Review Meta AnalysisLong- or short-acting opioids for chronic non-malignant pain? A qualitative systematic review.
In selected patients with chronic non-malignant pain, chronic opioid therapy is indicated. Published guidelines recommend long-acting over short-acting opioids in these patients. The aim of this systematic review was to investigate whether long-acting opioids in chronic non-malignant pain are superior to short-acting opioids in pain relief, physical function, sleep quality, quality of life or adverse events. ⋯ Three trials in healthy volunteers with a recreational drug use, found no difference in abuse potential between long- and short-acting opioids. While long term, comparative data are lacking, there is fair evidence from short-term trials that long-acting opioids provide equal pain relief compared with short-acting opioids. Contrary to several guidelines, there is no evidence supporting long-acting opioids superiority to short-acting ones in improving functional outcomes, reducing side effects or addiction.

Review Meta AnalysisPost-operative analgesic effects of paracetamol, NSAIDs, glucocorticoids, gabapentinoids and their combinations: a topical review.
In contemporary post-operative pain management, patients are most often treated with combinations of non-opioid analgesics, to enhance pain relief and to reduce opioid requirements and opioid-related adverse effects. A diversity of combinations is currently employed in clinical practice, and no well-documented 'gold standards' exist. The aim of the present topical, narrative review is to provide an update of the evidence for post-operative analgesic efficacy with the most commonly used, systemic non-opioid drugs, paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs)/COX-2 antagonists, glucocorticoids, gabapentinoids, and combinations of these. ⋯ Paracetamol, NSAIDs, selective COX-2 antagonists, and gabapentin all seem to have well-documented, clinically relevant analgesic properties. The analgesic effects of glucocorticoids and pregabalin await further clarification. Combination regimens are sparsely documented and should be further investigated in future studies.

Review Meta Analysis
Effect of combining tramadol and morphine in adult surgical patients: a systematic review and meta-analysis of randomized trials.
The role for tramadol in multimodal postsurgical analgesic strategies remains unclear. We undertook a systematic review to evaluate the utility of combining tramadol with morphine after surgery. We searched the MEDLINE, EMBASE, LILAC, Cochrane, and Clinical Trial Register databases for randomized, controlled studies comparing tramadol with placebo or active control in patients undergoing surgery. ⋯ No difference in the incidence of nausea, vomiting, sedation, or shivering was observed. There was no decrease in pain intensity at 24 h; the WMD was -0.9 (-7.2; 5.2) on a 100 mm visual analogue scale at 24 h. We found no significant clinical benefit from the combination of i.v. tramadol and morphine after surgery.

Review Meta AnalysisPreventive analgesia by local anesthetics: the reduction of postoperative pain by peripheral nerve blocks and intravenous drugs.
Barreveld et al. show that LA administered either IV or via block; before, during or after surgery, significantly reduces postoperative pain and opioid consumption.
Specifically in:
- Total knee arthroplasty (femoral, sciatic and lumbar plexus b., single-shot or continuous)
- Total hip arthroplasty (continuous lumbar plexus; intra-articular LA)
- Knee arthroscopy (single-shot lumbar plexus; IA LA; single-shot femoral nerve ± sciatic).
- Arthroscopic shoulder surgery - interscalene b., single-shot or continuous. IA is not beneficial.
- Hand & forearm surgery - axillary b. offers analgesic benefits only on day of surgery.
- TAP block is beneficial for laparoscopic, open appendectomy, abdominal surgery, cesarean section, and TAH.

Review Meta Analysis
THE PERIOPERATIVE USE OF PREGABALIN FOR ACUTE PAIN- A SYSTEMATIC REVIEW AND META- ANALYSIS.
Evidence supporting postoperative pain management using pregabalin as an adjunct intervention across various surgical pain models is lacking. The objective of this systematic review was to evaluate "model-specific" comparative effectiveness and harms of pregabalin following a previously published systematic review protocol. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched from inception through August 2013. ⋯ Pregabalin analgesic effectiveness is largely restricted to surgical procedures associated with pronociceptive mechanisms. The clinical significance of observed pregabalin benefits must be weighed against the uncertainties about serious harms and enhanced recovery to inform the careful selection of surgical patients. Recommendations for future research are proposed.

Meta Analysis
Single-dose Systemic Acetaminophen to Prevent Postoperative Pain: A Meta-analysis of Randomized Controlled Trials.
The effect of a single-dose systemic acetaminophen to treat postoperative pain has been previously quantified, but the effect of systemic acetaminophen to prevent postoperative pain is currently not well defined. The preventive analgesic effect of acetaminophen has yet to be quantified in a meta-analysis. The objective of the current investigation was to evaluate the effect of a single preventive dose of systemic acetaminophen on postoperative pain outcomes. ⋯ Systemic acetaminophen, when used as a single-dose preventive regimen, is an effective intervention to reduce postoperative pain. It also reduces postoperative nausea and/or vomiting. Doses >1 g were not associated with greater reduction in pain outcomes.

