The worldwide population is aging, and the number of surgeries performed in geriatric patients is increasing. This systematic review evaluated anesthetic procedures to assess global data on perioperative and anesthesia-related cardiac arrest (CA) rates in geriatric surgical patients. Available data on perioperative and anesthesia-related CA rates over time and by the country's Human Development Index (HDI) were evaluated by meta-regression, and a pooled analysis of proportions was used to compare perioperative and anesthesia-related CA rates by HDI and time period. The meta-regression showed that perioperative CA rates did not change significantly over time or by HDI, whereas anesthesia-related CA rates decreased over time (P = 0.04) and in high-HDI (P = 0.015). Perioperative and anesthesia-related CA rates per 10,000 anesthetic procedures declined in high-HDI, from 38.6 before the 1990s to 7.7 from 1990-2017 (P < 0.001) and from 9.2 before the 1990s to 1.3 from 1990-2017 (P < 0.001), respectively. The perioperative CA rate from 1990-2017 was higher in low-HDI than in high-HDI countries (P < 0.001). Hence, a reduction in anesthesia-related CA rates over time was observed. Both perioperative and anesthesia-related CA rates only decreased with a high-HDI between time periods, and perioperative CA rates during 1990-2017 were 4-fold higher with low- compared to high-HDI in geriatric patients.

Meta-Analysis
BACKGROUND
Whether regional anesthesia may help to prevent disease recurrence in cancer patients is still controversial. The stage of cancer at the time of diagnosis is a key factor that defines prognosis and is one of the most important sources of heterogeneity for the treatment effect. We sought to update existing systematic reviews and clarify the effect of regional anesthesia on cancer recurrence in late-stage cancer patients.
METHODS
Medline, Embase, and Cochrane Library were searched from inception to September 2020 to identify randomized controlled trials (RCTs) and cohort studies that assessed the effect of regional anesthesia on cancer recurrence and overall survival (OS) compared with general anesthesia. Late-stage cancer patients were primarily assessed according to the American Joint Committee on Cancer Cancer Staging Manual (eighth edition), and the combined hazard ratio (HR) from random-effects models was used to evaluate the effect of regional anesthesia.
RESULTS
A total of three RCTs and 34 cohort studies (including 64,691 patients) were identified through the literature search for inclusion in the analysis. The risk of bias was low in the RCTs and was moderate in the observational studies. The pooled HR for recurrence-free survival (RFS) or OS did not favor regional anesthesia when data from RCTs in patients with late-stage cancer were combined (RFS, HR = 1.12, 95% confidence interval [CI]: 0.58-2.18, P = 0.729, I2 = 76%; OS, HR = 0.86, 95% CI: 0.63-1.18, P = 0.345, I2 = 48%). Findings from observational studies showed that regional anesthesia may help to prevent disease recurrence (HR = 0.87, 95% CI: 0.78-0.96, P = 0.008, I2 = 71%) and improve OS (HR = 0.88, 95% CI: 0.79-0.98, P = 0.022, I2 = 79%).
CONCLUSIONS
RCTs reveal that OS and RFS were similar between regional and general anesthesia in late-stage cancers. The selection of anesthetic methods should still be based on clinical evaluation, and changes to current practice need more support from large, well-powered, and well-designed studies.

