SummaryPsychotropic analgesic nitrous oxide for alcoholic withdrawal statesAlcoholism is a global problem with approximately 5-10% of the world's population demonstrating alcohol-related diseases. One of the most severe consequences of alcohol dependence is the withdrawal syndrome. This review assessed the effects of psychotropic analgesic nitrous oxide (PAN) in treating alcohol withdrawal. All trials were conducted in in-patient settings although PAN is also administered in outpatient settings. The review found that PAN is as effective as sedatives for managing mild to moderate alcohol withdrawal states. Nonetheless, it does not provide strong evidence in favour of the benefits or harms of using PAN over sedatives in managing acute alcohol withdrawal. Further high quality trials should be done before these findings can be confirmed.

April 18. 2007 AbstractBackgroundAlcoholism is a global problem with 5-10% of the world's population demonstrating alcohol-related diseases. One of the most severe consequences of alcohol dependence is the withdrawal syndrome, for which benzodiazepines are the most popular current treatment. An alternative method to benzodiazepine employs psychotropic analgesic nitrous oxide (PAN). ObjectivesTo assess the effects of PAN for treating alcohol withdrawal states Search strategyWe searched the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 2, 2005), MEDLINE, EMBASE, CINAHL (all to May 2005). We scanned Internet web sites, reference lists of relevant articles and abstracts of the international Conferences on Alcoholism. We contacted researchers in the field and industry to identify unpublished trials. No language and publication restrictions. Selection criteriaRandomised controlled trials including voluntary participants dependent on alcohol. PAN was compared to oxygen and/or benzodiazepine regimens. Data collection and analysisTwo authors independently assessed the methodological quality of the trials and extracted data. Main resultsFive studies, 212 participants, were included. PAN showed improvement of symptoms (RR 1.35; 95% CI 1.01 to 1.79), of the amount and duration of sedative medication and of psychomotor function (WMD -8.71; 95% CI -13.71 to -3.71). At one hour post intervention, no significant differences were found for depression (WMD -2.40; 95% CI -8.70 to 3.89) and anxiety (WMD -3.70; 95% CI -10.53 to 3.12). None of the included studies reported any significant adverse effects of any treatment. Authors' conclusionsResults indicate that PAN may be an effective treatment of the mild to moderate alcoholic withdrawal state. The rapidity of the therapeutic effect of PAN therapy coupled with the minimal sedative requirements, may enable patients to enter the psychological treatment phase more quickly than those on sedative regimens, accelerating the patients recovery. Our review does not provide strong evidence due to the small sample sizes of the included trials. Neither does the review indicate any causes for concern that PAN is more harmful than the benzodiazepines. Clinicians wishing to use PAN may initially wish to do so within trial settings. |
