clinical Nutrition and Metabolism (EPSEN) guidelines on nutrition for liver disease patients has been recently updated. The aim of our study was to evaluate perioperative nutrition in cirrhotic patients waiting for liver transplantation (LT). STUDY DESIGN Prospective electronic survey. A standardized questionnaire was sent to the anaesthesiologist of the 18 French adult LT centers. The questionnaire had closed-ended questions to evaluate nutritional practices in cirrhotic patients waiting for a LT. RESULTS The response rate was 100%. Nutritional status of the cirrhotic patients waiting for LT was assessed by anaesthesiologists (12 centres) and/or hepatologists (11 centres) and more rarely by nutrition physician, dietetics or liver surgeons. Body mass index (13 centres), weight loss (10 centres), albuminemia (10 centres) were the most frequent items used to assess the nutritional status. Before LT, preoperative oral intakes were administered in undernourished patients in only 55% of the cases. Postoperatively, nutritional support was administered between day 1 and 3 after LT. CONCLUSION Perioperative nutritional practices in cirrhotic patients waiting for LT are heterogeneous between centers, especially about nutrition assessment. Most of the centres did not follow the actual guidelines.

Abstract
A growing number of old or very old patients benefits from a surgical procedure. Age is an independent risk factor of postoperative mortality and postoperative complications including cognitive dysfunction. The choice of anesthetic technique does not significantly modify this risk. Preventive strategies and preoperative procedures can be implemented. A multidisciplinary management involving all care providers around the patient is essential to reduce the risk of dependence after surgery which is higher in this population. Early postoperative rehabilitation is recommended in the elderly to improve the prognosis.

Abstract
PURPOSE We report a case that involved immediate postoperative respiratory failure necessitating tracheal intubation, which was possibly related to recurarization after sugammadex reversal. CLINICAL FINDINGS A 54-yr-old woman weighing 115-kg was scheduled for laparoscopic repair of abdominal dehiscence under general anesthesia. Muscle relaxation was induced and maintained with rocuronium (170 mg iv total dose). At the end of the 170-min procedure, two twitches were visualized after supramaximal train-of-four (TOF) stimulation at the adductor pollicis muscle, and the patient's central core temperature was 35.6°C. Sugammadex 200 mg iv (1.74 mg·kg(-1)) was administered. With the patient fully awake, a TOF ratio 0.9 was obtained five minutes later. The tracheal tube was then removed, and the patient was transferred to the postanesthesia care unit. Ten minutes later, the patient presented respiratory failure necessitating tracheal intubation and sedation with propofol. One TOF response only was visualized at the adductor pollicis muscle. Another dose of sugammadex 200 mg iv was administered. Forty-five minutes later, the patient was fully awake and her trachea was extubated after repeated measures of the TOF ratio (≥ 0.9) at the adductor pollicis muscle. The patient fully recovered without sequelae, further complication, or prolonged hospital stay. CONCLUSION Shortly after tracheal extubation, an obese patient experienced respiratory failure necessitating tracheal intubation and an additional dose of sugammadex. This occurred despite initial reversal of neuromuscular blockade with an appropriate dose of sugammadex 2 mg·kg(-1) iv given at two responses to TOF stimulation.

Abstract
BACKGROUND Etomidate and ketamine are used during induction of anesthesia in high-risk patients. However, their effects on action potential (AP) variables and ischemia/reperfusion-induced arrhythmias and conduction blocks are unknown. METHODS Guinea pig right ventricular muscle strips were mounted in a 5-mL double chamber bath with the strips separated into two zones by an impermeable latex membrane. One-half (normal zone) was exposed to normal perfusate while the other half (altered zone) was exposed to hypoxia, hyperkalemia, acidosis, and lack of glucose. AP variables were recorded continuously in the normal and altered zones. Spontaneous arrhythmias and conduction blocks were noted. Etomidate (10(-7), 10(-6), and 10(-5) M) and ketamine (10(-6), 10(-5), and 10(-4) M) were superfused into the bath throughout the experiment and the electrophysiologic effects compared with the control group. RESULTS We found that under control conditions, etomidate and ketamine did not modify resting membrane potential, maximal upstroke velocity, AP amplitude, or AP duration at 90% of repolarization (APD90). Ketamine (10(-4) M), but not weaker concentrations and none of the concentration of etomidate, reversed the ischemia-induced shortening of APD90 and APD dispersion. Etomidate and ketamine did not modify the occurrence of conduction block during simulated ischemia. In contrast, ketamine (25% at 10(-6) M, 13% at 10(-5) M, and 13% at 10(-4) M vs 90% in the control group, P < 0.05) but not etomidate (38% at 10(-7) M, 63% at 10(-6) M, and 63% at 10(-5) M vs 90% in the control group, NS) decreased the incidence of reperfusion-induced spontaneous arrhythmias. CONCLUSIONS In guinea pig myocardium, our data suggest that ketamine, in clinically relevant concentrations, decreases ischemia-induced AP shortening and spontaneous reperfusion-induced ventricular arrhythmias. Further study is required to precisely determine the effect of etomidate on reperfusion-induced arrhythmias.

