Can hypothermia be evidenced during laparoscopic cholecystectomy?

Maintenance of pneumoperitoneum to perform laparoscopic surgery with carbon dioxide (CO2) could induce hypothermia. The authors assessed the mean body temperature (MBT) and changes in total body heat content (TBHC) under laparoscopic cholecystectomy. Thirty-six ASA I-II female patients underwent open cholecystectomy (Group-O, n = 18) or laparoscopic cholecystectomy (Group-L, n = 18). Esophageal temperature and four skin-surface temperatures were measured before induction and then every 10 minutes, and at arrival to the postanesthesia care unit. Operating room temperature was 22.9 +/- 1.2 degrees C. Operating time was as follows: G-O, 74 +/- 21 minutes; G-L, 94 +/- 16 minutes. After 60 minutes of surgery, decrease in TBHC was as follows: G-L = 54.9 kJ and G-O = 40.9 kJ. Decrease in MBT after 60 minutes intervention and at arrival to the postanesthesia care unit was as follows: G-L = 0.13 and 0.66 degree C and G-O = 0.17 and 0.49 degree C, respectively. There were no statistically significant differences between groups. Minor differences were attributed to longer surgery duration in the laparoscopic group.

Localized pustulosis induced by betalactams.

Localized forms of pustular drug eruptions related to antibiotics are uncommon and their mechanism is still unknown. We describe herein a patient who developed numerous pin-head pustules without erythema in the peribuccal area after ingestion of ceftibuten and amoxicillin. The relationship with these drugs was confirmed by single-blind oral challenges. The following tests were performed: prick and intradermal tests with benzylpenicilloyl polylysine, minor determinant mixture, benzylpenicillin and amoxicillin; patch tests were also carried out with benzylpenicillin, amoxicillin, cloxacillin, cefuroxime, ceftriaxone, cefazolin, ceftibuten and cefaclor. All cutaneous tests were negative. Controlled single-blind challenge tests were performed with amoxicillin, cefadroxil, ceftibuten, cefuroxime, cefaclor, erythromycin and ciprofloxacin. All betalactam antibiotics tested gave a positive reaction, with good tolerance of other antibiotics; this would appear to indicate a specific mechanism of hypersensitivity and not an unspecific reaction to wide spectrum antibiotics.

[Evaluation and evolution of the scientific production by Spanish anesthesiology departments].

OBJECTIVES: To count the scientific publications coming from Spanish departments of anesthesiology and rank them by productivity using various bibliometric tools. To examine the evolution of productivity between 1992 and 2001. METHOD: Abstracts of articles from Spanish anesthesiology departments were located on Medline. Hospital departments were ranked by productivity based on number of publications. Other classifications were established based on the international impact of articles measured by "net" impact factor (IF) of the journals and "relative" IF (according to the category assigned by Journal Citation Reports [JCR]). The evolution of scientific productivity was analyzed by five-years periods. RESULTS: We located 644 entries for articles published in Spanish journals and 182 for articles in journals outside Spain. Ten departments of anesthesiology produced 68% of the articles in non-Spanish journals. Hospital Clinic i Provincial in Barcelona was the most productive (55 publications, 27 in foreign journals). Hospital del Mar published articles in journals with the highest IF (mean 2.63). When IF results were adjusted by JCR category, Hospital Clinic i Provincial had the best quantitative and qualitative indexes. Hospital Torrecardenas had the best evolution in scientific productivity in the last five years. CONCLUSION: The scientific productivity of Spanish anesthesiology departments has evolved favorably over the past 10 years, led by Hospital Clinic i Provincial.

[Techniques for identifying the epidural space].

A large part of the success of epidural anesthesia rests on correct identification of the epidural space. The last hundred years have seen the description of numerous techniques for locating the space in the most straightforward, effective, safe, and reliable manner. To evaluate the advantages and disadvantages of these approaches and the complications associated with each, we carried out a MEDLINE search using the following key words: "epidural analgesia," "epidural anesthesia," "epidural space," "identification," and "loss of resistance" (LOR). Traditional, complementary, and instrument-guided techniques used to identify the epidural space were analyzed. The results of clinical trials comparing different LOR techniques were evaluated. LOR with air, with isotonic saline, or a combination of both were the techniques shown to be simplest and safest. With respect to safety, LOR with air led to the greatest number of complications (pneumocephalus, air embolism, insufficient analgesia, higher incidence of dural puncture, nerve root compression, subcutaneous emphysema). When a small air bubble is created inside the syringe, LOR with saline solution is reliable and teachable, as well as safe and effective.
