Vomiting after intrathecal chemotherapy under anesthesia in pediatric patients with hematologic cancers: A cohort study. Paediatr Anaesth 2024; 34:51-59. [PMID: 37727104 DOI: 10.1111/pan.14756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 08/22/2023] [Accepted: 08/28/2023] [Indexed: 09/21/2023]
Abstract
INTRODUCTION Despite preventive strategies, vomiting is an adverse event affecting patients with cancer. However, literature on the incidence and risk factors for vomiting in pediatric patients with cancer are scarce. AIM To assess the incidence and risk factors for vomiting within 24 h and goodness of fit for the Eberhart score in pediatric patients with hematologic cancers after receiving intrathecal chemotherapy under deep sedation. METHODS This prospective cohort study included patients under 20 years of age with hematologic cancers who were scheduled to undergo intrathecal chemotherapy under anesthesia. The primary outcome was the occurrence of vomiting within 24 h after the end of anesthesia. Sociodemographic and procedure data and underlying diseases were collected. Patients were monitored during the procedure, in the postanesthesia care unit, and the day after (by phone call). RESULTS A total of 139 patients were included, and the incidence of vomiting was 30.9% within 24 h after intrathecal chemotherapy under anesthesia, with 90.7% of vomiting prior to 6 h. Prophylactic ondansetron was administered prior to the procedure to 45.3% of patients. Risk factors for vomiting were female gender (hazard ratio: 2.47, 95% confidence interval: 1.35-4.53, p: .003), consolidation phase of treatment (hazard ratio: 2.16, 95% confidence interval: 1.10-4.24, p: .025), and history of kinetosis (hazard ratio: 2.49, 95% confidence interval: 1.31-4.70, p: .005). Incidence of vomit was higher than estimated by the Eberhart score distribution (observed incidence in patients with a score of zero: 33.3%; with a score of one: 28.8%; with a score of two: 60%). CONCLUSION A high incidence of vomiting was observed within 24 h after intrathecal chemotherapy under propofol deep sedation. Risk factors for this outcome were established (being female, consolidation phase of treatment, and previous kinetosis), and evidence suggested that the Eberhart score was not suitable for the studied population.

Abstract
Difficult airway management in pediatrics during anesthesia represents a major challenge, requiring a careful approach, advanced technical expertise, and accurate protocols. The task force of the Brazilian Society of Anesthesiology (SBA) presents a report containing updated recommendations for the management of difficult airways in children and neonates. These recommendations have been developed based on the consensus of a panel of experts, with the objective of offering strategies to overcome challenges during airway management in pediatric patients. Grounded in evidence published in international guidelines and expert opinions, the report highlights crucial steps for the appropriate management of difficult airways in pediatrics, encompassing assessment, preparation, positioning, pre-oxygenation, minimizing trauma, and, paramountly, the maintenance of arterial oxygenation. The report also delves into additional strategies involving the use of advanced tools, such as video laryngoscopy, flexible intubating bronchoscopy, and supraglottic devices. Emphasis is placed on the simplicity of implementing the outlined recommendations, with a focus on the significance of continuous education, training through realistic simulations, and familiarity with the latest available technologies. These practices are deemed essential to ensure procedural safety and contribute to the enhancement of anesthesia outcomes in pediatrics.

Abstract
This second joint document, written by experts from the Brazilian Association of Allergy and Immunology (ASBAI) and Brazilian Society of Anesthesiology (SBA) concerned with perioperative anaphylaxis, aims to review the pathophysiological reaction mechanisms, triggering agents (in adults and children), and the approach for diagnosis during and after an episode of anaphylaxis. As anaphylaxis assessment is extensive, the identification of medications, antiseptics and other substances used at each setting, the comprehensive data documentation, and the use of standardized nomenclature are key points for obtaining more consistent epidemiological information on perioperative anaphylaxis.

Abstract
Background and objectives Conjoined twins are monozygotic twins physically joined at some part of the body. This is a rare phenomenon, estimated between 1:50,000 and 1:200,000 births. The objective of this report is to present the anesthetic management and the perioperative challenges for a separation surgery. Case report Thoraco-omphalopagus twins were diagnosed by ultrasound and were followed by the fetal medicine team of the service. After 11 h of cesarean surgery, the pediatric surgical team chose to separate the twins. They were monitored with cardioscopy, oximetry, capnography, nasopharyngeal thermometer, urinary output, and non-invasive blood pressure. We chose inhaled induction with oxygen and 4% Sevoflurane. T1 patient was intubated with a 3.5 uncuffed endotracheal tube, and, after three unsuccessful intubation attempts of patient T2, a number 1 laryngeal mask was used. After securing the twins’ airway, the induction was supplemented with fentanyl, propofol, and rocuronium. Mechanical ventilation in controlled pressure mode (6 mL.kg−1) and lumbar epidural (L1–L2) with 0.2% ropivacaine (2.5 mg.kg−1) were used. The pediatric surgical team initiated the separation of the twins via sternotomy, ligation of hepatic vessels. After 2 hours of procedure, the separation was completed, continuing the surgical treatment of T1 and the support of T2 until his death. Conclusions Conjoined twin separation surgery is a challenge, which requires planning and coordination of a multidisciplinary team during all stages.