Abstract
Spinal anaesthesia is the gold standard for elective caesarean section. This technique presents several adverse effects. We report a severe case of hypothermia (33.3 degrees C) after spinal administration of bupivacaine (10 mg) and morphine (100 microg) for elective caesarean section. After excluding other causes of hypothermia, this one could be explained by both the own effects of local anaesthesia (i.e. peripheral vasodilatation) and by the central effect of intrathecal morphine. Because hypothermia is not predictable after spinal injection of morphine both monitoring of central temperature and active warming of the patients could be proposed. Naloxone has been proposed in a case of hypothermia related to spinal injection of morphine.

Abstract
OBJECTIVE To determine the protective action of hyaluronidase on peribulbar anesthesia-related diplopia in patients undergoing cataract surgery. DESIGN Single-center observational case series. PARTICIPANTS All patients undergoing elective phacoemulsification and intraocular lens implantation under peribulbar anesthesia between February 2001 and January 2003. METHODS We compared the incidence of postoperative diplopia between 2 periods--February 2001 to January 2002 (P1) and February 2002 to January 2003 (P2)--which differed by the presence (P1) or absence (P2) of hyaluronidase in the anesthetic solution. MAIN OUTCOME MEASURES All patients were examined on the first and fifth postoperative days during both periods. When diplopia was diagnosed, we recorded the characteristics of the patient, peribulbar anesthesia, and diplopia (orthoptic examination, and magnetic resonance imaging in some cases). RESULTS Seven thousand two hundred five patients were studied. During P1, 3582 patients received peribulbar anesthesia, and no cases of diplopia occurred. During P2, 3623 patients received peribulbar anesthesia, and 27 cases of diplopia occurred (incidence, 0.75%; P = 0.0002 vs. P1). Diplopia involved the inferior rectus (40%) and the external rectus (37%) muscles. Diplopia was persistent in 54% of the cases. CONCLUSIONS Peribulbar anesthesia-related diplopia was significantly more frequent when hyaluronidase was not added to the anesthetic solution.

Abstract
BACKGROUND Measure of blood flow velocity in retrobulbar vessels is performed to determine the severity of ophthalmic pathologies as glaucoma. In children, this measure is usually performed under general anaesthesia. Sevoflurane is known to not modify cerebral blow flow velocities. However, its effect on retrobulbar circulation is not known. This study was designed to evaluate the effect of sevoflurane on retrobulbar circulation flow velocity in children undergoing examination for ocular disorders under general anaesthesia. METHODS Thirteen mechanically ventilated children (Fi(O2))=1) were included. Blood flow velocities of central retinal artery, ophthalmic artery, and middle cerebral artery were measured by Doppler ultrasound during 1 and 2 age-adjusted minimal alveolar concentration (MAC) sevoflurane anaesthesia. Intra-ocular pressure and non-invasive haemodynamic parameters were also measured. End-tidal carbon dioxide tension was controlled during all the study period. RESULTS Mean arterial pressure decreased from 1 to 2 age-adjusted MAC sevoflurane (58 [12] vs 54 [12] mm Hg, P=0.01). In the ophthalmic artery, end diastolic velocity (EDV) decreased significantly at 2 MAC (1 MAC: 4.4 [4] cm s(-1) vs 2 MAC: 1.4 [2.4] cm s(-1); P=0.04) and resistivity index (RI) increased significantly (1 MAC: 0.83 [0.11] vs 2 MAC: 0.93 [0.09]; P=0.007). Systolic velocity, EDV, and RI remained constant in the central retinal artery and in the middle cerebral artery. CONCLUSION High alveolar concentration of sevoflurane decreased blood flow velocity in the ophthalmic artery, but not in the central retinal and the middle cerebral arteries in children ventilated in hyperoxic condition. This effect was related to a decrease in mean arterial pressure. This vessel-dependent effect may be explained by the different autoregulatory mechanisms of these arteries. In the present hyperoxic conditions, the vascular effect of sevoflurane may have been limited in the central retinal artery and not in the ophthalmic artery.

Abstract
BACKGROUND Tracheal mucosal damage related to tracheal intubation has been widely described in pediatric and adult patients. High volume-low pressure cuffs (HVLPC) are being advertised as safe to avoid this particularly unpleasant complication. Compliances of these supposed pediatric and adult HVLPC are not mentioned by manufacturers and still remain unknown. METHODS The compliance of HVLPC was measured in vitro and defined as the straight portion of the pressure-volume curve. Cuff pressure was measured after incremental 0.1 ml filling volumes of air for sizes 3.0-8.0 of internal diameter of Rüsch and Mallinckrodt tracheal tubes. Compliances were assessed in air and in a rigid tube. The filling volume to achieve a 25-mmHg intracuff pressure was also measured. RESULTS In air, each 0.1 ml step almost linearly increased cuff pressure by 1 mmHg (size 8.0) to 9 mmHg (size 3). In air, the volume needed to maintain a cuff pressure < 25 mmHg was small for sizes 3-5.5 (0.35-2 ml). The 25 mmHg inflated cuff volume and compliance were decreased within a rigid tube, especially for adult sizes. In a rigid tube simulating a trachea, the compliances of almost every Rüsch tracheal tube were statistically higher than those of the Mallinckrodt. CONCLUSION We conclude that the tested tracheal tube cuffs have low compliance and cannot be defined as high volume-low pressure.

