PloS One 2015To evaluate the efficacy and safety of progesterone administrated in patients with acute traumatic brain injury (TBI). (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To evaluate the efficacy and safety of progesterone administrated in patients with acute traumatic brain injury (TBI).
METHODS
PubMed/MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), Clinicaltrials.gov, ISRCTN registry and WHO International Clinical Trials Registry Platform (ICTRP) were searched for randomized controlled trials (RCTs) comparing progesterone and placebo administrated in acute TBI patients. The primary outcome was mortality and the secondary outcomes were unfavorable outcomes and adverse events. A meta-analysis was conducted to evaluate the efficacy and safety of progesterone administrated in patients with acute TBI.
RESULTS
A total of 6 studies met inclusion criteria, involving 2,476 patients. The risk of bias was considered to be low in 4 studies but high in the other 2 studies. The results of meta-analysis indicated progesterone did not reduce the mortality (RR = 0.83, 95% CI = 0.57-1.20) or unfavorable outcomes (RR = 0.89, 95% CI = 0.78-1.02) of acute TBI patients in comparison with placebo. Sensitivity analysis yielded consistent results. Progesterone was basically safe and well tolerated in TBI patients with the exception of increased risk of phlebitis or thrombophlebitis (RR = 3.03, 95% CI = 1.96-4.66).
CONCLUSIONS
Despite some modest bias, present evidence demonstrated that progesterone was well tolerated but did not reduce the mortality or unfavorable outcomes of adult patients with acute TBI.

Meta-Analysis Review
BACKGROUND
Venous access is an essential part of caring for the sick neonate. However, problems such as contamination of fluids with bacteria, endotoxins and particulates have been associated with intravenous infusion therapy. Intravenous in-line filters claim to be an effective strategy for the removal of bacteria, endotoxins and particulates associated with intravenous therapy in adults and are increasingly being recommended for use in neonates.
OBJECTIVES
To determine the effect of intravenous in-line filters on morbidity and mortality in neonates.
SEARCH METHODS
We used the standard search strategy of the Cochrane Neonatal Review Group. We searched the electronic databases MEDLINE (from 1966 to May, 2015), EMBASE (from 1980 to May, 2015), CINAHL (from 1982 to May 2015) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 5). We did not impose any language restrictions. Further searching included cross references, abstracts, conferences, symposia proceedings, expert informants and journal handsearching.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) or quasi-RCTs that compared the use of intravenous in-line filters with placebo or nothing in neonates.
DATA COLLECTION AND ANALYSIS
We followed the procedures of the Cochrane Neonatal Review Group throughout. We checked titles and abstracts identified from the search. We obtained the full text of all studies of possible relevance. We independently assessed the trials for their methodological quality and subsequent inclusion in the review. We contacted authors for further information as needed. Statistical analysis followed the procedures of the Cochrane Neonatal Review Group.
MAIN RESULTS
There were four eligible studies that recruited a total of 704 neonates. This review of low to very low quality evidence found that the use of in-line filters compared with unfiltered fluids for intravenous infusion had no statistically significant difference in effectiveness on overall mortality (typical RR 0.87, 95% CI 0.52 to 1.47; typical RD -0.01, 95% CI -0.06 to 0.04; two studies, 530 infants), proven and suspect septicaemia (typical RR 0.86, 95% CI 0.59 to 1.27; typical RD -0.02, 95% CI -0.09 to 0.04; two studies, 530 infants), or other secondary outcomes (including local phlebitis and thrombus, necrotising enterocolitis, duration of cannula patency, length of stay in hospital, number of catheters inserted and financial costs).
AUTHORS' CONCLUSIONS
There is insufficient evidence to recommend the use of intravenous in-line filters to prevent morbidity and mortality in neonates.

