Anesthésie locorégionale pour la chirurgie esthétique de la face et du cou

Plastic surgery is more and more developing. Facial blocks are adapted to surgical procedures performed in this setting. They are easy to perform and may prolong postoperative analgesia. Facial blocks may be used in ambulatory surgery as a single technique or combined with general anaesthesia or intravenous sedation. After a reminding of facial nerve anatomy, facial and cervical blocks are described with their indications. Guidelines for performance and monitoring are also indicated.     

Efficacité de l’infiltration cicatricielle subfasciale par la bupivacaïne dans la réduction de la douleur postopératoire des hernies inguinales

Introduction

The reduction of postoperative pain after surgery of inguinal hernia is an objective of lot of studies. The subfasciale infiltration of the wound may be an efficient technique.

Methods

This study was designed as a randomized, double blind, prospective study, comparing two treatment groups: a group infiltrated by bupivacaine (Gr B), and second one infiltrated by a placebo (Gr P). A part of demographic parameters and ASA class, the postoperative pain intensity at rest and at coughing, the morphine consumption and the secondary effects were compared. Patient's satisfaction and postoperative chronic pain at 3 and 6 months were also analyzed.

Results

Concerning demographic parameters, ASA class and secondary effects, we didn’t find any meaningful difference between the two groups. However, there was a significant reduction of postoperative pain in the bupivacaine group as well at rest as coughing. Gr P patients have more morphine consumption and they were unsatisfied and accused more chronic pain.

Discussion

Wound infiltration is still a simple and efficient technique in postoperative pain reduction. With this technique, hernia surgery may become ambulatory.     

La chirurgie ambulatoire : organisation pratique et aspects médico-légaux,en France

In France, ambulatory anaesthesia and surgery seem to be well codified. Many recommendations have been published by the Health Authority and the professional associations: they are summarized in this review. However, numerous practical problems persist: for example, two situations specific to paediatric practice are problematic parental comprehension and application of the information provided and poor access to strong analgesics outside the hospital. Despite this, the paediatric population is an ideal target for ambulatory care because of its usual good health and quicker recovery after minor injury as proven by the small percentage of failure and readmission.     

La préhabilitation. Préparer les patients à la chirurgie pour améliorer la récupération fonctionnelle et réduire la morbidité postopératoire

Objective

Prehabilitation consists in providing a repetitive physical exercise before surgery to improve the postoperative recovery course. This review aims to evaluate the feasibility and the expected benefits of prehabilitation on the postoperative recovery course and the reduction of the postoperative morbidity.

Data sources

Data research has focused on English-language articles in the Medline database, published from 1989 to 2013. Keywords, used separately or in combination, were: prehabilitation, functional capacity, postoperative morbidity, physical activity.

Study selection

Selected articles were original articles, clinical cases, review articles and meta-analysis.

Data extraction

Articles were analyzed for feasibility, benefits and limitations of preoperative physical preparation techniques.

Data synthesis

Poor preoperative functional status is associated with increased postoperative morbidity. Elderly are more prone to postoperative complications. The improvement of preoperative physical status of these patients is possible and may reduce morbidity and allow faster recovery after major surgery. In order to improve efficiency, the training program must provide endurance and muscle reinforcement exercises, whose intensity must be adapted to the patient's baseline physical abilities. An average of three sessions per week over a period of six to eight weeks before surgery seemed a good compromise between feasibility and effectiveness.

Conclusion

The effectiveness of prehabilitation has been demonstrated in cardiovascular surgery and probably in abdominal surgery. Prehabilitation must be integrated into the overall patient medical management, and must be associated with preoperative refeeding and postoperative rehabilitation protocols. By optimizing all stages of the surgical patient management, from diagnosis to recovery, prognosis of high-risk surgical patients could be improved.     

Stratégie de réhabilitation postopératoire de la fracture du col fémoral

The femoral neck fracture in elderly patient is an entity that is within the scope of “disease causing a femoral neck fracture”. The specific factors for successful management of these elderly patients are centered around patient's comorbidities, specific management in a clinical pathway, and more or less early rehabilitation after surgery. The type of fracture, surgery, specific treatment, early active recovery for the patients lying in bed after surgery optimize the functional outcome at mean term. The improvement of nutritional status, equilibrium for comorbidities and early rehabilitation with walking activities and physiotherapy significantly improve functional outcome at short and medium terms and postoperative mortality. The use of multimodal analgesia and regional analgesia primarily by perioperative continuous femoral nerve blocks also improve the medical prognosis and functional outcome of the patient.     