Abstract
We report the cases of five patients who have experienced postoperative diplopia after cataract surgery under peribulbar anaesthesia and in whom orbital Magnetic Resonance Imaging was performed immediately after the diagnosis. In four patients, the imaging study showed a T2 hyper-intensity signal and swelling of one extraocular muscle that was interpreted as oedema. Therefore, these cases were most probably a result of an accidental i.m. injection of local anaesthetics. In the other patient, the imaging study revealed no abnormality.

Abstract
BACKGROUND Residual neuromuscular blockade remains a problem even after short surgical procedures. The train-of-four (TOF) ratio at the adductor pollicis required to avoid residual paralysis is now considered to be at least 0.9. The incidence of residual paralysis using this new threshold is not known, especially after a single intubating dose of intermediate-duration nondepolarizing relaxant. Therefore, the aim of the study was to determine the incidence of residual paralysis in the postanesthesia care unit after a single intubating dose of twice the ED(95) of a nondepolarizing muscle relaxant with an intermediate duration of action. METHODS Five hundred twenty-six patients were enrolled. They received a single dose of vecuronium, rocuronium, or atracurium to facilitate tracheal intubation and received no more relaxant thereafter. Neuromuscular blockade was not reversed at the end of the procedure. On arrival in the postanesthesia care unit, the TOF ratio was measured at the adductor pollicis, using acceleromyography. Head lift, tongue depressor test, and manual assessment of TOF and DBS fade were also performed. The time delay between the injection of muscle relaxant and quantitative measurement of neuromuscular blockade was calculated from computerized anesthetic records. RESULTS The TOF ratios less than 0.7 and 0.9 were observed in 16% and 45% of the patients, respectively. Two hundred thirty-nine patients were tested 2 h or more after the administration of the muscle relaxant. Ten percent of these patients had a TOF ratio less than 0.7, and 37% had a TOF ratio less than 0.9. Clinical tests (head lift and tongue depressor) and manual assessment of fade showed a poor sensitivity (11-14%) to detect residual blockade (TOF < 0.9). CONCLUSION After a single dose of intermediate-duration muscle relaxant and no reversal, residual paralysis is common, even more than 2 h after the administration of muscle relaxant. Quantitative measurement of neuromuscular transmission is the only recommended method to diagnose residual block.

PURPOSE To compare, over a 48-hr follow-up period, the analgesia and side-effects of patient controlled iv analgesia (PCA) with morphine alone vs combined intrathecal and PCA morphine (IT+PCA) in patients undergoing major abdominal surgery. METHODS Sixty adult patients undergoing abdominal surgery for cancer were randomly allocated to receive preoperative IT (0.3 or 0.4 mg) plus postoperative PCA morphine or postoperative PCA morphine alone. Postoperative analgesia was tested at rest and while coughing on a visual analogue pain scale and morphine consumption was recorded. Patients' satisfaction, arterial oxygen saturation, respiratory rate, episodes of nausea, vomiting and pruritus were also noted. RESULTS Analgesia at rest and while coughing was significantly better in the IT+PCA morphine group (rest: P = 0.01; coughing: P = 0.005) on the first postoperative day only. IT+PCA morphine constantly provided adequate analgesia during this period. Morphine consumption was lower in the IT+PCA morphine group during this period also (IT+PCA: 9 (17) vs PCA: 40 (26); mg of morphine, mean (SD), P = 0.0001). No difference was found in pain relief and morphine consumption between the groups on the second postoperative day. Nausea and vomiting were more frequent with IT+PCA morphine on the first postoperative day. No respiratory depression occurred in either group. Satisfaction was high in both groups. CONCLUSIONS IT+PCA morphine improves patient comfort constantly during the first postoperative day after major abdominal surgery. However, after the first postoperative day, IT+PCA morphine provides no additional benefit.

Abstract
A 67-year-old patient suffering from an ocular myasthenia gravis was scheduled for an elective ENT surgery. General anaesthesia was induced intravenously. Neuromuscular responses after train-of-four stimulation were normal at both the adductor pollicis (T(4)/T(1) = 1) and the corrugator supercilii (4 visual responses). Then cisatracurium (0,15 mg kg(-1)) was administered to allow tracheal intubation. The laryngoscopy attempted 45 s after cisatracurium injection (no response at the supercilii, T(1)/T(0) = 1 at the adductor pollicis) was unsuccessful because of closing and moving vocal cords. The second attempt was successful 4 min after cisatracurium injection (no response at the corrugator supercilii, T(1)/T(0) = 0.05 at the adductor pollicis). Residual neuromuscular blockade was antagonized at the end of surgery (1 h long) allowing an uneventful extubation. We concluded that monitoring neuromuscular blockade at the corrugator supercilii to assess the intubating conditions is not recommended in a case of ocular myasthenia gravis.
