[Ambulatory Essure implant placement sterilization procedure for women: prospective study comparing general anesthesia versus hypnosis combined with sedation]. / Étude prospective comparant l'hypnosédation et l'anesthésie générale pour la pose de dispositif de stérilisation intratubaire en ambulatoire.

OBJECTIVE: implant placement Essure, sterilization procedure for women, were performed under hypnosedation (HYP) and compared to the operative anxiety and analgesia of 12 patients operated-on under general anesthesia (GA). STUDY DESIGN: prospective and comparative group study. PATIENTS AND METHODS: two groups of twelve patients were matched and compared based on the choice of anesthetic technique: hypnotics (HYP) with possible additional sedation by propofol and remifentanil or GA involving propofol, sevoflurane and remifentanil. The assessment of anxiety and pain based on a visual analogy scale (0-10) and use of analgesics were studied in the recovery room and at discharge of hospital. The statistical analysis relies on nonparametric tests for paired data (Wilcoxon test). RESULTS: all patients were operated. The two groups are statistically comparable. The preoperative anxiety before premedication is lower in the HYP group (p<0.05). No conversion to general anaesthesia is necessary in the HYP group, but five patients were using sedatives drugs but doses are very low compared to general anaesthesia. The analgesic consumption was equivalent in both groups. CONCLUSION: we conclude that hypnosedation is a valuable alternative to traditional anesthetic techniques for ambulatory Essure implant. The use of hypnotic tool is an interesting alternative for the management of patients during invasive medical procedures or surgical, providing psychological benefits to the patient.

Modulation of airway remodeling-associated mediators by the antifibrotic compound, pirfenidone, and the matrix metalloproteinase inhibitor, batimastat, during acute lung injury in mice.

Matrix metalloproteinases (MMPs) are potent to degrade basement membrane collagen associated with acute lung injury in inflammatory processes. We have investigated effects of pirfenidone, antifibrotic agent, and batimastat, inhibitor of MMPs, on gelatinase activities, on release of tumor necrosis factor-alpha (TNF-alpha) and transforming growth factor-beta (TGF-beta), as well as on recruitment of inflammatory cells in bronchoalveolar lavage (BAL) fluid after aerosol administration of lipopolysaccharide (LPS) in mice. Pretreatment with pirfenidone reduced neutrophil recruitment, TNF-alpha and TGF-beta levels, and MMP-9 secretion. In contrast, pretreatment with batimastat (30 or 60 mg/kg, i.p.) only reduced TNF-alpha and TGF-beta levels. Batimastat did not reduce MMP secretion in BAL fluid but inhibited MMP-9 activity. The increase in tissue inhibitor of matrix metalloproteinase (TIMP)-1 induced by LPS was not modified by the two drugs. These findings demonstrate that the two drugs can inhibit the in vivo increase in MMP induced by LPS, batimastat with a direct inhibitor effect on MMP activity and pirfenidone as a consequence of its antiinflammatory effect.