Abstract
Introduction: Successful renal transplant and consequent good graft function depend on a
good surgical technique, an anesthetic that ensures the hemodynamic
stability of the receiver, and appropriate conditions of graft and
recipient. Several factors can interfere with the perfusion of the graft and
compromise its viability. The objective of this study was to evaluate
perioperative factors associated with delayed graft function (DGF) in renal
transplantation patients. Methods: This is a historical cohort study of patients who underwent renal
transplantation between 2011 and 2013. Three hundred and ten transplants
were analyzed. DGF was defined as the need for dialysis during the first
week post-transplant. Logistic regression with a stepwise technique was used
to build statistical models. Results: Multivariate analysis revealed the following risk factor for DGF: combined
anesthesia technique (OR = 3.81, 95%CI, 1.71 to 9.19), a fluid regimen <
50 mL·kg-1 (OR = 3.71, 95%CI, 1.68 to 8.61), dialysis for more
than 60 months (OR = 4.77, 95%CI, 1.93 to 12.80), basiliximab (OR = 3.34,
95%CI, 1.14 to 10.48), cold ischemia time > 12 hour (OR = 5.26, 95%CI,
2.62 to 11.31), living donor (OR = 0.19, 95%CI, 0.02 to 0.65), and early
diuresis (OR = 0.02, 95%CI, 0.008 to 0.059). The accuracy of this model was
92.6%, calculated using the area under the ROC curve. The incidence of DGF
in the study population was 76.1%. Conclusions: Combined anesthesia technique, dialysis for more than 60 months, basiliximab,
and cold ischemia time > 12 hours are risk factor for DGF, while liberal
fluid regimens and kidneys from living donors are protective factors.

Abstract
Introduction Since anesthesia complications associated with unexpected difficult airway are potentially catastrophic, they should be avoided. The modified Mallampati test and jaw-thrust maneuver enable the identification of difficult airway. The aim of this study was to associate the modified Mallampati test and the jaw-thrust maneuver with laryngoscopy (Cormack–Lehane) in an attempt to identify a better predictor of difficult airway in an adult population undergoing elective surgery. Method A cross-sectional study in which 133 adult patients undergoing elective surgery requiring tracheal intubation were analyzed. The accuracy and specificity of the modified Mallampati test and jaw-thrust maneuver were assessed by correlating them with difficult laryngoscopy (Cormack–Lehane Degrees 3 and 4). Results In the 133 patients evaluated the difficult intubation rate found was 0.8%; there was association between the two predictive tests proposed (p = 0.012). The values of 94.5% for specificity and 95.4% for accuracy were found for the jaw-thrust maneuver and for the modified Mallampati test, the values found were 81.1% and 81.2%, respectively. Kappa agreement identified a result of 0.240 between jaw-thrust maneuver and Cormack–Lehane, which was considered reasonable. On the other hand, a poor agreement (κ = 0.06) was seen between modified Mallampati test and Cormack–Lehane test. Conclusion The jaw-thrust maneuver presented superior accuracy and agreement than the modified Mallampati test, showing the ability to identify a difficult airway. It is necessary to emphasize the association of tests in the evaluation of patients, emphasizing their complementarity to minimize the negative consequences of repeated laryngoscopies.