Review
This systematic review of the Brazilian and worldwide literature aims to evaluate the incidence and causes of perioperative and anesthesia-related mortality. Studies were identified by searching the Medline and Scielo databases, followed by a manual search for relevant articles. Our review includes studies published between 1954 and 2007. Each publication was reviewed to identify author(s), study period, data source, perioperative mortality rates, and anesthesia-related mortality rates. Thirty-three trials were assessed. Brazilian and worldwide studies demonstrated a similar decline in anesthesia-related mortality rates, which amounted to fewer than 1 death per 10,000 anesthetics in the past two decades. Perioperative mortality rates also decreased during this period, with fewer than 20 deaths per 10,000 anesthetics in developed countries. Brazilian studies showed higher perioperative mortality rates, from 19 to 51 deaths per 10,000 anesthetics. The majority of perioperative deaths occurred in neonates, children under one year, elderly patients, males, patients of ASA III physical status or poorer, emergency surgeries, during general anesthesia, and cardiac surgery followed by thoracic, vascular, gastroenterologic, pediatric and orthopedic surgeries. The main causes of anesthesia-related mortality were problems with airway management and cardiocirculatory events related to anesthesia and drug administration. Our systematic review of the literature shows that perioperative mortality rates are higher in Brazil than in developed countries, while anesthesia-related mortality rates are similar in Brazil and in developed countries. Most cases of anesthesia-related mortality are associated with cardiocirculatory and airway events. These data may be useful in developing strategies to prevent anesthesia-related deaths.

Regional anaesthesia in children has evolved rapidly in the last decade. Although it previously consisted of primarily neuraxial techniques, the practice now incorporates advanced peripheral nerve blocks, which were only recently described in adults. These novel blocks provide new avenues for providing opioid-sparing analgesia while minimising invasiveness, and perhaps risk, associated with older techniques. At the same time, established methods, such as infant spinal anaesthesia, under-utilised in the last 20 years, are experiencing a revival. The impetus has been the concern regarding the potential long-term neurocognitive effects of general anaesthesia in the young child. These techniques have expanded from single shot spinal anaesthesia to combined spinal/epidural techniques, which can now effectively provide surgical anaesthesia for procedures below the umbilicus for a prolonged period of time, thereby avoiding the need for general anaesthesia. Continuous 2-chloroprocaine infusions, previously only described for intra-operative regional anaesthesia, have gained popularity as a means of providing prolonged postoperative analgesia in epidural and continuous nerve block techniques. The rapid, liver-independent metabolism of 2-chloroprocaine makes it ideal for prolonged local anaesthetic infusions in neonates and small infants, obviating the increased risk of local anaesthetic systemic toxicity that occurs with amide local anaesthetics. Debate continues over certain practices in paediatric regional anaesthesia. While the rarity of complications makes comparative analyses difficult, data from large prospective registries indicate that providing regional anaesthesia to children while under general anaesthesia appears to be at least as safe as in the sedated or awake patient. In addition, the estimated frequency of serious adverse events demonstrates that regional blocks in children under general anaesthesia are no less safe than in awake adults. In infants, the techniques of direct thoracic epidural placement or caudal placement with cephalad threading each have distinct advantages and disadvantages. As the data cannot support the safety of one technique over the other, the site of epidural insertion remains largely a matter of anaesthetist discretion.

OBJECTIVE
Preventing medication errors and improving patient safety in pediatric anesthesia are top priorities. This systematic scoping review was conducted to identify and summarize reports on medication errors in pediatric anesthesia. The study also aimed to qualitatively synthesize medication error situations in pediatric anesthesia and recommendations to eliminate/minimize them.
METHODS
The databases: Cochrane, MEDLINE through PubMed, Embase, CINAHL through EBSCO, and PsycINFO were extensively searched from their inception to March 3, 2020. Error situations in pediatric anesthesia and recommendations to minimize/reduce these errors were synthesized qualitatively. Recommendations were graded by level of evidence using the methodology of the Joanna Briggs Institute.
RESULTS
Data were extracted from 39 publications. Dosing errors were the most commonly reported. Scenarios representing medication (n = 33) error situations in pediatric anesthesia and recommendations to eliminate/minimize medication errors (n = 36) were qualitatively synthesized. Of the recommendations, 2 (5.6%) were related to manufacture, 4 (11.1%) were related to policy, 1 (2.8%) was related to presentation to user, 1 (2.8%) was related to process tools, 17 (47.2%) were related to administration, 3 (8.3%) were related to recording/documentation, and 8 (22.2%) recommendations were classified as others. Of those, 29 (80.6%), 3 (8.3%), 3 (8.3%), and 1 (2.8%) were graded as evidence level 1, 2, 3, and 5, respectively.
DISCUSSION
Medication error situations that might occur in pediatric anesthesia and recommendations on how to eliminate/minimize medication errors were also qualitatively synthesized. Adherence to recommendations might reduce the incidence of medication errors in pediatric anesthesia.