Tribloc (fémoral,sciatique, obturateur) pour la chirurgie ambulatoire arthroscopique de genou : étude prospective de faisabilité et d’efficacité

Background

The purpose of this study was to evaluate intra- and postoperative conditions of the triple nerve block technique (femoral, obturator, sciatic block) for outpatient knee arthrsopic procedures.

Methods

After written informed consent, ASA I-III patients received a combined triple nerve block with 30–40 ml lidocaine or mepivacaine (1,5%). Blocks were performed using a nerve stimulation technique. Onset time, block failure, supplemental general anesthesia (GA) or analgesia and pain score were recorded intraoperatively. After surgery, side effects (at days 0, 1, 3, 7 and after 4 weeks), patient and surgeon satisfactions were noted.

Results

Three hundred and twelve patients were screened and 115 triple blocks were performed (157 choosed GA, 19 spinal anaesthesia, 21 exclusion for regional anaesthesia). Failed blocks occurred for 12 (10%) patients. These 12 patients received GA before surgery incision. Time to complete block was 40 (10–60) min. Supplemental GA was required for 12 patients (12%) due to surgical (n = 7, 7%) or tourniquet (n = 5, 5%) pain. Intraoperative surgeon satisfaction was 90 (60–100). After surgery, time to discharge the postoperative care unit was 15 (5–60) min. Pain score at rest (Visual Analog Scale) until six hours was less than 30 /100, without any additionnal morphine. Two patients (< 2%) failed for ambulatory discharge criteria (no relation with triple block). At day 0, 3, 5% patients suffered PONV (8% at D1), paresthesia was noted in 1.7% at D0 (0,8% D3). No other secondary effects were observed after seven days and 91% patients “would like same anaesthesia” for next surgery.

Conclusion

We conclude that triple nerve block provided reliable intraoperative patient and surgical conditions for outpatient knee arthroscopy. Failed block (10%) was the major reason of supplemental anaesthesia. To increase surgical turn over under triple nerve block, a preoperative room may be required (block onset time).     

Effet de la kétamine dans la prévention des douleurs chroniques post-mastectomies. Étude pilote

Objective

This pilot study was designed to evaluate the feasibility of a trial to estimate the preventive effect of ketamine on postmastectomy pain syndrome (PMPS).

Study design

Double-blind, randomized, placebo-controlled pilot trial.

Patients and method

Thirty six patients scheduled for a radical mastectomy with axillary lymph node dissection were randomized in two groups (n = 18 per group). Before skin incision, a bolus (0.5 mg/kg of ketamine or placebo) followed by a continuous infusion (0.25 mg/kg per hour of ketamine or placebo) was administered and discontinued at the end of surgical procedure. We studied the incidence and characteristics of PMPS three months after surgery as well as the feasibility of chosen methods.

Results

Thirty patients were followed for three months (group ketamine n = 12; group placebo n = 18). At three months, there was no significant difference in the incidence of chronic pain, but a tendency to a decrease of hyperalgesia near the scar. There was no repercussion on the quality of life. The characteristics of the PMPS are similar to those described in the recent literature (intercostobrachial neuralgia 33%, neuroma pain 39%, and phantom breast pain 22%). The feasibility of the experimental study is established by the absence of difficulty during the clinical investigation period.

Conclusion

We found no preventive effect of ketamine on the development of PMPS. However, the non-statistically significant effect of ketamine on hyperalgesia three months after surgery could justify a larger study with the same methodology.     

Effet des anesthésiques locaux sur la réponse inflammatoire postopératoire

Current knowledge suggests that peripheral inflammation following surgery activates and sensitizes both peripheral and central nervous system. These phenomena involved in the maintenance of the inflammatory response lead to hypersensibility, hyperalgesia and allodynia. Hyperalgesia participates in the general experience of postoperative pain and ALo in the development of chronic pain. A correlation between the ability of treatments to reduce areas of hypersensitivity surrounding the wound after surgery and their ability to reduce the incidence of chronic pain has been shown. For a long time, local anaesthetics have been used for their capacity to block nociceptive input. They can ALo modulate the inflammatory response following a surgical trauma. By inhibiting the nervous conductivity at the site of the trauma, local anesthetics attenuate the sensitization of the nervous system and therefore the inflammatory phenomena. They ALo exert intrinsic anti-inflammatory properties by modulating the local and systemic liberation of inflammatory mediators. The mechanisms involved are not clearly elucidated. Local, systemic, and spinal inflammatory mechanisms may be influenced by local anesthetics through multiple different mechanisms. The therapeutic implications of effects of local anesthetics on local, systemic, and spinal inflammatory responses merit further study.     

Analgésie postopératoire à domicile : évaluation de la douleur par les parents,information

Postoperative analgesia at home induces necessarily pain assessment by self-report or observational measure. A special scale has been validated for day-case surgery: the PPMP. Nevertheless, children's and parents’ information and education are essential.     

