ABSTRACT
BACKGROUND: The anesthesiologist's involvement in perioperative medicine has significantly changed. In order to identify patients at risks of perioperative complications, the anesthesiologist has to consider, amongst others, screening and management of undernutrition. For this purpose knowledge of prevalence and risk factors, along with screening tools and guidelines for an adapted nutritional management and outcomes of renutrition are mandatory. The present review intends to provide these tools to the Anesthesiologists. METHOD: We conduct a literature review in Pubmed, Direct Science and Cochrane Library without limit of time related to undernutrition in the perioperative period. RESULTS: Undernutrition is common in surgical patients. Undernutrition is associated with an increase of morbidity, mortality, length of hospital stay and costs. Undernutrition could probably be detected during the anesthetic consultation with simple and rapid tests, such as SNAQ, MST, MUST and NRS-2002. Nevertheless, further studies are needed to validate such tests in surgical patients. Waiting for these results, we prefer MUST. The implementation of nutritional support recommendations would reduce postoperative complications. CONCLUSION: The anesthesiologist could play an important role in undernutrition screening and its management in order to reduce perioperative morbidity.

Rigid bronchoscopy under general anesthesia enables performing diagnostic and/or therapeutic procedures in the tracheobronchial tree. This technique is characterized by specific technical problems, insofar as the anesthesiologist and the operators share the same space, namely the airway. Several potential complications (hemorrhage inside the airway, threat to ventilation ...) may arise. These challenges render the ability to use the variable available techniques essential, as well as knowledge of the complications they could entail, and the ability to rapidly solve them. General anesthesia is usually total intravenous anesthesia, using short acting agents. Ventilation can be spontaneous, but more often insured using high-frequency jet ventilation. The hospital infrastructure and staff must have the expertise to perform this particular procedure, in order to limit the complication rate.

OBJECTIVE: In order to reduce the risk of postoperative apnoea, awake spinal anaesthesia or awake caudal anaesthesia are recommended for hernia surgery in newborn babies and former premature infants aged less than 60 weeks of amenorrhoea. However, additional sedation is sometimes necessary. Our working hypothesis was that a general anaesthesia with a face mask (sevoflurane) with no opiates nor neuromuscular blocking agents, maintaining the infant's spontaneous breathing and combined with a caudal anaesthesia, could provide a safe and effective alternative. STUDY DESIGN: The epidemiological and technical data about the patient and the anaesthesia, as well as any per- and postoperative complications, were collected prospectively and analysed retrospectively. PATIENTS AND METHODS: Ninety-eight infants undergoing hernia surgery were included during the period from 2003 to 2008. RESULTS: Caudal anaesthesia proved successful at first attempt in 69% of the infants (term or premature). Three attempts were needed in 8% of the infants born at term and 2% of the infants born prematurely. One failure was recorded. Seven patients presented one episode of peroperative apnoea; they were easily taken care of by means of brief face mask ventilation. The follow-up of these seven infants did not reveal any reappearance of postoperative apnoea/bradypnoea. CONCLUSION: The technique proposed is an effective alternative to the awake locoregional anaesthesia techniques: it provides excellent conditions for surgery and presents similar perioperative morbidity and risk of postoperative apnoea.
