Challenges of Pediatric Anesthesia Services and Training Infrastructure in Tertiary Care Teaching Institutions in Pakistan: A Perspective From the Province of Sindh.

BACKGROUND: Pakistan is a lower middle-income country located in South Asia with a population of nearly 208 million. Sindh is its second largest province. The aim of this survey was to identify the current setup of pediatric services, staffing, equipment, and training infrastructure in the teaching hospitals of Sindh. METHODS: The survey was conducted between June 2018 and September 2018. A questionnaire was designed with input from experts and pretested. One faculty coordinator from each of 12 of the 13 teaching hospitals (7 government and 5 private) completed the form. Information was exported into Statistical Package for the Social Sciences (SPSS) version 22. Frequency and percentages were computed for all variables. Confidentiality was ensured by anonymizing the data. RESULTS: Anesthesia services are provided by consultants with either membership or fellowship in anesthesia of the College of Physicians and Surgeons of Pakistan (CPSP). All drugs on the World Health Organization (WHO) essential medication list were available, although narcotic supply was often inconsistent. Weak areas identified were absence of standardization of practice regarding premedication, preoperative laboratory testing, pain assessment, and management. No national practice guidelines exist. Pulse oximeters and capnometers were available in all private hospitals but in only 86% and 44% of the government hospitals, respectively. Some training centers were not providing the training as outlined by the CPSP criteria. CONCLUSIONS: Several gaps have been identified in the practice and training infrastructure of pediatric anesthesia. There is a need for national guidelines, standardization of protocols, provision of basic equipment, and improved supervision of trainees. One suggestion is to have combined residency programs between private and government hospitals to take advantage of the strengths of both. Recommendations by this group have been shared with all teaching hospitals and training bodies.

A study comparing the effect of premedication with intravenous midazolam or dexmedetomidine on ketamine-fentanyl sedoanalgesia in burn patients: A randomized clinical trial.

INTRODUCTION: Dressing changes and wound care-debridement procedures often cause fear and anxiety in burn patients, as these processes are quite painful. In order to determine the best method for alleviating pain during these procedures, the current study compared the efficacy and safety of intravenous dexmedetomidine and midazolam for premedication prior to these painful burn care procedures. METHODS: This comparative and randomized study included patients who had a burn size of 1563%, were aged 1870 years, were diagnosed with the American Society of Anesthesiologists physical status (ASA I-II), and who underwent painful burn care procedures. Patients were intravenously administered either 1 mcg/kg dexmedetomidine (Group 1) or 0.03 mg/kg midazolam (Group 2) prior to the burn care procedure. Recorded at predetermined time points for each patient were heart rhythm (HR), mean arterial pressure (MAP), peripheral oxygen saturation (SpO2), standard bispectral index (BIS), and Ramsay Sedation Scale (RSS). RESULTS: In the dexmedetomidine group, HR and MAP measurements of patients ​​at the 3rd, 5th, and 10th mins during sedation were significantly lower than the baseline values (p < 0.05). A significant decrease in SpO2 was observed in both groups at the 10th min during sedation, but the decline was higher in the midazolam group (p < 0.05). BIS measurements of the patients in both groups were significantly lower at 10 min. during sedation and at 15th and 60th mins during the procedure (p < 0.05). However, there was no significant difference between the group (p > 0.05). The RSS scales of both groups in during the sedation were higher in the 3rd, 5th and 10th mins than the baseline values (p < 0.05), but there was no significant difference between the groups (p > 0.05). The RSS scales of groups in during the burn procedure were significantly higher at 15 th min than the 0 th values, while the RSS scales of both groups were significantly lower in the 45th and 60th mins (p < 0.05). CONCLUSION: Results of this study indicate that dexmedetomidine causes hemodynamic alterations while midazolam causes respiratory depression. However, these effects are not severe, and we conclude that both agents are safe and effective to ensure sedation prior to painful burn-care procedures.

Overuse of venous thromboembolism prophylaxis among hospitalized patients with liver disease.