Meta-Analysis Review
BACKGROUND
A peripheral venous catheter (PVC) is typically used for short-term delivery of intravascular fluids and medications. It is an essential element of modern medicine and the most frequent invasive procedure performed in hospitals. However, PVCs often fail before intravenous treatment is completed: this can occur because the device is not adequately attached to the skin, allowing the PVC to fall out, leading to complications such as phlebitis (irritation or inflammation to the vein wall), infiltration (fluid leaking into surrounding tissues) or occlusion (blockage). An inadequately secured PVC also increases the risk of catheter-related bloodstream infection (CRBSI), as the pistoning action (moving back and forth in the vein) of the catheter can allow migration of organisms along the catheter and into the bloodstream. Despite the many dressings and securement devices available, the impact of different securement techniques for increasing PVC dwell time is still unclear; there is a need to provide guidance for clinicians by reviewing current studies systematically.
OBJECTIVES
To assess the effects of PVC dressings and securement devices on the incidence of PVC failure.
SEARCH METHODS
We searched the following electronic databases to identify reports of relevant randomised controlled trials (RCTs): the Cochrane Wounds Group Register (searched 08 April 2015): The Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 3), Ovid MEDLINE (1946 to March 7 2015); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, March 7 2015); Ovid EMBASE (1974 to March 7 2015); and EBSCO CINAHL (1982 to March 8 2015).
SELECTION CRITERIA
RCTs or cluster RCTs comparing different dressings or securement devices for the stabilisation of PVCs. Cross-over trials were ineligible for inclusion, unless data for the first treatment period could be obtained.
DATA COLLECTION AND ANALYSIS
Two review authors independently selected studies, assessed trial quality and extracted data. We contacted study authors for missing information. We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
We included six RCTs (1539 participants) in this review. Trial sizes ranged from 50 to 703 participants. These six trials made four comparisons, namely: transparent dressings versus gauze; bordered transparent dressings versus a securement device; bordered transparent dressings versus tape; and transparent dressing versus sticking plaster. There is very low quality evidence of fewer catheter dislodgements or accidental removals with transparent dressings compared with gauze (two studies, 278 participants, RR 0.40; 95% CI 0.17 to 0.92, P = 0.03%). The relative effects of transparent dressings and gauze on phlebitis (RR 0.89; 95% CI 0.47 to 1.68) and infiltration (RR 0.80; 95% CI 0.48 to 1.33) are unclear. The relative effects on PVC failure of a bordered transparent dressing and a securement device have been assessed in only one small study and these were unclear. There was very low quality evidence from the same single study of less frequent dislodgement or accidental catheter removal with bordered transparent dressings than securement devices (RR 0.14, 95% CI 0.03 to 0.63) but more phlebitis with bordered dressings (RR 8.11, 95% CI 1.03 to 64.02) (very low quality evidence). A small single study compared bordered transparent dressings with tape and found very low quality evidence of more PVC failure with the bordered dressing (RR 1.84, 95% CI 1.08 to 3.11) but the relative effects on dislodgement were not clear (very low quality evidence). The relative effects of transparent dressings and a sticking plaster have only been compared in one small study and are unclear. More high quality RCTs are required to determine the relative effects of alternative PVC dressings and securement devices.
AUTHORS' CONCLUSIONS
It is not clear if any one dressing or securement device is better than any other in securing peripheral venous catheters. There is a need for further, independent high quality trials to evaluate the many traditional as well as the newer, high use products. Given the large cost differences between some different dressings and securement devices, future trials should include a robust cost-effectiveness analysis.

Meta-Analysis Review
BACKGROUND
Dehydration is an important cause of death in patients with Ebola virus disease (EVD). Parenteral fluids are often required in patients with fluid requirements in excess of their oral intake. The peripheral intravenous route is the most commonly used method of parenteral access, but inserting and maintaining an intravenous line can be challenging in the context of EVD. Therefore it is important to consider the advantages and disadvantages of different routes for achieving parenteral access (e.g. intravenous, intraosseous, subcutaneous and intraperitoneal).
OBJECTIVES
To compare the reliability, ease of use and speed of insertion of different parenteral access methods.
SEARCH METHODS
We ran the search on 17 November 2014. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily, Ovid MEDLINE(R) and Ovid OLDMEDLINE(R), Embase Classic + Embase (OvidSP), CINAHL (EBSCOhost), clinicaltrials.gov and screened reference lists.
