The evaluation of services by patients is an essential component of continuous quality improvement in anesthesiology. Little is known, however, about how to achieve this objective. Our goal was to conduct a systematic review of all available studies on patient satisfaction with anesthesia services, thereby ascertaining the present level of knowledge in this field and suggesting ways of improving current measurement methodologies. ⋯ The currently available studies of patient satisfaction are of questionable value. Only rigorous methods and reliable instruments will yield valid and clinically relevant findings of this important issue in anesthesiology.

Meta Analysis
[The laryngeal mask in pediatric adenotonsillectomy. A meta-analysis of medical studies].
Anaesthesia both for adenotomy (AT) and for tonsillectomy (TE) frequently presents a challenge. On one hand, children scheduled for adenotomy often have upper airway infections and are thus at risk of laryngo- and bronchospasm; on the other hand the ENT surgeon and the anaesthetist have to share the "workspace" in the patient's mouth. ⋯ Following several years' use of the mask for this purpose in AT and TE in young children, we report our experience and summarise the literature on this topic. The laryngeal mask represents a safe alternative to intubation, provided there is close cooperation with the ENT surgeon.

Meta Analysis Comparative StudySevoflurane versus propofol for anesthetic induction: a meta-analysis.
We performed this meta-analysis to compare the characteristics of sevoflurane and propofol for the induction of routine anesthesia and for laryngeal mask airway (LMA) insertion. The variables assessed were 1) time to loss of consciousness, 2) incidence of apnea during induction, 3) induction complications, 4) time for successful LMA insertion, 5) success with LMA insertion on first attempt, 6) patient dissatisfaction, and 7) postoperative nausea and vomiting. MEDLINE, Embase, and the Cochrane library databases between January 1992 and October 1999 were reviewed for randomized, controlled trials comparing anesthetic induction between sevoflurane/nitrous oxide and propofol. Data from the 12 randomized, controlled studies were used for the meta-analysis. Sevoflurane induction was associated with a trend toward higher patient dissatisfaction and higher first-time success with LMA. Apnea was less common in the sevoflurane group. The incidence of postoperative nausea and vomiting was significantly more frequent in the sevoflurane group (P < 0.05). This effect was still present when all other variables, except the induction methods, were controlled. The other pooled variables did not show a significant difference between sevoflurane and propofol. Sevoflurane and propofol had similar efficacy for anesthetic induction. However, for routine outpatient surgery, propofol may still be the preferred induction anesthetic because of its favorable induction of anesthesia characteristics, high patient satisfaction, and less frequent incidence of postoperative nausea and vomiting. ⋯ Sevoflurane and propofol had similar efficacy for anesthetic induction.

Meta Analysis
General versus regional anaesthesia for hip fracture surgery: a meta-analysis of randomized trials.
Hip fracture surgery is common and the population at risk is generally elderly. There is no consensus of opinion regarding the safest form of anaesthesia for these patients. We performed a meta-analysis of 15 randomized trials that compare morbidity and mortality associated with general or regional anaesthesia for hip fracture patients. ⋯ No other outcome measures reached a statistically significant difference. There was a tendency towards a lower incidence of myocardial infarction, confusion and postoperative hypoxia in the regional anaesthetic group, and cerebrovascular accident and intra-operative hypotension in the general anaesthetic group. We conclude that there are marginal advantages for regional anaesthesia compared to general anaesthesia for hip fracture patients in terms of early mortality and risk of deep vein thrombosis.

Meta AnalysisEffects of general and locoregional anesthesia on reproductive outcome for in vitro fertilization: a meta-analysis.
The objective of this meta-analysis was to evaluate prospective trials of general or locoregional anesthesia on reproductive outcomes (cleavage and pregnancy rate) for in vitro fertilization (IVF). Of 115 published studies retrieved from a search of articles indexed on MEDLINE from 1966 to February 1999, four studies with distinct general and locoregional anesthesia were deemed eligible for meta- analysis. The pooled relative risk and odds ratios were calculated. ⋯ Heterogeneity was negative. Cleavage and pregnancy rates were not significantly different in both the general anesthesia and locoregional anesthesia groups. Both anesthetic techniques were favorable to IVF procedure by available published evidence when anesthesia was needed.
