Children's surgery and the emergency, critical, and operative care resolution: immediate actions to eliminate disparities in surgical anesthesia and perioperative care for all children.

1.7 billion children lack access to surgical care worldwide. The emergency, critical, and operative care (ECO) resolution represents a call to action to reinvigorate the efforts to address these disparities. We review the ECO resolution and highlight the avenues that may be utilized in advocating for children's surgical care.

Perioperative Management of Massive Anterior Encephalocele in a Newborn: A Case Report.

Anterior encephaloceles are rare neural tube defects posing anesthetic challenges. While anterior encephaloceles can cause airway obstruction at birth, this presentation is very rare and to our knowledge not reported in the literature. This case report describes a 34 weeks +0 days gestation, 2.6 kg, newborn with a massive nasoethmoidal anterior encephalocele creating significant external airway obstruction, necessitating emergent and thoughtful airway management and anesthetic care. Our most important perioperative considerations for this newborn included spontaneous ventilation using awake fiberoptic bronchoscopic intubation with lidocaine airway topicalization, secure endotracheal tube attachment, and avoiding noninvasive positive airway pressure postoperatively to avoid pneumocephalus.

Effects of perioperative application of esketamine on postpartum depression in cesarean section: A systematic review and meta-analysis.

BACKGROUND: To evaluate the effect of perioperative esketamine administration on postpartum depression in pregnant women undergoing cesarean section. METHODS: Data sources was PubMed, Embase, Web of Science, and Cochrane Library from inception to February 1, 2024. Randomized controlled trials in pregnant women undergoing cesarean section were selected and compared to the use of esketamine in the perioperative period. The primary outcome measure was the incidence of postpartum maternal depression. Preferred reporting items for systematic reviews and meta-analyses were used. Data pooled by random-effects models are presented as risk ratios (RR) (95% confidence intervals, 95% CI) or mean differences (95% CI). This review was registered in PROSPERO (ID: CRD42023431197). RESULTS: We included 8 studies with a total of 1655 participants. The quality of the studies was rated high or unclear. Seven studies involving 1485 participants reported the incidence of postpartum depression. Compared with pregnant women undergoing cesarean section without the use of esketamine, those using esketamine in the perioperative period showed a 48% decreased risk of developing postpartum depression (RR: 0.52, 95% CI: 0.35-0.79) and a 1.43-point reduction in EPDS (Edinburgh Postnatal Depression Scale) (mean difference: -1.43, 95% CI: -2.32 to -0.54). For immediate intraoperative adverse reactions, the application of esketamine caused maternal nausea and vomiting (RR: 2.16, 95% CI: 1.22-3.81), dizziness (RR: 6.11, 95% CI: 1.49-24.98), and hallucinations (RR: 6.83, 95% CI: 1.57-29.68) compared to no esketamine use. CONCLUSIONS: Perioperative use of esketamine in pregnant women undergoing cesarean section may reduce postpartum depression and increase intraoperative adverse reactions, but has no significant effect on postoperative adverse reactions.

Surgical Site Infections After Pediatric Liver Transplantation-Impact of a Change in Perioperative Prophylactic Antibiotic Protocol.

BACKGROUND: In spite of improved survival rates after pediatric liver transplantation, infections remain major contributors to perioperative morbidity and mortality. This study aimed to understand the impact of type and duration of perioperative antibiotic prophylaxis (PAP) on the occurrence of surgical site infections (SSIs). METHODS: In total, 125 patients who underwent liver transplantation between 2014 and 2020 were retrospectively included. Patients were categorized into two periods based on changes in the standard PAP regimen. Risk factors for SSIs were investigated, including the influence of PAP duration, antibiotic substances used, and abdominal patch placement using multivariable regression models. RESULTS: SSIs occurred in 23 (19%) of 119 analyzed patients and were not impacted by changes in the PAP regimen. The placement of an abdominal patch was a relevant risk factor for SSIs (odds ratio 3.81; 95% confidence interval [CI] 1.15-12.68). Longer PAP duration reduced the occurrence of SSIs by up to 4.6 percentage points (95% CI 0.0-9.1) per day, with its effect diminishing with longer duration. The choice of antibiotic substances for PAP changed after implementation of the new protocol, with a decline in vancomycin usage from 14% to 3%. CONCLUSION: The results of this study emphasize the need for evidence-based PAP regimens tailored to the unique needs of pediatric liver transplant recipients. The occurrence of SSIs remains complex and is influenced by various factors beyond the PAP regimen. Multicentric efforts to develop effective prevention strategies against SSIs in this vulnerable population are warranted.