Hypertension pulmonaire et fracture du col fémoral : intérêt de la rachianesthésie continue

Anaesthetic management of patients with pulmonary hypertension is challenging and alternatives to general anaesthesia are encouraged. We report anaesthetic management of two patients with pulmonary hypertension admitted for femoral neck fracture. In order to reduce the risk of right-sided heart failure and systemic hypotension, it was decided to operate the patients under continuous spinal anaesthesia. Anaesthesia was induced with excellent hemodynamic tolerance. Quality and extension of the block was correct and allowed surgery. No postoperative complication was observed. These cases suggest that continuous spinal anaesthesia may be considered for the management of patients with pulmonary hypertension undergoing femoral neck fracture surgery.     

Bradycardie liée à la galantamine

An 80-year-old man had to be operated for cutaneous neoplasia. Local anaesthesia with sedation was required. Preoperative examination revealed a pronounced albeit asymptomatic bradycardia. Electrocardiogram showed a complete atrioventricular block. Use of a pacemaker was discussed. Finally, surgery was performed uneventfully after transient reversal of the anticholinesterasic effects of galantamine administered in Alzheimer's disease control over several hours with atropine.     

Intérêt de l’anesthésie péridurale cervicale dans la gestion périopératoire d’une thyroïdectomie chez une patiente à haut risque anesthésique

Cervical epidural anesthesia is an anesthetic technique that can be useful in patients with high perioperative risk undergoing to cervical surgery. We report the case of a patient of 49 years old with hypertension, diabetes mellitus, epilepsy, left hemiparesis sequelae of stroke and congestive left ventricular failure. The patient underwent total thyroidectomy under cervical epidural anesthesia. No difficulty breathing or decompensation of chronic underlying diseases were noted in the postoperative.     

Hyperthermie maligne : des événements multiples menant à la crise

This case-report focused on the occurrence of a crisis of malignant hyperthermia on a young biker (21 y.o.) victim of a severe traffic accident. This observation gives some key points: the delayed occurrence of the crisis after 4 hours of surgery, the multi-factorial events that triggered the crisis; the choice to perform a quick diagnosis through gene analysis in comparison to the standard tests of caffeine on a muscular biopsy. These different points are discussed with a proposal of algorithm in the situation.     

Rôle de la génétique dans la variabilité interindividuelle en anesthésie

Objective

This review discusses variability among patients in anesthesia, due to genetic polymorphisms.

Data sources

Articles in French and English languages were retrieved from PubMed database. The initial request was “anesth* and (genotyp* or polymorphism* or genetic*)”.

Study selection

Original articles, general reviews and one case report. Letters were excluded.

Data extraction

Rare genetic diseases were excluded from the scope of this review. We stressed on frequent genetic polymorphisms that may have a daily impact in anesthesiology.

Data synthesis

Most results were related to pain studies. We selected various examples to describe how genetic polymorphisms impacts the pharmacology of a given drug, and what are the clinical consequences.

Conclusion

There is a growing field of pharmacogenetic related evidences in anesthesiology. The results from various animal and human studies underline the genetic origin of variability among individuals. How anaesthesists have to integrate these parameters for their daily practice is still unclear, but pharmacogenetic will obviously be a leading field of anesthesia research in the future.     

Évaluation nutritionnelle à la consultation d’anesthésie

The identification of nutritional status is one of the objectives of the anaesthesia consultation often difficult to achieve routinely. It usually requires the use of multiple indicators, which are complex for a non-nutrition specialist. In preoperative period, nutritional assessment should be easy to do in order to identify patients who are malnourished or at risk of malnutrition and relevant information about nutritional risk should be registered in the patient chart. To facilitate this evaluation, we propose a stratification of nutritional risk in four grades (NG) using three types of simple and validated parameters: preoperative nutritional status (BMI, weight loss, eventually serum albumin), comorbidities and kind of surgery. This stratification can develop a tailored nutritional care for each patient.     

Apport de la saturation veineuse centrale en oxygène dans la décision transfusionnelle postopératoire

Objective

The aim of this study was to assess the value of central venous oxygen saturation (ScvO₂) for the decision of blood transfusion in comparison with the criteria of the French guidelines for blood transfusion (2003).

Study design

Prospective, observational.

Patients and methods

Sixty patients, haemodynamically stable, for whom a blood transfusion (BT) was discussed in the postoperative course of general surgery, were included. ScvO₂ (%) and haemoglobin (g/dl) were measured before and after BT. Patients were retrospectively divided into two groups according to ScvO₂ measured before BT (< or ≥ 70%). Results are expressed as median.