INTRODUCTION: Patients with liver disease are at risk of venous thromboembolism (VTE); however, little is understood regarding the safety and efficacy of VTE prophylaxis in patients with cirrhosis. We examined the application of a VTE risk assessment model in VTE prophylaxis decision-making in a closed cohort of hospitalized patients with liver disease. METHODS: Sequential patients admitted to an inpatient hepatology service at a tertiary care center were evaluated for need for VTE prophylaxis. Risk assessment by IMPROVE was compared with current practice patterns of VTE prophylaxis. Rates of bleeding and clotting events were noted. RESULTS: 98 patient encounters were included in our analysis. 76% of patients received VTE prophylaxis in practice. IMPROVE recommended use of VTE prophylaxis in 19% of patients. Patients who received VTE prophylaxis that was not warranted had significantly lower risk of clotting compared with patients in whom VTE prophylaxis was warranted per IMPROVE. CONCLUSIONS: Application of IMPROVE risk assessment would significantly reduce VTE prophylaxis use among hospitalized patients with liver disease. Our findings challenge the "one-size-fits-all" current practice pattern of VTE prophylaxis. Future studies are needed in large cohorts of hospitalized patients with liver disease that include clinical outcomes of bleeding and clotting risk.

An overview on the methodological and reporting quality of dose-response meta-analysis on cancer prevention.

BACKGROUND: Dose-response meta-analysis (DRMA) has been widely used in exploring cancer risk factors. Understanding the quality of published DRMAs on cancer risk factors may be beneficial for informed prevention for cancer. METHODS: We searched eligible DRMAs from 1st January 2011 to 31st-July-2017. The modified AMSTAR 1.0 (15 items) and PRISMA checklist (26 items) were used to evaluate the methodological and reporting quality of included DRMAs. We compared the adherence rate of these items by journal type, publication years, region, and funding information, in prior. RESULTS: We included 260 DRMAs. Colorectal, breast, prostate, and lung were the four most commonly investigated cancers. For methodological quality, 6 out of 15 items were adhered by less than 30% of the DRMAs, 2 by less than 60%, only 7 of which by 80% or more. For reporting quality, 3 out of 26 items were adhered by less than 30% of the DRMAs, 1 by less than 80% (> 30%), and 20 of which by 80% or more. Those published in general journal, published more recently, and received any financial support have better methodological (Rate differences, RDs = 10-36%; P < 0.05) and reporting adherence (RDs = 12-36%; P < 0.05). DRMAs by Asian author tend to be less qualified than by European and American. CONCLUSIONS: The methodological quality of DRMAs on cancer risk factors is worrisome that the findings of them may be deflective; more efforts are needed to improve the validity of it.

Evaluation of an Intubation Readiness Score to Assess Neonatal Sedation before Intubation.

BACKGROUND: Premedication for neonatal intubation facilitates the procedure and reduces stress and physiological disturbances. However, no validated scoring system to assess the effect of premedication prior to intubation is available. OBJECTIVE: To evaluate the usefulness of an Intubation Readiness Score (IRS) to assess the effect of premedication prior to intubation in newborn infants. METHODS: Two-center prospective study in neonates who needed endotracheal intubation. Intubation was performed using a standardized procedure with propofol 1-2 mg/kg as premedication. The level of sedation was assessed with the IRS by evaluating the motor response to a firm stimulus (1 = spontaneous movement; 2 = movement on slight touch; 3 = movement on firm stimulus; 4 = no movement). Intubation was proceeded if an adequate effect, defined as an IRS of 3 or 4, was reached. IRS was compared to the quality of intubation measured with the Viby-Mogensen intubation score. RESULTS: A total of 115 patients, with a median gestational age of 27.7 weeks (interquartile range 5.3) and a median birth weight of 1,005 g (interquartile range 940), were included. An adequate IRS was achieved in 105 patients, 89 (85%) of whom also had a good Viby-Mogensen intubation score and 16 (15%) had an inadequate Viby-Mogensen intubation score. The positive predictive value of the IRS was 85%. CONCLUSIONS: Preintubation sedation assessment using the IRS can adequately predict optimal conditions during intubation in the majority of neonates. We suggest using the IRS in routine clinical care. Further research combining the IRS with other parameters could further improve the predictability of adequate sedation during intubation.