Abstract
INTRODUCTION Blood is an important resource in several lifesaving interventions, such as anemia correction and improvement of oxygen transport capacity. Despite advances, packed red blood cell (PRBC) transfusion still involves risks. The aim of this study was to describe the knowledge of anesthesiologists about the indications, adverse effects, and alternatives to red blood cell transfusion intraoperatively. METHOD Cross-sectional study using a questionnaire containing multiple choice questions and clinical cases related to relevant factors on the decision whether to perform PRBC transfusion, its adverse effects, hemoglobin triggers, preventive measures, and blood conservation strategies. The questionnaire was filled without the presence of the investigator. Likert scale was used and the average rank of responses was calculated. The Epi Info 7 software was used for data analysis. RESULTS 79% of the institution's anesthesiologists answered the questionnaire; 100% identified the main adverse effects related to blood transfusion. When asked about the factors that influence the transfusion decision, hemoglobin level had the highest agreement (MR=4.46) followed by heart disease (MR=4.26); hematocrit (MR=4.34); age (RM=4.1) and microcirculation evaluation (MR=4.22). Respondents (82.3%) identified levels of Hb=6g.dL-1 as a trigger to transfuse healthy patient. Regarding blood conservation strategies, hypervolemic hemodilution (MR=2.81) and decided by drugs (MR=2.95) were the least reported. CONCLUSION We identify a good understanding of anesthesiologists about PRBC transfusion; however, there is a need for refresher courses on the subject.

Abstract
PURPOSE: To evaluate the effects of dobutamine (DB), noradrenaline (NA), and their combination (NADB), on volume retention in rabbits submitted to hemorrhage. METHODS: Thirty six rabbits were randomly divided into 6 groups: SHAM, Control, Saline, DB, NA, DB+NA. All the animals, except for SHAM, were subjected to hemorrhage of 25% of the calculated blood volume. Control animals were replaced with their own blood. The other groups received NSS 3 times the volume withdrawn. The intravascular retention, hematocrit, diuresis, central venous pressure, mean arterial pressure, NGAL, dry-to-wet lung weight ratio (DTWR) and the lung and kidney histology were analyzed. RESULTS: Replacement with NSS and NA, DB or NA+DB did not produce differences in the intravascular retention. After hemorrhage, the animals presented a significant decrease in the MAP and CVP, which were maintained until volume replacement. Regarding NGAL, dry-to-wet-lung-weight ratio, lung and kidney histology, there were no statistical differences between the groups. CONCLUSION: The use of noradrenaline, dobutamine or their combination did not increase the intravascular retention of volume after normal saline infusion.

Abstract
BACKGROUND AND OBJECTIVE Postoperative pain treatment in mastectomy remains a major challenge despite the multimodal approach. The aim of this study was to investigate the analgesic effect of intravenous lidocaine in patients undergoing mastectomy, as well as the postoperative consumption of opioids. METHODS After approval by the Human Research Ethics Committee of the Instituto de Medicina Integral Prof. Fernando Figueira in Recife, Pernambuco, a randomized, blind, controlled trial was conducted with intravenous lidocaine at a dose of 3mg/kg infused over 1h in 45 women undergoing mastectomy under general anesthesia. One patient from placebo group was. RESULTS Groups were similar in age, body mass index, type of surgery, and postoperative need for opioids. Two of 22 patients in lidocaine group and three of 22 patients in placebo group requested opioid (p=0.50). Pain on awakening was identified in 4/22 of lidocaine group and 5/22 of placebo group (p=0.50); in the post-anesthetic recovery room in 14/22 and 12/22 (p=0.37) of lidocaine and placebo groups, respectively. Pain evaluation 24h after surgery showed that 2/22 and 3/22 patients (p=0.50) of lidocaine and placebo groups, respectively, complained of pain. CONCLUSION Intravenous lidocaine at a dose of 3mg/kg administered over a period of an hour during mastectomy did not promote additional analgesia compared to placebo in the first 24h, and has not decreased opioid consumption. However, a beneficial effect of intravenous lidocaine in selected and/or other therapeutic regimens patients cannot be ruled out.

Abstract
BACKGROUND AND OBJECTIVES Vaginal birth delivery may result in acute and persistent perineal pain postpartum. This study evaluated the association between catastrophizing, a phenomenon of poor psychological adjustment to pain leading the individual to magnify the painful experience making it more intense, and the incidence and severity of perineal pain and its relationship to perineal trauma. METHOD Cohort study conducted with pregnant women in labor. We used the pain catastrophizing scale during hospitalization and assessed the degree of perineal lesion and pain severity in the fi rst 24 hours and after 8 weeks of delivery using a numerical pain scale. RESULTS We evaluated 55 women, with acute pain reported by 69.1%, moderate/severe pain by 36.3%, and persistent pain by 14.5%. Catastrophizing mean score was 2.15 } 1.24. Catastrophizing patients showed a 2.90 relative risk (RR) for perineal pain (95% CI: 1.08-7.75) and RR: 1.31 for developing persistent perineal pain (95% CI: 1.05-1.64). They also showed a RR: 2.2 for developing acute and severe perineal pain (95% CI: 1.11-4.33). CONCLUSIONS The incidence of acute and persistent perineal pain after vaginal delivery is high. Catastrophizing pregnant women are at increased risk for developing acute and persistent perineal pain, as well as severe pain. Perineal trauma increased the risk of persistent perineal pain.