Results

The ScvO₂ before transfusion was greater or equal to 70% in 25 (47.2%) patients. Following BT, the ScvO₂ increased significantly (from 57.8 to 68.5%) in the group with initial ScvO₂ less than 70% whereas it was unchanged in patients with initial ScvO₂ greater or equal 70% (from 76.8 to 76.5%). Twenty patients (37.7%) did not meet the French guidelines for BT criteria. Eighteen patients out of 33 that met the criteria had ScvO₂ greater or equal 70% before BT while 13 patients with ScvO₂ less than 70% were not detected by these same criteria.

Conclusion

ScvO₂ could be a relevant biological parameter to complete the current guidelines for BT in stable patient with a central venous catheter during the postoperative period.     

Kystes neurentériques de l’orbite. À propos d’un cas et revue de la littérature

Introduction

Neurenteric cysts defined as a cyst lined by endodermal-type epithelium are extremely rare. We report a rare case of an orbital neurenteric cyst.

Case report

A 19-year-old female presented with an orbital cyst tumor that had cosmetic consequences. The signal of the cyst was not enhanced after administration of gadolinium on MRI examination. The patient underwent surgery due to the increase in size of the tumor. A complete cyst removal including the cyst wall through the inferior palpebral fold was performed. The histological examination confirmed the diagnostic of neurenteric cyst. The patient was discharged home in excellent condition.

Conclusion

This report discusses the clinical presentation, neuroradiological aspect, pathological findings and therapeutic consideration of the neurenteric cyst. We described a rare case of orbital neurenteric cyst. Due to the local recurrence rate observed after partial resection, the goal of the surgery should be a total resection of the cyst with the cyst wall.     

Efficacité d’une manœuvre de recrutement alvéolaire associée à une pression expiratoire positive sur la mécanique respiratoire en cœliochirurgie bariatrique

Objective

To evaluate recruitment manoeuvre (RM) efficiency associated with a 10 cmH₂O positive end expiratory pressure (PEEP) on respiratory mechanic estimated by lung compliance (Ctp) and PEEP to ZEEP expiratory volume delta (Δ VTE) during laparoscopic bariatric surgery in patients with morbid obesity.

Study design

Prospective randomized study.

Methods

Twenty-six obese patients (BMI > 40 kg/m²) undergoing laparoscopic bariatric surgery. The recruitment group received an RM followed by a 10 cmH₂O PEP versus only 10 cmH₂O PEP in the control group. Ctp was measured during the intervention and functional residual capacity (FRC) was estimated measuring Δ VTE during a PEP to ZEP manoeuvre. Mann and Whitney tests as well as a t-test were used (significance p < 0.05).

Results

In the RM group, a significant improvement of 52 ± 14 ml/cmH₂O was noted versus a 36 ± 10 ml/cmH₂O in the PEP group (p = 0,004). This improvement was transitory and no statistically significant Δ VTE difference was noted between the groups at the end of the intervention (360 [90–770] ml [MRA] and 310 [190–450] ml [PEP]).

Conclusion

In patients with morbid obesity undergoing laparoscopic bariatric surgery, an RM conducted prior the pneumoperitoneum temporarily improves lung mechanics but without any change of the end expiratory lung volume at the end of the surgery in comparison with PEP alone. The RM was well tolerated.     

Comparaison prospective et randomisée de la morphine nébulisée versus la péridurale thoracique dans la prise en charge de la douleur des traumatisés thoraciques

Introduction

Successful management of pain reduces morbidity and improves patient satisfaction of patient after a chest trauma. The purpose of the study was to evaluate the efficacy of the respiratory administration of nebulized morphine in such patients.

Patients and methods

Patients were included in this prospective and randomized study patients to receive either nebulized morphine in group M or a mixture of bupivacaine-fentanyl by epidural route. In group M, patients received nebulized morphine every 30 minutes until the second hour then every 4 hours during 48 hours. In the thoracic epidural analgesia group (group P) they received a mixture of 0.125% bupivacaine and 0.115% of fentanyl continuously infused at the rate of 7 ml/h during 48 hours. The main criterion of judgment was the analgesic effects of analgesic regimen with EVA < 4. Sedation, haemodynamic and respiratory parameters were continuously recorded, as adverse side effects were they occurred. Statistical comparisons were performed with Chi², Fisher or Student t-test when appropriate (p < 0.05).

Results

Forty patients were randomized in two groups. Groups were not different regarding the demographic parameters. Analgesia was effective in both groups (NS). Sedation, hemodynamic and respiratory parameters were not different between groups. No side effect was noted in groups.

Conclusion

Nebulized morphine was an analgesic technique as effective as epidural bupivacaine-fentanyl in our series. This non-invasive route of administration of morphine appears to be useful to treat pain after a chest trauma.