[Graft reinjection: Guidelines from the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)]. / Réinjection du greffon : recommandations de la Société francophone de greffe de moelle et de thérapie cellulaire (SFGM-TC).

JACIE (Joint Accreditation Committee ISTC EBMT) regulations and standards impose a quality and safety requirement for graft reinjection by nurses. However, the standards do not provide a step-by-step graft reinjection procedure. Because of high medical team turnover, the opening of new transplant centers, and continual questions from colleagues trying to decipher the JACIE standards, the need for a specific procedure goes without saying. We collected graft reinjection procedures from each SFGM-TC center that participated in our survey, thus creating an inventory of the different steps that make up graft reinjection. In addition to reviewing the main regulatory texts and JACIE standards, we sought advice from medical and cellular therapy experts. We observed that most centers use a mix of practices and some unjustified practices. In some transplant units, it is still standard practice to defrost cell therapy products in the transplant unit. Caregivers are aware of the need for a rigorous application of the regulatory requirements and are willing to administer a procedure that provides specific steps for each stage of the process. In this workshop, we questioned each stage of the graft reinjection procedure, which helped us define clear methods of implementation. In the form of a checklist, we offer bone marrow and stem cell transplant units a step-by-step procedure.

Premedication for Endotracheal Intubation in the Neonate.

Endotracheal intubation, a common procedure in neonatal intensive care, results in distress and disturbs physiologic homeostasis in the newborn. Analgesics, sedatives, vagolytics, and/or muscle relaxants have the potential to blunt these adverse effects, reduce the duration of the procedure, and minimize the number of attempts necessary to intubate the neonate. The medical care team must understand efficacy, safety, and pharmacokinetic data for individual medications to select the optimal cocktail for each clinical situation. Although many units utilize morphine for analgesia, remifentanil has a superior pharmacokinetic profile and efficacy data. Because of hypotensive effects in preterm neonates, sedation with midazolam should be restricted to near-term and term neonates. A vagolytic, generally atropine, blunts bradycardia induced by vagal stimulation. A muscle relaxant improves procedural success when utilized by experienced practitioners; succinylcholine has an optimal pharmacokinetic profile, but potentially concerning adverse effects; rocuronium may be the agent of choice based on more robust safety data despite a relatively prolonged duration of action. In the absence of an absolute contraindication, neonates should receive analgesia with consideration of sedation, a vagolytic, and a muscle relaxant before endotracheal intubation. Neonatal units must develop protocols for premedication and optimize logistics to ensure safe and timely administration of appropriate agents.

Clinical Factors Associated With Adherence to the Premedication Protocol for Withdrawal of Mechanical Ventilation in Terminally Ill Patients: A 4-Year Experience at a Single Medical Center in Asia.

PURPOSE: Data on end-of-life care practices in Asia are scarce. This study aimed to analyze the clinical factors associated with the recommended premedication protocol for mechanical ventilation withdrawal, in Taiwan. METHODS: A total of 135 terminally ill patients who had mechanical ventilation withdrawn between 2013 and 2016 from a single medical center in Taiwan were enrolled. A premedication protocol of morphine and midazolam intravenous bolus was routinely recommended for the patients before mechanical ventilation withdrawal. Receipt of opioids and/or benzodiazepines during the withdrawal process was defined as full (both), partial (1 drug), and no (none) adherence. The clinical factors relevant to the adherence of recommended premedication protocol for mechanical ventilation withdrawal were analyzed. RESULTS: Overall, 126 (93.3%) patients died, 8 (5.9%) patients were transferred to other institutions for further care, and 1 (0.7%) patient was discharged to home after mechanical ventilation withdrawal. The median survival time was 45 minutes, and 102 (75.6%) patients died within 1 day after the withdrawal process. The full, partial, and no adherence rates for premedication guideline were 17.8%, 40.0%, and 42.2%, respectively. The main diagnosis of cancer, receipt of hospice care, and preservation of spontaneous respiration were independent variables associated with the partial or full adherence to the premedication protocol. CONCLUSION: Our data show that adherence to the premedication protocol for mechanical ventilation withdrawal in terminally ill patients was inadequate in Taiwan. Promoting hospice care and educating medical personnel in the compassionate withdrawal of mechanical ventilation, especially in patients with noncancer disease, are warranted.