Review Meta Analysis
Effect of perioperative systemic α2 agonists on postoperative morphine consumption and pain intensity: systematic review and meta-analysis of randomized controlled trials.
Systemic α2 agonists are believed to reduce pain and opioid requirements after surgery, thus decreasing the incidence of opioid-related adverse effects, including hyperalgesia. ⋯ Perioperative systemic α2 agonists decrease postoperative opioid consumption, pain intensity, and nausea. Recovery times are not prolonged. Common adverse effects are bradycardia and arterial hypotension. The impact of α2 agonists on chronic pain or hyperalgesia remains unclear because valid data are lacking.

Review Meta Analysis
The efficacy of lidocaine to prevent laryngospasm in children: a systematic review and meta-analysis.
The purpose of this meta-analysis was to determine the efficacy of lidocaine in preventing laryngospasm during general anaesthesia in children. An electronic search of six databases was conducted. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were adhered to. ⋯ Subgroup analysis revealed that both intravenous lidocaine (RR 0.34, 95% CI 0.14-0.82) and topical lidocaine (RR 0.42, 95% CI 0.22-0.80) lidocaine are effective in preventing laryngospasm. The results were not affected by studies with a high risk of bias. We conclude that, both topical and intravenous lidocaine are effective for preventing laryngospasm in children.

ReviewAdverse effects of perioperative paracetamol, NSAIDs, glucocorticoids, gabapentinoids and their combinations: a topical review.
Post-operative pain affects millions of patients worldwide and the post-operative period has high rates of morbidity and mortality. Some of this morbidity may be related to analgesics. The aim of this review was to provide an update of current knowledge of adverse events (AE) associated with the most common perioperative non-opioid analgesics: paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), glucocorticoids (GCCs), gabapentinoids and their combinations. ⋯ Importantly, data on AEs of combinations of the above analgesics are sparse and inconclusive. Despite the potential adverse events associated with the most commonly applied non-opioid analgesics, including their combinations, reporting of such events is sparse and confined to the immediate perioperative period. Knowledge of benefit and harm related to multimodal pain treatment is deficient and needs clarification in large trials with prolonged observation.

ReviewOutcome after regional anesthesia: weighing risks and benefits.
Regional anesthesia has become a widely used method to provide intraoperative anesthesia, and postoperative analgesia. This review seeks to address the question whether patient outcomes are improved to an extent that justifies using regional anesthesia as a routine method. During the past decade, a very critical appraisal of risks and benefits of regional anesthetic procedures has taken place. ⋯ A substantial share of the beneficial effects of regional anesthesia on the immune system, hemostasis, pain, and the duration of ileus can be duplicated using intravenous administration of local anesthetics. In general, the use of regional anesthesia should always be preceded by a weighing of potential risks and proven benefits. Regional anesthesia continues to play a major role in perioperative medicine, but its role keeps getting more defined and less non-committal.

ReviewSystemic lidocaine in surgical procedures: effects beyond sodium channel blockade.
This review presents current data on the systemic administration of lidocaine. The focus is on studies in the perioperative setting. In addition, there is a brief look at experimental data on the effect of lidocaine at the molecular level. ⋯ Positive effects on postoperative pain, as well as on bowel motility and hospital discharge time, have regularly been observed. However, contradictory findings have also been published. As almost all of the studies only include very small patient numbers, large multicenter investigations are needed.

Review Meta Analysis
Perioperative intravenous lidocaine infusion for postoperative pain control: a meta-analysis of randomized controlled trials.
Various strategies have been proposed for postoperative pain control. Among those, intravenous lidocaine infusion (IVLI) has gained in interest. However, its clinical benefit remains unclear. This systematic review is an evaluation of the analgesic efficacy and safety of IVLI during general anesthesia. ⋯ Perioperative IVLI reduced postoperative pain and opioid requirement, as well as ileus recovery time, hospital length of stay, and nausea/vomiting. Intravenous lidocaine infusion was effective mainly in abdominal surgery populations. Considering that toxic levels were detected and that adverse events were not systematically screened for in most studies, dose and safety of IVLI should be established before recommending its use.