[PMID: 20863929 DOI: 10.1016/s0034-7094(10)70060-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2009] [Accepted: 05/03/2010] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Spinal anesthesia is used for relief of pain during labor and it is associated with low indices of complications. Studies with levorotatory enantiomers of local anesthetics demonstrate higher safety due to the lower cardiotoxicity. The objective of this study was to evaluate the latency and duration of analgesia and maternal and fetal repercussions with bupivacaine (S75-R25) and ropivacaine in spinal anesthesia for labor analgesia. METHODS A prospective, double-blind, randomized clinical assay was undertaken with 49 labouring parturients with low risk, with indication of vaginal delivery, ages 15 to 35 years, ASA I or II, divided into two groups: GI - 0.25% bupivacaine (S75-R25); GII - 0.20% ropivacaine. RESULTS A statistically significant difference was observed between the two groups 30 minutes after the spinal anesthesia, and pain scores were higher in the ropivacaine group. Statistically significant differences were not observed regarding the latency of analgesia, sensorial level of the blockade, volume of local anesthetic, rescue dose, duration of labor and analgesia, frequency of instrument-assisted labor, hemodynamic changes, Apgar scores or umbilical cord blood pH, and incidence of adverse events. CONCLUSIONS The use of bupivacaine (S75-R25) and ropivacaine in labor analgesia provided good conditions for spinal anesthesia with small indices of adverse events.

Abstract
BACKGROUND AND OBJECTIVES Postoperative pain is frequent despite of the therapeutic armamentarium available. Its development is related with factors inherent to the surgery and patient. The objective of this study was to evaluate the prevalence of postoperative pain in hospitalized patients and its association with gender and type of surgery. METHODS This is a transversal study in which interviews were done with 187 patients undergoing surgeries. The incidence of pain in the first 24 hours and its severity according to a numeric rating scale: mild (1 to 3), moderate (4 to 6), and severe (7 to 10), were evaluated. RESULTS Three of 190 patients interviewed were excluded due to difficulties understanding the method used to evaluate the level of pain. In the study population, 66.8% (n = 125) were females; mean age 45.83 +/- 16.17 years, but 25.1% (n = 47) were 60 years old or more. In the first 24 hours, 46% (n = 85) of the patients reported pain. Among male patients, 48.4% (n = 30) complained of pain, while 66.8% (n = 55) of the females did so. The prevalence of pain showed no differences regarding gender (p = 0.536) and age (p = 0.465). As for pain severity, 29.4% of the patients referred mild pain, it was moderate in 43.5%, and severe in 27.1%. A significant association between the incidence of postoperative pain and type of surgery was observed (p = 0.003). CONCLUSIONS This study demonstrated that an elevated number of patients experience pain in the first 24 hours after the surgery. The incidence of pain was higher in patients undergoing general surgery.

Abstract
BACKGROUND AND OBJECTIVES Continuous epidural block is used for relief of labor pain and it is associated with a low incidence of complications. Studies with the levorotatory isomer of local anesthetics demonstrated that they are safer regarding the cardiotoxicity. The objective of this study was to compare analgesia and motor blockade of 0.125% bupivacaine (S50-R50) and 0.125% and 0.25% 50% enantiomeric excess bupivacaine (S75-R25) in continuous epidural block for labor analgesia. METHODS Seventy-five patients in labor participated in this randomized, double-blind study after signing an informed consent. Patients were divided in three groups: GI - 0.125% bupivacaine (S50-R50); GII - 0.125% bupivacaine (S75-R25) and GIII - 0.25% bupivacaine (S75-R25). RESULTS The latency of analgesia, levels of sensorial blockade, volume of local anesthetic, duration of labor and analgesia, frequency of instrumental delivery, Apgar scores, or pH of umbilical cord blood showed no statistically significant differences. The length of time until the first rescue dose was greater and pain scores at 45 minutes were also greater in the 0.25% bupivacaine (S75-R25) group. The intensity of the motor blockade was greater in the 0.125% bupivacaine (S50-R50) group. CONCLUSIONS The motor blockade was less intense with bupivacaine (S75-R25) regardless the concentration, resulting in analgesia of better quality without interfering with the evolution of labor or the vitality of newborns.