[A survey on premedication prior to intubation in very preterm infants (28-32WG) with respiratory distress syndrome in French neonatal intensive care units]. / Enquête nationale sur la sédation-analgésie pour intubation des grands prématurés atteints de détresse respiratoire en dehors de l'arrêt cardiorespiratoire et de la salle de naissance.

INTRODUCTION/OBJECTIVES: Tracheal intubation is a painful procedure for which the routine use of analgesia is recommended. However, the use of premedication for intubation is not yet generalized and there is great diversity in the drugs used. The main objective of this study was to describe the frequency of premedication use in preterm neonates aged between 28 and 32weeks of gestation, intubated for respiratory distress syndrome. Secondary objectives were to describe the existence of a written protocol, its influence on the frequency of premedication and the drugs used. MATERIALS AND METHODS: Declarative survey on Google.docs forms addressed to physicians and residents working in neonatal intensive care units in France. RESULTS: One hundred thirty respondents from 64 units completed this survey between 1 June and 31 July 2014. Fifty-seven percent of respondents declared always using a premedication, and 64 % of participants had a written protocol in their units. Persons working in a unit with a written protocol more frequently reported using premedication (P=0.04). The drugs used were various (mostly a hypnotic/morphine combination) and their dosages scattered. DISCUSSION: The results found by this survey confirm data from the literature and the situation seems to have stagnated over the last few years. A written protocol might encourage premedication use. CONCLUSION: Improvements in practices and increased knowledge are required to generalize the sedation/analgesia practices for tracheal intubation in neonatal intensive care units in France.

Use of Clinical Decision Support to Increase Premedication Regimen Homogeneity.

PURPOSE: Patients with prior allergic reactions to iodinated contrast require premedication. This study aimed to increase the homogeneity of premedication orders in such patients. METHODS: A point-of-care (POC) clinical decision support (CDS) alert accompanied by an order set was implemented in the electronic health record (EHR) to notify providers of a prior allergic reaction upon ordering an examination involving iodinated contrast. Premedication regimens were retrospectively compared 11 months pre- and 11 months post-alert implementation, with the different regimens being classified as follows: (1) "preferred" (per ACR recommendations), (2) "nonpreferred" (corticosteroid administered <24 hours before examination, but not per ACR recommendations), or (3) "no premedication." RESULTS: Over 22 months, 22,023 iodinated contrast examinations were performed, 200 (186 intravascular, 12 gastrointestinal/genitourinary, 1 intraarticular, 1 intrathecal) being in patients with a documented iodinated contrast allergy (106 pre-, 94 post-alert deployment). Prealert, 41 of 106 patients (38.7%) received a preferred regimen, 47 (44.3%) received nonpreferred regimens, and 18 (17.0%) received no premedication. Postalert, 58 of 94 patients (61.7%) received a preferred regimen, 21 (22.3%) nonpreferred regimens, and 15 (16.0%) no premedication. After alert initiation, the patients prescribed a preferred regimen significantly increased (Z-score = 3.25, P = .001), but there was no significant difference in the proportion of patients with no premedication (Z-score = -0.02, P = .85). In 2 of 200 patients (1.0%), an allergic reaction occurred, both after POC-CDS alert implementation with a preferred regimen administered. CONCLUSIONS: The homogeneity of premedication regimens significantly increased after the alert's launch. However, the proportion of patients with no premedication did not significantly change.

[Modalities for preparation, cryopreservation, thawing of hematopoietic stem cells and precautions for infusion to patient: Guidelines from the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)]. / Modalités de préparation, cryopréservation, décongélation des cellules souches hématopoïétiques et précautions pour infusion au patient : recommandations de la Société francophone de greffe de moelle et de thérapie cellulaire (SFGM-TC).

