Review Meta AnalysisBenzodiazepines alone or in combination with antipsychotic drugs for acute psychosis.
Acute psychotic illness, especially when associated with agitated or violent behaviour, can require urgent pharmacological tranquillisation or sedation. In several countries, clinicians often use benzodiazepines (either alone or in combination with antipsychotics) for this outcome. ⋯ There is insufficient data from these studies to support or refute the use of benzodiazepines with or without antipsychotics where emergency drugs are needed. The sole use of older antipsychotics unaccompanied by anticholinergic drugs may be problematic, but studies in this review are not large enough to identify any serious adverse effects of benzodiazepines such as respiratory depression. Larger, more informative studies are needed before definite conclusions can be drawn as to the efficacy of benzodiazapines.

Review Meta AnalysisUrinary catheter policies for short-term bladder drainage in adults.
Indwelling urinary catheters are often used for bladder drainage during hospital care. Urinary tract infection is a common complication. Other issues that should be considered when choosing an approach to catheterisation are patients' comfort, other complications/adverse effects, and costs. ⋯ There was evidence that suprapubic catheters have advantages over indwelling catheters in respect of bacteriuria, recatheterisation and discomfort. The clinical significance of bacteriuria was uncertain, however, and there was no information about possible complications or adverse effects during catheter insertion. There was more limited evidence that the use of intermittent catheterisation was also associated with a lower risk of bacteriuria than indwelling urethral catheterisation, but might be more costly. Using intermittent catheterisation postoperatively limits catheterisation to those people who definitely need it.

Review Meta AnalysisAntibiotic prophylaxis for bacterial infections in afebrile neutropenic patients following chemotherapy.
Bacterial infections are a major cause of morbidity and mortality in neutropenic patients following chemotherapy for malignancy. Trials have shown the efficacy of antibiotic prophylaxis in decreasing the incidence of bacterial infections, but not in reducing mortality rates. ⋯ Our review demonstrated that prophylaxis significantly reduced all-cause mortality. The most significant reduction in mortality was observed in trials assessing prophylaxis with quinolones. The benefit demonstrated in our review outweighs harm, such as adverse effects, and development of resistance, since all-cause mortality is reduced. Since most trials in our review were of patients with haematologic cancer, prophylaxis, preferably with a quinolone, should be considered for these patients.

Review Meta AnalysisTransient neurologic symptoms (TNS) following spinal anaesthesia with lidocaine versus other local anaesthetics.
Spinal anaesthesia has been in use since the turn of the late nineteenth century. During the last decade there has been an increase in the number of reports implicating lidocaine as a possible cause of temporary and permanent neurologic complications after spinal anaesthesia. Follow-up of patients who received uncomplicated spinal anaesthesia revealed that some of them developed pain in the lower extremities after an initial full recovery. This painful condition that occurs in the immediate postoperative period was named "transient neurologic symptoms" (TNS). ⋯ The risk of developing TNS after spinal anaesthesia with lidocaine was significantly higher than when bupivacaine, prilocaine and procaine were used. The term "TNS", which implies a positive neurologic finding, should not be used for this painful condition. One study about the impact of TNS on patient satisfaction and functional impairment demonstrated that non-TNS patients were more satisfied and had less functional impairment after surgery than TNS patients, but this did not influence their willingness to recommend spinal anaesthesia.

Review Meta AnalysisSedatives for opiate withdrawal in newborn infants.
Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. ⋯ In newborn infants with NAS, there is no evidence that phenobarbitone compared with supportive care alone reduces treatment failure; however, phenobarbitone may reduce the daily duration of supportive care needed. Phenobarbitone, compared to diazepam, reduces treatment failure. In infants treated with an opiate, the addition of phenobarbitone may reduce withdrawal severity. Further trials are required to determine if this finding is applicable when a higher initial dose of opiate is used, and determine the effects of phenobabritone on infant development. There is insufficient evidence to support the use of chlorpromazine or clonidine in newborn infants with NAS. Clonidine and chlorpromazine should only be used in the context of a randomised clinical trial. This review should be taken in conjunction with the review "Opiate treatment for opiate withdrawal in newborn infants" (Osborn 2002a) which indicates that an opiate is the preferred initial therapy for NAS.