Meta-Analysis
INTRODUCTION
Studies have shown that both perioperative and anesthesia-related cardiac arrest (CA) and mortality rates are much higher in developing countries than in developed countries. This review aimed to compare the rates of perioperative and anesthesia-related CA and mortality during 2 time periods in Brazil.
METHODS
A systematic review with meta-analysis of full-text Brazilian observational studies was conducted by searching the Medline, EMBASE, LILACS and SciELO databases up to January 29, 2020. The primary outcomes were perioperative CA and mortality rates and the secondary outcomes included anesthesia-related CA and mortality events rates up to 48 postoperative hours.
RESULTS
Eleven studies including 719,273 anesthetic procedures, 962 perioperative CAs, 134 anesthesia-related CAs, 1,239 perioperative deaths and 29 anesthesia-related deaths were included. The event rates were evaluated in 2 time periods: pre-1990 and 1990-2020. Perioperative CA rates (per 10,000 anesthetics) decreased from 39.87 (95% confidence interval [CI]: 34.60-45.50) before 1990 to 17.61 (95% CI: 9.21-28.68) in 1990-2020 (P < 0.0001), while the perioperative mortality rate did not alter (from 19.25 [95% CI: 15.64-23.24] pre-1990 to 25.40 [95% CI: 13.01-41.86] in 1990-2020; P = 0.1984). Simultaneously, the anesthesia-related CA rate decreased from 14.39 (95% CI: 11.29-17.86) to 3.90 (95% CI: 2.93-5.01; P < 0.0001), while there was no significant difference in the anesthesia-related mortality rate (from 1.75 [95% CI: 0.76-3.11] to 0.67 [95% CI: 0.09-1.66; P = 0.5404).
CONCLUSIONS
This review demonstrates an important reduction in the perioperative CA rate over time in Brazil, with a large and consistent decrease in the anesthesia-related CA rate; however, there were no significant differences in perioperative and anesthesia-related mortality rates between the assessed time periods.

Review
Neuraxial anaesthesia is widely utilised for elective caesarean section, but the prevalence of inadequate intra-operative anaesthesia is unclear. We aimed to determine the prevalence of inadequate neuraxial anaesthesia for elective caesarean section; prevalence of conversion from neuraxial anaesthesia to general anaesthesia following inadequate neuraxial anaesthesia; and the effect of mode of anaesthesia. We searched studies reporting inadequate neuraxial anaesthesia that used ≥ ED95 doses (effective dose in 95% of the population) of neuraxial local anaesthetic agents. Our primary outcome was the prevalence of inadequate neuraxial anaesthesia, defined as the need to convert to general anaesthesia; the need to repeat or abandon a planned primary neuraxial technique following incision; unplanned administration of intra-operative analgesia (excluding sedatives); or unplanned epidural drug supplementation. Fifty-four randomised controlled trials were included (3497 patients). The overall prevalence of requirement for supplemental analgesia or anaesthesia was 14.6% (95%CI 13.3-15.9%); 510 out of 3497 patients. The prevalence of general anaesthesia conversion was 2 out of 3497 patients (0.06% (95%CI 0.0-0.2%)). Spinal/combined spinal-epidural anaesthesia was associated with a lower overall prevalence of inadequate neuraxial anaesthesia than epidural anaesthesia (10.2% (95%CI 9.0-11.4%), 278 out of 2732 patients vs. 30.3% (95%CI 26.5-34.5%), 232 out of 765 patients). Further studies are needed to identify risk factors, optimise detection and management strategies and to determine long-term effects of inadequate neuraxial anaesthesia.