Review Meta AnalysisThe prevention of chronic postsurgical pain using gabapentin and pregabalin: a combined systematic review and meta-analysis.
Many clinical trials have demonstrated the effectiveness of gabapentin and pregabalin administration in the perioperative period as an adjunct to reduce acute postoperative pain. However, very few clinical trials have examined the use of gabapentin and pregabalin for the prevention of chronic postsurgical pain (CPSP). We (1) systematically reviewed the published literature pertaining to the prevention of CPSP (≥ 2 months after surgery) after perioperative administration of gabapentin and pregabalin and (2) performed a meta-analysis using studies that report sufficient data. A search of electronic databases (Medline, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, IPA, and CINAHL) for relevant English-language trials to June 2011 was conducted. ⋯ The present review supports the view that perioperative administration of gabapentin and pregabalin are effective in reducing the incidence of CPSP. Better-designed and appropriately powered clinical trials are needed to confirm these early findings.

We present the main findings of the 5th National Audit Project (NAP5) on accidental awareness during general anaesthesia (AAGA). Incidences were estimated using reports of accidental awareness as the numerator, and a parallel national anaesthetic activity survey to provide denominator data. The incidence of certain/probable and possible accidental awareness cases was ~1:19,600 anaesthetics (95% confidence interval 1:16,700-23,450). ⋯ The following factors were not risk factors for accidental awareness: ASA physical status, race, and use or omission of nitrous oxide. We recommend that an anaesthetic checklist, to be an integral part of the World Health Organization Safer Surgery checklist, is introduced as an aid to preventing accidental awareness. This paper is a shortened version describing the main findings from NAP5--the full report can be found at http://www.nationalauditprojects.org.uk/NAP5_home.

Meta AnalysisThe impact of prophylactic intravenous lidocaine on opioid-induced cough: a meta-analysis of randomized controlled trials.
Opioids are commonly used for general anesthesia, but reflex cough can occur after an intravenous injection. We have performed a meta-analysis of randomized controlled trials (RCTs) that evaluated the effectiveness and safety of prophylactic lidocaine administered intravenously (IV) on opioid-induced cough (OIC) during induction in patients undergoing general anesthesia. ⋯ Our meta-analysis establishes the effectiveness of prophylactic lidocaine administered IV for the prevention of OIC during induction. The lowest effective dose of lidocaine on the risk of OIC appeared to be 0.5 mg/kg.

Intravenous lidocaine infusion has been shown to reduce postoperative pain among patients undergoing abdominal surgery. This study aimed to evaluate the effects of perioperative lidocaine administration in breast surgery. ⋯ The results indicate no significant benefits of intravenous lidocaine infusion in terms of acute postoperative pain. Although lidocaine seems to attenuate the risk of chronic pain after breast surgery, there is insufficient evidence to conclude that lidocaine infusion is of proved benefit because the results were based on a limited number of small trials.

Review Meta Analysis
Peri-operative intravenous administration of magnesium sulphate and postoperative pain: a meta-analysis.
Intravenous magnesium has been reported to improve postoperative pain; however, the evidence is inconsistent. The objective of this quantitative systematic review is to evaluate whether or not the peri-operative administration of intravenous magnesium can reduce postoperative pain. ⋯ Numeric pain scores at rest and on movement at 24 h postoperatively were reduced by 4.2 (95% CI -6.3 to -2.1; p < 0.0001) and 9.2 (95% CI -16.1 to -2.3; p = 0.009) out of 100, respectively. We conclude that peri-operative intravenous magnesium reduces opioid consumption, and to a lesser extent, pain scores, in the first 24 h postoperatively, without any reported serious adverse effects.

ReviewMagnesium as an adjuvant to postoperative analgesia: a systematic review of randomized trials.
Randomized trials have reached different conclusions as to whether magnesium is a useful adjuvant to postoperative analgesia. ⋯ These trials do not provide convincing evidence that perioperative magnesium may have favorable effects on postoperative pain intensity and analgesic requirements. Perioperative magnesium supplementation prevents postoperative hypomagnesemia and decreases the incidence of postoperative shivering. It may be worthwhile to further study the role of magnesium as a supplement to postoperative analgesia, since this relatively harmless molecule is inexpensive, and the biological basis for its potential antinociceptive effect is promising.

The association of body mass index with difficult tracheal intubation management by direct laryngoscopy: a meta-analysis.
Obesity is a serious disorder and may bring about many difficulties of perioperative management. A systematic review was conducted to assess the association between obesity and difficult intubation. ⋯ Obesity was associated with an increased risk of difficult intubation, difficult laryngoscopy and Mallampati score ≥ 3 in adults patients undergoing general surgical procedures. However, there were no association of obesity and risks of difficult intubation compared with non-obesity in the cohort studies and the elective tracheal intubation, no associated with an increased risk of difficult laryngoscopy in the sniffing position. Future analyses should explore the association of BMI and difficult airway.