Role of Multimodal Monitoring in the Management of Massive Blood Transfusion in Pediatric Patients Undergoing Excision of Choroid Plexus Carcinoma - A Case-Based Review of a Novel Perioperative Protocol.

Choroid plexus carcinomas (CPCs) are rare intraventricular lesions encountered in the pediatric population. The dreaded perioperative complication causing high mortality and morbidity in patients undergoing excision of CPC is massive intraoperative hemorrhage, which results in massive blood transfusion, and coagulopathy. Hence, the main crux of perioperative management is to tackle intraoperative hemorrhage and coagulopathy by instituting goal-directed blood transfusion guided by multimodality monitoring. This case series and literature review aims to present our institutional experience wherein the patients had a favorable outcome post-excision of CPC owing to goal-directed blood transfusion protocol guided by multimodality monitoring in the perioperative period.

Perioperative Naltrexone Management: A Scoping Review by the Perioperative Pain and Addiction Interdisciplinary Network.

Substance use disorders, including alcohol use disorder, are a public health concern that affect more than 150 million people globally. The opioid antagonist naltrexone is being increasingly prescribed to treat opioid use disorder, alcohol use disorder, and chronic pain. Perioperative management of patients on naltrexone is inconsistent and remains a controversial topic, with mismanagement posing a significant risk to the long-term health of these patients. This scoping review was conducted to identify human studies in which the perioperative management of naltrexone was described. This review includes a systematic literature search involving Medline, Medline In-Process, Embase, PsycINFO, and Web of Science. Seventeen articles that describe perioperative naltrexone management strategies were included, including thirteen guidelines, one case report, and three randomized trials. Despite its use in patients with alcohol use disorder and chronic pain, no clinical studies, case reports, or guidelines addressed naltrexone use in these clinical populations. All of the guideline documents recommended the preoperative cessation of naltrexone, irrespective of dose, indication, or route of administration. None of these guideline documents were designed on the basis of a systematic literature search or a Delphi protocol. As described by the primary studies, perioperative pain relief varied depending on naltrexone dose and route of administration, time since last naltrexone administration, and underlying substance use disorder. None of the studies commented on the maintenance of recovery for the patient's substance use disorder in the context of perioperative naltrexone management. The current understanding of the risks and benefits of continuing or stopping naltrexone perioperatively is limited by a lack of high-quality evidence. In patients with risk factors for return to use of opioids or alcohol, the discontinuation of naltrexone should have a strong rationale. Future studies and guidelines should seek to address both acute pain management and maintaining recovery when discussing perioperative naltrexone management strategies.

Management of Extracorporeal Membrane Oxygenation Anticoagulation in the Perioperative Period: The Pediatric Extracorporeal Membrane Oxygenation Anticoagulation CollaborativE Consensus Conference.

OBJECTIVES: To derive systematic review-informed, modified Delphi consensus regarding the management of children on extracorporeal membrane oxygenation (ECMO) undergoing invasive procedures or interventions developed by the Pediatric Anticoagulation on ECMO CollaborativE (PEACE) Consensus Conference. DATA SOURCES: A structured literature search was performed using PubMed, EMBASE, and Cochrane Library (CENTRAL) databases from January 1988 to May 2021. STUDY SELECTION: ECMO anticoagulation and hemostasis management in the perioperative period and during procedures. DATA EXTRACTION: Two authors reviewed all citations independently, with a third independent reviewer resolving any conflicts. Seventeen references were used for data extraction and informed recommendations. Evidence tables were constructed using a standardized data extraction form. DATA SYNTHESIS: Risk of bias was assessed using the Quality in Prognosis Studies tool. The evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation system. Forty-eight experts met over 2 years to develop evidence-based recommendations and, when evidence was lacking, expert-based consensus statements for the management of bleeding and thrombotic complications in pediatric ECMO patients. A web-based modified Delphi process was used to build consensus via the Research And Development/University of California Appropriateness Method. Consensus was defined as greater than 80% agreement. Four good practice statements, 7 recommendations, and 18 consensus statements are presented. CONCLUSIONS: Although agreement among experts was strong, important future research is required in this population for evidence-informed recommendations.