Review
BACKGROUND AND OBJECTIVES
Anesthesiologists and hospitals are increasingly confronted with costs associated with the complications of Peripheral Nerve Blocks (PNB) procedures. The objective of our study was to identify the incidence of the main adverse events associated with regional anesthesia, particularly during anesthetic PNB, and to evaluate the associated healthcare and social costs.
METHODS
According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic search on EMBASE and PubMed with the following search strategy: ("regional anesthesia" OR "nerve block") AND ("complications" OR "nerve lesion" OR "nerve damage" OR "nerve injury"). Studies on patients undergoing a regional anesthesia procedure other than spinal or epidural were included. Targeted data of the selected studies were extracted and further analyzed.
RESULTS
Literature search revealed 487 articles, 21 of which met the criteria to be included in our analysis. Ten of them were included in the qualitative and 11 articles in the quantitative synthesis. The analysis of costs included data from four studies and 2,034 claims over 51,242 cases. The median claim consisted in 39,524 dollars in the United States and 22,750 pounds in the United Kingdom. The analysis of incidence included data from seven studies involving 424,169 patients with an overall estimated incidence of 137/10,000.
CONCLUSIONS
Despite limitations, we proposed a simple model of cost calculation. We found that, despite the relatively low incidence of adverse events following PNB, their associated costs were relevant and should be carefully considered by healthcare managers and decision makers.

Meta-Analysis
INTRODUCTION
In the last years, spinal anesthesia (SA) has been emerging as an alternative to general anesthesia (GA) for the laparoscopic treatment of gynecological diseases, for better control of postoperative pain. The aim of the review is to compare the advantages of SA compared to GA.
METHODS
MEDLINE, Scopus, ClinicalTrials.gov, EMBASE, Cochrane Library, and CINAHL were searched from inception until March 2021. Randomized controlled trials (RCTs) and non-randomized studies (NRSs) about women underwent SA and GA for gynecological laparoscopic surgery were analyzed. Relevant data were extracted and tabulated.
RESULTS
The primary outcomes included the evaluation of postoperative pain (described as shoulder pain), postoperative nausea and vomiting, and operative times. One hundred and eight patients were included in RCTs, 58 in NRSs. The qualitative analysis had conflicting results and for the most of parameters (hemodynamic variables, nausea, and postoperative analgesic administration) no statistically significant differences were observed: in the NRSs, contradictory results regarding the postoperative pain in SA and GA groups were reported. Regarding the quantitative analysis, in the RCTs, women who received SA had not significantly lower operative times (relative risk [RR] -4.40, 95% confidence interval [CI] -9.32-0.53) and a lower incidence of vomiting (RR 0.51, 95% CI 0.17-1.55); on the other hand, in the NRS, women who received SA had longer operative times (RR 5.05, 95% CI -0.03-10.14) and more episodes of vomiting (RR 0.56, 95% CI 0.10-2.97) compared to those with GA: anyway, the outcomes proved to be insignificant.
CONCLUSIONS
Current evidence suggests no significant advantages to using SA over GA for laparoscopic treatment of gynecological diseases.

Review
We studied the current literature on human patient simulation for preparing anesthesia and other healthcare providers for advanced airway management. A systematic review was conducted of articles published between 1990 and 2009 on advanced airway management for patients undergoing anesthesia and patients who are not. The search used 4 electronic databases: Cumulative Index to Nursing & Allied Health Literature, MEDLINE, PsycINFO, and Web of Science. We included 34 articles in the analysis; 15 were experimental or quasi-experimental designs, 8 descriptive studies and reports, and 11 analyses of equipment or technique evaluations using simulation. The majority of the studies included simulation education evaluation for a variety of medical, nursing, and allied health providers and students. Only 6 studies addressed the use of simulation as an educational or evaluation tool to enhance training of anesthesia providers in difficult airway management. Those studies included analyses of different types of training and the perceived value of simulated training, and evaluations of equipment. Few studies have analyzed the effects of this modality on trainer skills and patient safety. There is a clear need for well-designed studies to examine these effects.