To date, despite an existing regulatory framework and standards, there are no true technical recommendations. A survey of 23 cell processing facilities (France, Belgium and Switzerland) has allowed to overview current practices according to cellular products specifications upon arrival at the facility, with modalities for their preparation prior to cryopreservation, storage, thawing and finally for infusion to patient. Data analysis shows great variability of collected volumes and cell concentrations in cellular products. Despite homogeneous practices for handling cells at the facility, methods vary between centers, especially for the choice of cryoprotective solutions and thawing methods. During the workshop, practices have been discussed and summarized to write of recommendations about the following topics: processing and cryopreservation, thawing, bedside precautions (for infusion). This work identifies some improvements in terms of collection, choice of wash solution of thawed cells and validation of the conditions of carriage.

Real life thromboprophylaxis in orthopedic surgery in Italy. Results of the GIOTTO study.

INTRODUCTION: Data from a prospective, multicentre observational study (Studio GIOTTO) were analyzed to determine, in clinical practice, the pattern of VTE prophylaxis and adherence to international guidelines recommendations in major orthopedic surgery (MOS) - including total hip arthroplasty (THA), total knee arthroplasty (TKA) and hip fracture surgery (HFS) - and knee arthroscopic surgery (KAS). METHODS: In 2010, the first consecutive 30 patients hospitalized in Italian centers for MOS and the first 15 for KAS were enrolled and treated according to the usual practice. RESULTS: 2010 patients were admitted for MOS (577 TKA, 787 THA and 646 HFS) and 993 for KAS; mean ± SD age was 71.7 ± 8 and 43.0 ± 15 years, and female prevalence was 65.6% and 31.1% in MOS and KAS, respectively. Most (66.7%; 95% CI: 65-69%) patients admitted for MOS received a combined VTE prophylaxis, consisting of both pharmacological and physical tools, and 33.2% (95% CI: 31-35%) only pharmacological. For KAS figures were 23.7 (95% CI: 21-26%) and 75.3% (95% CI: 72-77%). Most MOS (91%; 95% CI: 89-92%) and KAS (95% CI: 98-100%) patients receiving pharmacological thromboprophylaxis were treated with low molecular weight heparin (LMWH), for (median) 40 days in TKR, 39 days in THR, 44 in HFS, and 16 in KAS. Patients receiving <35 days of LMWH prophylaxis among those undergoing THR and HFS were 8.9% and 5.9%, respectively. CONCLUSION: Although most patients undergoing orthopedic surgery received VTE prophylaxis, a gap between clinical practice and international guideline recommendations was observed. The reduced adherence to guideline recommendations is relevant for certain choices like type and duration of VTE, and physicians' behavior may reflect the changing approach of guidelines in their different editions.

Thromboprophylaxis after major orthopedic surgery: Improving compliance with clinical practice guidelines.

INTRODUCTION: Identifying risk factors and strategies for the prevention of deep venous thromboembolism in major orthopedic surgery has allowed the development of Clinical Practice Guidelines (CPGs). Currently, there is a gap between clinical practice and the implementation of the recommendations of CPGs. The purpose of this paper is to report the impact of the implementation of improvement strategies on adherence to venous thromboembolism (VTE) prophylaxis guidelines. MATERIALS AND METHODS: We defined 3 quality indicators to assess the adequate use of thromboprophylaxis according to CPGs. We obtained a baseline measurement and identified several barriers for adherence. Six improvement strategies to promote adherence to CPGs were designed and applied. A systematic monitoring of these indicators was performed in real time and a description of the data was completed for patients undergoing primary joint replacement of the hip, knee and shoulder, during February 2012 and August 2014. RESULTS: Data from 773 patients were obtained. In the first trimester, the average of adherence was: 98.3% for medical order in the post-operative note, 60.3% for opportune administration and 67% for adherence to therapy at home. In the trimester, the rates of adherence were 100%, 95.7% and 100% respectively. CONCLUSIONS: Combined strategies for improvement of adherence to VTE prophylaxis is associated with higher compliance with clinical practice guidelines.

[Cardiovascular assessment and management prior to non-cardiac surgery. Comment on the new 2014 ESC/ESA guidelines]. / Kardiovaskuläre Beurteilung und Management vor nichtkardialen Eingriffen. Kommentar zur neuen ESC/ESA-Leitlinie 2014.

