Effects of perioperative alcohol cessation interventions on postoperative complications following su

Cochrane Review; three trials (140 participants with risky alcohol intake (3 to 40 units daily) in need of surgery); comparing intensive alcohol interventions aimed at complete alcohol cessation at the time of surgery compared with no intervention. Interventions included educational strategies for alcohol withdrawal and relapse prevention.

Key results

Intensive intervention programmes probably increased the number of participants who quit drinking alcohol and probably reduced postoperative complications. Of 61 participants in the intervention groups, 20 had complications requiring treatment, compared with 33 of 61 participants in the control groups (moderate‐quality evidence). Of 70 participants in the intervention groups, 41 successfully quit drinking, compared to five of 70 participants in the control groups (moderate‐quality evidence). Data were insufficient to show the effect of quitting drinking on the number of deaths (low‐quality evidence), and results show no effect on length of hospital stay. None of the studies reported on the number of participants who continued to avoid risky drinking in the longer term (at three‐, six‐, nine‐, and 12‐month follow‐up).

Included studies were few and reported small sample sizes; therefore one should be careful about drawing firm conclusions based on these results.

\ \ Cochrane Review; seven studies (825 people); comparing five talking therapies for reducing drinking in adult users of illicit drugs (mainly opioids and stimulants).\ Key results\ Talking therapies led to no differences, or only small differences, for the outcomes assessed (abstinence, reduced drinking, and substance use).\ One study found there may be no difference between cognitive‐behavioural coping skills training (CBCST) and the twelve‐step programme.\ Three studies found there may be no difference between brief intervention and usual treatment.\ Three studies found there may be no difference between motivational interviewing (MI) and usual treatment or education only.\ One study found brief motivational intervention (BMI) is probably better at reducing alcohol use than usual treatment (needle exchange), but found no differences in other outcomes.\ One study found intensive MI may be somewhat better than standard MI at reducing severity of alcohol use disorder among women, but not among men and found no differences in other outcomes.\ It is uncertain whether talking therapies reduce alcohol and drug use in people who also have problems with other drugs. High‐quality studies are needed.\ The quality of the evidence was moderate for brief and intensive MI, but low for brief interventions and standard MI, and very low for CBCST versus twelve‐step programme.](https://app.figure1.com/case-detail/093eae3f-817d-490d-af27-5c3f11228acb)

\ \ Cochrane Review; 20 trials (1343 participants); comparing opioid painkillers given before surgery, with the same painkiller given only after surgery.\ Key results\ In one small trial (40 participants) in people undergoing dental surgery, use of pre‐emptive opioids resulted in a small reduction in pain experienced in the first 6 hours after surgery and at 24 to 48 hours (low‐quality evidence). This study did not report on adverse events or 24‐hour morphine consumption.\ For preventive opioids started before the first cut was made and continued over the first day after surgery, pain in the first six hours after surgery was similar to when the first opioid dose was given after the first cut to the skin (10 studies; 706 participants). Postoperative pain 24 to 48 hours after surgery was similar between groups (9 studies; 668 participants; moderate quality evidence). A reduction in 24‐hour morphine consumption was too small to be clinically relevant (11 studies; 526 participants). Not all studies reported on adverse events, but the numbers of participants with respiratory depression, low heart rate, or low blood pressure, were similar between groups (low or very low-quality evidence).\ Overall, we found no convincing evidence that starting opioids before the beginning of surgery reduces levels of pain after surgery or the need for continuing opioids.](https://app.figure1.com/case-detail/0f5d2db2-8a0b-442f-a180-8ac51e985801)

\ \ Cochrane Review; 130 studies with 8341 participants, comparing intravenous ketamine given before, during, or after surgery with an intravenous placebo.\ Bottom line\ Ketamine injected into a vein at the time of operation reduces pain, nausea and vomiting, and use of opioid (morphine‐like) painkillers after operation.\ Key findings\ Compared to people given control treatment, those given intravenous ketamine used less opioid painkiller (by about 1 part in 10), and had less pain (by about 2 parts in 10; moderate‐ or high‐quality evidence). Ketamine may be more effective in operations that are likely to cause more intense pain. People given ketamine requested painkillers 54 minutes later than those who did not receive ketamine (moderate‐quality evidence). Ketamine reduced the risk of postoperative nausea and vomiting by a small amount (high‐quality evidence). Ketamine produced no increased risk of central nervous system side effects (hallucination, nightmares or double vision) (high‐quality evidence).\ Future research should assess ketamine's effect after operations that are accompanied by intense pain such as thoracotomy, back surgery, or amputations. Additionally, assessing ketamine's effects among particular patient groups, for example, the elderly or individuals with a history of substance abuse would be of interest.](https://app.figure1.com/case-detail/329320f2-afd7-46ed-bb58-8e5e956cdffb)

\ \ Which medical treatments are effective for traumatic hyphema, a condition in which blood collects in the eye following trauma, usually a blow to the eye?\ Cochrane Review; 27 studies (2643 participants). Interventions included antifibrinolytic agents taken orally or applied directly to the eye (aminocaproic acid, tranexamic acid, and aminomethylbenzoic acid), oral or topical corticosteroids, other kinds of eyedrops, aspirin, estrogens, traditional Chinese medicine, patching, elevation of the head, and bed rest.\ Main results\ We found no evidence that any medical intervention affected final vision (low certainty evidence). Antifibrinolytic agents did appear to reduce the risk of new bleeding in the eye, but participants taking oral aminocaproic acid (an antifibrinolytic agent) appeared to have more nausea and vomiting compared with participants in the control group. It was unclear whether antifibrinolytics reduced complications of secondary bleeding, because these events were infrequent in the studies. We found no evidence for effectiveness of any other medical intervention in reducing the rate of fresh bleeding or the number of complications, but the evidence for a beneficial effect of any of these interventions was uncertain because the numbers of participants and events were small.](https://app.figure1.com/case-detail/8593bf37-b3cc-4a72-80d7-fa80ec3b6a09)