SELECTION CRITERIA
Randomised controlled trials comparing different parenteral routes for the infusion of fluids or medication.
DATA COLLECTION AND ANALYSIS
Two review authors examined the titles and abstracts of records obtained by searching the electronic databases to determine eligibility. Two review authors extracted data from the included trials and assessed the risk of bias. Outcome measures of interest were success of insertion; time required for insertion; number of insertion attempts; number of dislodgements; time period with functional access; local site reactions; clinicians' perception of ease of administration; needlestick injury to healthcare workers; patients' discomfort; and mortality. For trials involving the administration of fluids we also collected data on the volume of fluid infused, changes in serum electrolytes and markers of renal function. We rated the quality of the evidence as 'high', 'moderate', 'low' or 'very low' according to the GRADE approach for the following outcomes: success of insertion, time required for insertion, number of dislodgements, volume of fluid infused and needlestick injuries.
MAIN RESULTS
We included 17 trials involving 885 participants. Parenteral access was used to infuse fluids in 11 trials and medications in six trials. None of the trials involved patients with EVD. Intravenous and intraosseous access was compared in four trials; intravenous and subcutaneous access in 11; peripheral intravenous and intraperitoneal access in one; saphenous vein cutdown and intraosseous access in one; and intraperitoneal with subcutaneous access in one. All of the trials assessing the intravenous method involved peripheral intravenous access.We judged few trials to be at low risk of bias for any of the assessed domains.Compared to the intraosseous group, patients in the intravenous group were more likely to experience an insertion failure (risk ratio (RR) 3.89, 95% confidence interval (CI) 2.39 to 6.33; n = 242; GRADE rating: low). We did not pool data for time to insertion but estimates from the trials suggest that inserting intravenous access takes longer (GRADE rating: moderate). Clinicians judged the intravenous route to be easier to insert (RR 0.15, 95% CI 0.04 to 0.61; n = 182). A larger volume of fluids was infused via the intravenous route (GRADE rating: moderate). There was no evidence of a difference between the two routes for any other outcomes, including adverse events.Compared to the subcutaneous group, patients in the intravenous group were more likely to experience an insertion failure (RR 14.79, 95% CI 2.87 to 76.08; n = 238; GRADE rating: moderate) and dislodgement of the device (RR 3.78, 95% CI 1.16 to 12.34; n = 67; GRADE rating: low). Clinicians also judged the intravenous route as being more difficult to insert and patients were more likely to be agitated in the intravenous group. Patients in the intravenous group were more likely to develop a local infection and phlebitis, but were less likely to develop erythema, oedema or swelling than those in the subcutaneous group. A larger volume of fluids was infused into patients via the intravenous route. There was no evidence of a difference between the two routes for any other outcome.There were insufficient data to reliably determine if the risk of insertion failure differed between the saphenous vein cutdown (SVC) and intraosseous method (RR 4.00, 95% CI 0.51 to 31.13; GRADE rating: low). Insertion using SVC took longer than the intraosseous method (MD 219.60 seconds, 95% CI 135.44 to 303.76; GRADE rating: moderate). There were no data and therefore there was no evidence of a difference between the two routes for any other outcome.There were insufficient data to reliably determine the relative effects of intraperitoneal or central intravenous access relative to any other parenteral access method.
AUTHORS' CONCLUSIONS
There are several different ways of achieving parenteral access in patients who are unable meet their fluid requirements with oral intake alone. The quality of the evidence, as assessed using the GRADE criteria, is somewhat limited because of the lack of adequately powered trials at low risk of bias. However, we believe that there is sufficient evidence to draw the following conclusions: if peripheral intravenous access can be achieved easily, this allows infusion of larger volumes of fluid than other routes; but if this is not possible, the intraosseous and subcutaneous routes are viable alternatives. The subcutaneous route may be suitable for patients who are not severely dehydrated but in whom ongoing fluid losses cannot be met by oral intake.A film to accompany this review can be viewed here (http://youtu.be/ArVPzkf93ng).
