ReviewRescue high frequency oscillatory ventilation versus conventional ventilation for pulmonary dysfunction in preterm infants.
This section is under preparation and will be included in the next issue. ⋯ There is insufficient information on the use of rescue HFOV to make recommendations for practice. The small amount of data that exists suggest that harm might outweigh any benefit. Any future use of HFOV as rescue therapy for preterm infants with severe RDS should be within randomized controlled trials and address important outcomes such as longer term pulmonary and neurological function.

Review Comparative StudyEndometrial resection and ablation versus hysterectomy for heavy menstrual bleeding.
Heavy menstrual bleeding (HMB) or menorrhagia is an important cause of ill health in women. Surgical treatment of HMB often follows failed or ineffective medical therapy and the definitive treatment is hysterectomy but this is a major surgical procedure with significant physical and emotional complications and social and economic costs. A number of less invasive surgical techniques (e.g. endometrial resection and laser ablation) have been developed with the purpose of removing the entire thickness of the endometrium. The benefits claimed for these therapies are reduced trauma and post-operative complications to the woman, reduced need for a general anaesthetic, direct cost savings to the health service due largely to a shift from inpatient to day case treatment and indirect cost savings to society as women return more quickly to their usual activities. However, endometrial hysteroscopic techniques are not always completely successful and additional surgical treatment is required in a proportion of cases. Although initially the resource and patient costs of these techniques are much cheaper than the cost of hysterectomy, the need for re treatment at a later stage may reduce the cost differential. Thus, the effectiveness of these techniques to improve a woman's perception of her own wellbeing long term has yet to be confirmed. ⋯ There was a significant advantage in favour of hysterectomy in the improvement in HMB and satisfaction rates (up to 4 years post surgery) compared with endometrial destruction techniques. Although many quality of life scales reported no differences between surgery groups, there was some evidence of a greater improvement in general health for hysterectomy patients. Duration of surgery, hospital stay and recovery time were all shorter following endometrial destruction. Most adverse events, both major and minor, were significantly more likely after hysterectomy and before discharge from hospital. After discharge from hospital, the only difference that was reported for this group was a higher rate of infection. Repeat surgery because of failure of the initial treatment, either endometrial ablation or hysterectomy, was more likely after endometrial destruction than hysterectomy. (ABSTRACT TRUNCATED)

ReviewEarly versus delayed selective surfactant treatment for neonatal respiratory distress syndrome.
This section is under preparation and will be included in the next issue. ⋯ Early selective surfactant administration given to infants with RDS requiring assisted ventilation leads to a decreased risk of acute pulmonary injury (decreased risk of pneumothorax and pulmonary interstitial emphysema) and a decreased risk of neonatal mortality and chronic lung disease compared to delaying treatment of such infants until they develop established RDS.

ReviewAnti-epileptic drugs for preventing seizures following acute traumatic brain injury.
Seizure activity in the early post-traumatic period following head injury may cause secondary brain damage as a result of increased metabolic demands, raised intracranial pressure and excess neurotransmitter release. ⋯ Prophylactic anti-epileptics are effective in reducing early seizures, but there is no evidence that treatment with prophylactic anti-epileptics reduces the occurrence of late seizures, or has any effect on death and neurological disability. Insufficient evidence is available to establish the net benefit of prophylactic treatment at any time after injury.

ReviewEpidural local anaesthetics versus opioid-based analgesic regimens on postoperative gastrointestinal paralysis, PONV and pain after abdominal surgery.
Gastrointestinal paralysis, nausea and vomiting, and pain, are major clinical problems following abdominal surgery. Anaesthetic and analgesic techniques that reduce pain and postoperative nausea and vomiting (PONV), and prevent or reduce postoperative ileus, may reduce postoperative morbidity, duration of hospitalisation and hospital costs. ⋯ Administration of epidural local anaesthetics to patients undergoing laparotomy reduce gastrointestinal paralysis compared with systemic or epidural opioids, with comparable postoperative pain relief. Addition of opioid to epidural local anaesthetic may provide superior postoperative analgesia compared with epidural local anaesthetics alone. The effect of additional epidural opioid on gastrointestinal function is so far unsettled. Randomized, controlled trials comparing the effect of combinations of epidural local anaesthetic and opioid with epidural local anaesthetic alone on postoperative gastrointestinal function and pain are warranted.