In 2014 the European Society of Cardiology (ESC) and the European Society of Anaesthesiology (ESA) published an update of the guidelines on "non-cardiac surgery: cardiovascular assessment and management". Epidemiological data underline the relevance of these guidelines: a total of 5.7 million surgical procedures are performed per year in patients with increased cardiac risk and approximately 167,000 cardiac complications occur per year in Europe of which 19,000 are life-threatening. This new version of the guidelines highlights the patient characteristics, such as functional capacity and comorbidities and procedure-specific aspects for perioperative risk stratification. Decision-making for preoperative stress tests and coronary angiography has been simplified, procedure-specific risks have been revised and the role of multidisciplinary teamwork for high risk procedures is emphasized. A standardized stepwise approach on how to stratify patient-specific and procedure-associated risks has been established. For the first time, the guidelines recommend perioperative regimens on dual antiplatelet therapy and the new oral anticoagulants (NOAC).

Venous Thromboembolism Prophylaxis in Orthopaedic Trauma Patients: A Survey of OTA Member Practice Patterns and OTA Expert Panel Recommendations.

OBJECTIVES: First, to provide the readership with a summation of the current practice patterns of North American orthopaedic surgeons for venous thromboembolism prophylaxis after musculoskeletal trauma. Second, to establish a set of guidelines and recommendations based on the most current and best available evidence for venous thromboembolism (VTE) prophylaxis after musculoskeletal trauma. METHODS: A 24 item questionnaire titled "OTA VTE Prophylaxis Survey" was sent to active members of the Orthopaedic Trauma Association. PubMed and OVID/MEDLINE were used to search the current published literature regarding VTE prophylaxis in trauma patients using the following search terms: deep venous thrombosis, DVT, pulmonary embolism, PE, venous thromboembolism, VTE, prophylaxis, trauma, fracture, pneumatic compression device, PCD, sequential compression device, SCD, screening, ultrasound, duplex, ultrasonography, DUS, venography, magnetic resonance venography, MRV, inferior vena cava, IVC, filter, and IVCF. Each recommendation was graded using articles that were considered by the subcommittee as "the best available evidence" using the grading system adopted and endorsed by the American Academy of Orthopedic Surgeons' Evidenced Based Quality and Value committee. RESULTS: Overall, 185 of 1545 members completed the online survey. The range and variety of prophylaxis and screening methods used among orthopaedic trauma surgeons in North America is large, with a number of agents or methods for which no literature exists to support their use in musculoskeletal trauma. A set of recommendations and guidelines were constructed based on the results of the literature analysis and graded according to guidelines mentioned above. CONCLUSIONS: Due to the wide variability in practice patterns, poor scientific support for various therapeutic regimens and important medical-legal implications highlighted by the survey, a standardized set of guidelines and recommendations for VTE prophylaxis after musculoskeletal trauma will be critical in helping to improve patient care and minimize surgeons' exposure to potentially litigious activity. LEVEL OF EVIDENCE: Therapeutic Level V. See Instructions for Authors for a complete description of levels of evidence.

S3 guidelines for the management of anticoagulation in cutaneous surgery.

BACKGROUND: An increasing number of patients are being treated with anticoagulants and platelet inhibitors. Whenever surgical procedures of the skin are required, questions arise regarding the perioperative management of anticoagulation. METHODS: Development of S3 guidelines following the requirements of the Association of Scientific Medical Societies, systematic literature search and analysis, use of GRADE methodology, structured consensus conference using a nominal group process. RESULTS: During cutaneous surgery, treatment with acetylsalicylic acid (ASA) should be continued if medically necessary. In procedures with a higher risk of bleeding and a positive bleeding history, INR should be determined preoperatively. Surgical procedures of the skin with a higher risk of bleeding should not be performed if the INR is above therapeutic range. Bridging from vitamin K antagonists (VKA) to heparin should not be performed just because of the surgery of the skin. As to direct-acting oral anticoagulants, the last dose should be taken 24 h preoperatively. CONCLUSIONS: The recommendations issued by the German guidelines group are mostly in line with recommendations provided by other guidelines. The American ìChest-Guidelineì recommends continuing VKAs and acetylsalicylic acid during minor dermatologic procedures. In their guidelines, the German College of General Practitioners and Family Physicians considers an INR of 2 to be adequate in surgical procedures on the skin.
