To identify the growth in the number of anesthetic procedures since 1980 and the changes in the practice of anesthesia, the present survey was designed to collect and analyze the anesthetic activity performed in France in 1996, from a representative sample collected in all French hospitals and clinics.
This study, initiated by the French Society of Anesthesia and Intensive Care, collected information that included the characteristics of patients (age, sex, American Society of Anesthesiologists status), the techniques of anesthesia, and the nature of the procedure for which anesthesia was required. All French private, public, and military hospitals were asked to participate in the survey. In each hospital in the country, all anesthetic procedures were documented and collected during 3 consecutive days, chosen at random during a 12-month period, to obtain a representative sample of the annual activity. All data were analyzed at the INSERM (National Institute of Health and MEDICAL RESEARCH: At the conclusion of the study, 5% of hospitals were randomly assigned to be audited to check for missing data and errors. The rate of anesthetic activity was calculated as the ratio between the annual number of anesthetic procedures and the number of the general population in the same age group.
The participation rate of hospitals was 98%. The analysis of the 62,415 collected questionnaires allowed extrapolation of the anesthetic activity to 7,937,000 anesthetic procedures (95% confidence interval, +/- 387,000) performed in France in 1996. Thus, the annual rate of anesthetic procedures was 13.5 per 100 population, varying between 5.4 per 100 in girls aged 5-14 yr and 30.2 per 100 in men aged 75-84 yr. Surgery was involved in 71% of anesthesia cases. Regional anesthesia alone was performed in 20% of all surgical cases and was combined with general anesthesia in 3% of additional cases. Anesthesia for obstetric procedures represented 9% of all cases. Seventy-six percent of all anesthetic procedures started between 12:00 A.M. and 7:00 A.M. were related to obstetric activities.
In comparison with a previous study, the present survey shows that the number of anesthetic procedures has increased by 120% since 1980, and the rate of anesthetic procedures increased from 6.6 to 13.5 per 100 population, the major changes being observed in patients aged > or = 75 yr and in those with an American Society of Anesthesiologists physical status of 3. In the same time period, the number of regional anesthetic procedures increased 14-fold. In obstetrics, the practice of epidural analgesia extended from 1.5% to 51% of all deliveries of the country.

[Show abstract][Hide abstract] ABSTRACT: Mechanical ventilation can initiate ventilator-associated lung injury and postoperative pulmonary complications. The aim of this study was to evaluate (1) how mechanical ventilation was comprehended by anaesthetists (physician and nurses) and (2) the need for educational programs.

"With the acceleration of the aging population and the development of medical technology, the opportunity of the elderly for surgery has increased significantly in recent years. Most patients have their surgery performed under general anesthesia . Inhalation anesthetics such as isoflurane have been widely used in recent years in clinical and research practices. "
[Show abstract][Hide abstract] ABSTRACT: Postoperative cognitive dysfunction (POCD) is a clinical phenomenon characterized by cognitive deficits in patients after anesthesia and surgery, especially in geriatric surgical patients. Although it has been documented that isoflurane exposure impaired cognitive function in several aged animal models, there are few clinical interventions and treatments available to prevent this disorder. Minocycline has been well established to exert neuroprotective effects in various experimental animal models and neurodegenerative diseases. Therefore, we hypothesized that pretreatment with minocycline attenuates isoflurane-induced cognitive decline in aged rats. In the present study, twenty-month-old rats were administered minocycline or an equal volume of saline by intraperitoneal injection 12 h before exposure to isoflurane. Then the rats were exposed to 1.3% isoflurane for 4 h. Two weeks later, spatial learning and memory of the rats were examined using the Morris Water Maze. We found that pretreatment with minocycline mitigated isoflurane-induced cognitive deficits and suppressed the isoflurane-induced excessive release of IL-1β and caspase-3 in the hippocampal CA1 region at 4 h after isoflurane exposure, as well as the number of TUNEL-positive nuclei. In addition, minocycline treatment also prevented the changes of synaptic ultrastructure in the hippocampal CA1 region induced by isoflurane. In conclusion, pretreatment with minocycline attenuated isoflurane-induced cognitive impairment in aged rats.

"The demand for regional blocks (RBs) from both patients and surgeons has significantly increased in anesthesia practice during the last 30 years (1, 2). Although the studies show a reduction in attendant complications, there are still some serious ramifications of these techniques which can be prevented by adequate training programs (3, 4). "
[Show abstract][Hide abstract] ABSTRACT: The demand for regional blocks from both patients and surgeons has significantly increased in anesthesia practice during the last 30 years. Although the studies show that the complications are rare, regional blocks still have serious difficulties which can be prevented by training programs.
The purpose of this study was to determine the factors affecting the educational methods, attitude and practice of the Turkish anesthesiologists in regional blocks during and following residency programs.
Anesthesiologists were asked to answer a questionnaire. Educational proficiency was determined by at least 50 spinal, 50 epidural and 50 peripheral block applications during residency. Specialists were asked for the numbers of spinal, epidural and peripheral blocks (PBs) they applied in 2009. The mean and median values were calculated.
One hundred and eighty-eight anesthesiologists (84.3 %) agreed to participate in the study. While all participants had made their first attempts in neuraxial blocks (NBs) when they were residents, this ratio was detected as 96.8% for PBs. All participants learned neuraxial and PBs on patients in the operating theater. Education proficiency ratios for spinal, epidural and PBs were 98.1 %, 92.5 % and 62.3 %, respectively. Age, perception of adequate training, nerve block rotation, adequate application in education, following innovations were the factors which significantly affected the number of PBs in practice according to univariate analysis. The participants who consider their applications on NBs were adequate (P = 0.029) and the ones working in state or private hospitals (P = 0.017), applied NBs significantly above the median number.
Anesthesiologists had adequate education and practice of NB applications but a significant proportion of participants (51.8%) lacked both in PBs applications. We believe that NBs are more easily learned than PBs during residency training program.