Effectiveness of Erector Spinae Plane Block as Perioperative Analgesia in Midline Sternotomies: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: With the advancements in regional anesthesia and ultrasound techniques, the use of non-neuraxial blocks like the erector spinae plane block (ESPB) has been increasing in cardiac surgeries with promising outcomes. A total of 3,264 articles were identified through a literature search. Intervention was defined as ESPB. Comparators were no regional technique performed or sham blocks. Four studies with a total of 226 patients were included. Postoperative opioid consumption was lower in the group that received ESPB than the group that did not (weighted mean difference [WMD]: -204.08; 95% CI: -239.98 to -168.19; P < 0.00001). Intraoperative opioid consumption did not differ between the two groups (WMD: -398.14; 95% CI: -812.17 to 15.98; P = 0.06). Pain scores at 0 hours were lower in the group that received ESPB than the group that did not (WMD: -1.27; 95% CI: -1.99 to -0.56; P = 0.0005). Pain scores did not differ between the two groups at 4-6 hours (WMD: -0.79; 95% CI: -1.70 to 0.13; P = 0.09) and 12 hours (WMD: -0.83; 95% CI: -1.82 to 0.16; P = 0.10). Duration of mechanical ventilation in minutes was lower in the group that received ESPB than the group that did not (WMD: -45.12; 95% CI: -68.82 to -21.43; P = 0.0002). Given the limited number of studies and the substantial heterogeneity of measured outcomes and interventions, further studies are required to assess the benefit of ESPB in midline sternotomies.

Effects of Dexmedetomidine on Perioperative Glycemic Control in Adult Diabetic Patients Undergoing Cardiac Surgery.

BACKGROUND AND OBJECTIVE: To study the effects of dexmedetomidine (DEX) on perioperative blood glucose levels in adult diabetes mellitus (DM) patients undergoing cardiac surgery. METHODS AND MATERIAL: A prospective, observational study was conducted on 100 adult diabetic patients aged between 18 and 75 years undergoing cardiac surgery with cardiopulmonary bypass (CPB). The patients were divided into two groups (group D and group C) of 50 each. Group D patients received DEX infusion, whereas the group C patients received 0.9% normal saline infusion. RESULTS: The blood glucose levels, heart rate, mean arterial pressure, and serum potassium levels at different time points were comparable between the two groups (P > 0.05). The mean dose of insulin required in the combined population as well as in both controlled and uncontrolled DM patients was significantly less in group D than in group C (combined population - 36.03 ± 22.71 vs 47.82 ± 30.19 IU, P = 0.0297; uncontrolled DM - 37.36 ± 23.9 IU vs 48.16 ± 25.15 IU, P = 0.0301; controlled DM - 34.7 ± 21.5 IU vs 47.63 ± 35.25 IU, P = 0.0291). Duration of mechanical ventilation and VIS were comparable between the two groups. The incidence of arrhythmias (20% vs 46%, P = 0.0059) and delirium (6% vs 20%, P = 0.0384) was significantly less in group D than in group C. None of the patients in either group had stroke, myocardial ischemia, and mortality. CONCLUSION: The results suggested that DEX infusion during the intraoperative period was very effective for perioperative glycemic control and reduction of insulin requirement in DM patients undergoing cardiac surgery.

Novel Peri-Operative Strategy for Sickle Cell Disease with Tetralogy of Fallot.

ABSTRACT: Peri-operative management of cyanotic congenital heart disease in a patient of sickle cell disease (SCD) can be challenging. We report a case of Tetralogy of Fallot and homozygous SCD with history of multiple blood transfusions and sickle cell crises who underwent intracardiac repair. Hemoglobin S level was reduced from 75% pre-operative to 21.8% postoperative with a combination of pre-operative blood transfusion, intraoperative exchange transfusion, and normothermic cardiopulmonary bypass (CPB). Pre-operative optimization and safe intraoperative conduct were essential to avoid sickling crises.

Perioperative Management of an Obstetric Patient with Eisenmenger Syndrome and Pre-Eclampsia Using Milrinone.

ABSTRACT: Pregnancy in a patient with pulmonary hypertension carries a high risk of mortality. It poses multiple problems in the management of pregnancy, labor, and postpartum, thereby emphasizing the need for a multidisciplinary team for a successful outcome. We describe the successful management of a case of Eisenmenger syndrome who developed pre-eclampsia during her 28 weeks of pregnancy. As far as our knowledge, this is the first case report that describes the use of milrinone in a parturient for a successful outcome.

Usefulness of Perioperative Nutritional Therapy with the Glutamine/Arginine/Calcium ß-Hydroxy-ß-Methylbutyrate Product in Esophageal Cancer Surgery: A Single-Center Retrospective Study.

A useful perioperative nutritional therapy for highly invasive esophageal cancer surgical cases needs to be developed. We clarified the usefulness of amino-acid-enriched nutritional therapy using glutamine (Gln)/arginine (Arg)/calcium ß-hydroxy-ß-methylbutyrate (HMB) products on the short-term postoperative outcomes of minimally invasive esophagectomy for esophageal cancer. Altogether, 114 patients (Gln/Arg/HMB group) received perioperative nutritional therapy with Gln/Arg/HMB products, and we retrospectively investigated the change in nutritional parameters including skeletal muscle mass, occurrence of postoperative complications, and short-term postoperative outcomes in this group. The results were compared between the Gln/Arg/HMB and control groups (79 patients not receiving the Gln/Arg/HMB products). The incidence of all postoperative complications, sputum expectoration disorder, and pleural effusion of grade ≥ III was significantly lower in the Gln/Arg/HMB group (62.0% vs. 38.6%, p = 0.001; 44.3% vs. 28.1%, p = 0.020; 27.8% vs. 13.2%, p = 0.011, respectively). The psoas muscle area and postoperative body weight were significantly higher at 1 month and 1 year after surgery in the Gln/Arg/HMB group than in the control group (93.5% vs. 99.9%, p < 0.001; 92.0% vs. 95.4%, p = 0.006). Perioperative amino-acid-enriched nutritional therapy may improve the short-term postoperative outcomes, nutritional status, and skeletal muscle mass of esophageal cancer surgical patients.

Perioperative Care of the Patient with Directives Limiting Life-Sustaining Treatments.

Like most complex aspects of procedural care, sound perioperative management of limits to life-sustaining medical therapy requires a multidisciplinary team-based approach bolstered by appropriate care management strategies. This article discusses the implications of care for the patient for whom limitations of life-sustaining care are in place and the roles and responsibilities of each provider in supporting quality procedural care compatible with patients' right to self-determination. The authors focus on the roles of the surgeon, preoperative clinic provider, anesthesiologist, and postoperative care consultants and discuss how the health care system and care pathways can support and improve adherence to best practices.

The role of Advance Directives and Living Wills in Anesthesia Practice.

Preoperative review of existing advance directives and a discussion of patient goals should be routinely done to address any potential limitations on resuscitative therapies during perioperative care. Both surgeons and anesthesiologists should be collaboratively involved in these discussions, and all perioperative physicians should receive training in shared decision making and goals of care discussions. These discussions should center around patient preferences for limitations on life-sustaining medical therapy, which should be accurately documented and adhered to during the perioperative period. Patients should be informed that limitations of life-sustaining medical therapy may increase their risk of postoperative mortality.

Incidence of Fatigue Following Dexamethasone Administration for Supportive Therapy and Efficacy of Tapering in Perioperative Chemotherapy for Breast Cancer: A Retrospective Observational Study.

In perioperative chemotherapy for breast cancer, dexamethasone (DEX) is administered at high dose to prevent adverse effects. Abrupt cessation of high-dose DEX treatment induces fatigue, but the incidence of the fatigue is uncertain. In this study, we retrospectively evaluated the incidence of fatigue following DEX administration for supportive therapy and the improvement of fatigue with DEX tapering, a gradual reduction of the daily dose, in breast cancer patients. The subjects were 124 patients with breast cancer receiving epirubicin- or docetaxel-based regimens as perioperative chemotherapy. Of all patients, 16.1% of patients experienced fatigue after cessation of DEX administration. The severity of fatigue was grade 1 in 6.5% of patients, grade 2 in 8.1% of patients, and grade 3 in 1.6% of patients. There were no significant differences in dose and duration of DEX administration between the group with fatigue and the group without fatigue. In almost all patients with fatigue, DEX tapering was performed from the next cycle. The efficacy of DEX tapering was evaluated by comparing the grade and subjective symptoms. Following DEX tapering, the severity of fatigue was significantly reduced (p < 0.05), and the subjective symptom was improved in 94.7% of patients. Therefore, fatigue is occasionally induced after the cessation of DEX administration for supportive therapy in breast cancer patients. The tapering of DEX may be effective for fatigue.

Incompatibility of the short-acting benzodiazepine remimazolam with common perioperative medication.

BACKGROUND: Remimazolam is a relatively new benzodiazepine with growing use in procedural sedation and general anaesthesia. Initiated by case reports, the physical incompatibility of remimazolam with ringer's acetated and ringer's lactated solution has been reported. More recently, remifentanil, fentanyl, rocuronium, vecuronium, dexmedetomidine, and midazolam, have been investigated and suggested safe for coadministration with remimazolam. Apart from case reports, incompatibility for other frequently used drugs remains unknown. METHODS: Sixty-five drugs and intravenous fluids were tested for possible precipitation with remimazolam in a simulated y-site administration. Equal volumes of the test drug were injected into the remimazolam solution, examined and photo documented at 1, 15, 30 and 60 min after mixture. Examination was taken by two independent investigators. pH was measured before, and 60 min after mixing the drugs. RESULTS: Seventeen (26.15%) drugs or fluids showed precipitation, 47 (72.31%) did not show any sign of interaction. Propofol could not be assessed, because of the turbidity of the substance itself. Precipitation occurred immediately and remained stable in all timestamps. The incompatible drug-remimazolam-mixtures had a median pH of 7.15 (6.67, 8.01), the non-precipitating mixtures a median pH of 4.75 (3.8, 5.6). The pH-values of both groups were significantly different (Mann-Whitney-U-test; p < .00001). There is an increasing risk for precipitation with more basic baseline pH-levels of the tested drug. No interaction was seen in baseline pH below 5. CONCLUSIONS: Remimazolam (Byfavo®) is incompatible with ampicillin/ sulbactam, calcium gluconate, clindamycin, dexamethasone, dimenhydrinate, an 148mval/l electrolyte - glucose 1% solution (E148G1®), furosemide, a 4% gelatine volume expander (gelafundin®), heparin sodium, insulin, meropenem, sodium bicarbonate 8.4%, prednisolone, the crystalloid infusions jonosteril® and sterofundin®, thiopental and tranexamic acid. The results strongly affirm remimazolam's safety requirements: A separate line for remimazolam and an approved compatible baseline infusion is mandatory and an alternative way to administer bolus medication is required.

Perioperative Glutamine Supplementation May Restore Atrophy of Psoas Muscles in Gastric Adenocarcinoma Patients Undergoing Gastrectomy.

BACKGROUND: Sarcopenia, characterized by degenerative skeletal muscle loss, is increasingly linked to poor surgical outcomes. Glutamine, an immune-modulating formula, may stimulate muscle protein synthesis and inhibit degradation. We used the psoas major muscle area (PMMA) at the third lumbar vertebra, normalized for height (PMMA index), as a skeletal muscle indicator. This study investigates whether perioperative glutamine supplementation mitigates psoas muscle atrophy. METHODS: We enrolled gastric adenocarcinoma (GA) patients undergoing gastrectomy. Computed tomography assessed the psoas muscle short axis. Muscle atrophy was estimated by changes between preoperative and three-month post-gastrectomy scans. Perioperative glutamine supplementation (PGS) comprised five-day parenteral plus one-month oral use. Propensity score matching minimized potential bias. A linear regression model predicted the association. RESULTS: Of 516 patients analyzed (2016-2019), 100 (19.4%) received PGS. After propensity score matching, each group contained 97 cases. The PGS group showed a significantly higher median PMMA index change than the non-PGS group (0.3 vs. -0.3 cm2/m2, p = 0.004). Multivariate analysis revealed that PGS was significantly associated with increased PMMA index (coefficient = 0.60; 95% CI: 0.19-1.01; p = 0.005). CONCLUSIONS: PGS may help restore psoas muscle atrophy in GA patients undergoing gastrectomy. The underlying mechanisms likely relate to glutamine's role in protein metabolism and immune function. Further studies are needed to elucidate these mechanisms fully.

Perioperative management of a patient with systemic lupus erythematosus-associated antiphospholipid syndrome undergoing mandibular third molar surgery.

Antiphospholipid syndrome (APS) is a systemic autoimmune condition characterised by recurrent venous or arterial thrombosis and pregnancy complications, with persistent antiphospholipid autoantibodies. APS is often found in conjunction with other autoimmune diseases, such as systemic lupus erythematosus (SLE). SLE-associated APS patients may require dental procedures like tooth extractions. Due to the complex nature of this autoimmune disorder, perioperative management requires a comprehensive approach involving various medical specialists.These patients are frequently taking medications like anticoagulants, antiplatelet drugs, disease-modifying drugs and immunosuppressants. This medication regimen can increase their risk of postoperative complications, including bleeding, thrombosis, delayed healing and postoperative infections. Currently, there are no established guidelines for performing tooth extractions in individuals with SLE-associated APS.We report a case of SLE-associated APS with pericoronitis requiring surgical extraction. The purpose of this report is to offer practical recommendations for the perioperative management of dental procedures and alteration in medications used in such cases.