Abstract
Alpha1-antitrypsin (AAT) is the main protease inhibitor in human plasma. There are more than 75 variants of this protein that differ from each other by their isoelectric point. Most of these alleles cause a reduction in AAT levels; the most common allele is Pi*Z. The main complications related to the Pi*Z allele are obstructive pulmonary disease and liver disease. Some Pi*Z allele carriers present cholestatic jaundice and cirrhosis. The Z type is associated with a secretion defect, which leads to deficiency of AAT and to the formation of intrahepatocytic inclusions in affected subjects. The diagnosis of AAT deficiency can be made by different techniques, including molecular analysis, although the final diagnosis should be done in conjunction with demonstration of the periodic acid-Schiff-positive globules on liver biopsy. In this study, specimens of 29 patients with cryptogenic cirrhosis between age 1 month and 18 years, and of 100 controls were submitted to polymerase chain reaction followed by digestion with TaqI enzyme. Five of the 29 patients had undergone liver transplantation. Three patients were heterozygous for the Pi*Z allele, and two were homozygous (allele frequency = 12.07%; 7/58). Among the controls, who represented the population of Porto Alegre, 1 in 100 individuals was heterozygous for the Pi*Z allele, resulting in an allele frequency of 0.5% (1/200). The high frequency of Pi*Z alleles among the patients indicates the usefulness of AAT molecular testing in children with cholestatic jaundice and cirrhosis.

Abstract
The article addresses the discovery of Biomphalaria occidentalis Paraense, a mollusk whose shell is indistinguishable from that of B. tenagophila, natural vector of Schistosoma mansoni. This reconstruction of the history of its discovery necessarily entails reference to the professional life of malacologist Wladimir Lobato Paraense. In addition to demonstrating how essential basic biology and taxonomy are in the epidemiology of mansoni schistosomiasis, the study also focuses on the discovery process itself and the socioeconomic factors which influenced it.

Abstract
Friedreich ataxia (FRDA), the most common autosomal recessive ataxia, is caused in 94% of cases by homozygous expansions of an unstable GAA repeat localised in intron 1 of the X25 gene. We have investigated this mutation in five Brazilian patients: four with typical FRDA findings and one patient with atypical manifestations, who was considered to have some other form of cerebellar ataxia with retained reflexes. The GAA expansion was detected in all these patients. The confirmation of FRDA diagnosis in the atypical case may be pointing out, as in other reports, that clinical spectrum of Friedreich's ataxia is broader than previously recognised and includes cases with intact tendon reflexes.

Abstract
A malacological survey to detect foci of transmission of schistosomiasis and other parasitic diseases was undertaken into water-courses from 13 municipalities of microregion of Belo Horizonte, MG, Brazil. From 1990 to 1996, 22,066 snails were collected. From those, 378 (1.7%) were found infected by trematodes: Biomphalaria glabrata (7,920), infected by Schistosoma mansoni (1.9%), Echinostomatidae (1.2%), Strigeidae (0.6%), Cercaria minense (0.1%) and Derogenidae (-0.1%); B. straminea (4,093) infected by Strigeidae (0.6%), Echinostomatidae (0.2%), Clinostomatidae (-0.1%) and two unidentified cercariae; B. tenagophila (1,338), infected by Strigeidae (0.1%) and Physa marmorata (1,776) by Echinostomatidae (1.6%). The snails Biomphalaria peregrina, B. occidentalis, B. schrammi, Drepanotrema depressissimum, D. lucidum, D. cimex, Physa cubensis, Lymnaea columella, Melania tuberculata, Idiopyrgus souleyetianus, Pomacea sp, Anodontites sp and Ancylidae were found noninfected. Snails from 9 municipalities were infected by S. mansoni and from 11 by other trematodes.

Abstract
A population of Biomphalaria occidentalis was found for the first time in the State of Minas Gerais. It was probably introduced into the Várzea das Flores dam, in the municipality of Contagem, the area of study, during fish stocking in 1985. There is the possibility of "competitive exclusion" between that species and B. glabrata, previously the only Biomphalaria found in the region. The present geographical distribution of B. occidentalis in Brazil is listed.

Abstract
Biomphalaria glabrata (control), B. tenagophila and B. straminea from our laboratory colonies iniciated with molluscs collected in the municipality of Belo Horizonte, MG (Brasil), were experimentally infected with first-stage larvae of Angiostrongylus costaricensis. The number of molluscs of each species exposed was 139, 77 and 149. About 25 days later, surviving molluscs were individually examined by artificial digestion. Of 87 B. glabrata examined, 62 (71.3%) were positive and between one and 61 third-stage larvae were found; of 42 B. tenagophila, 21 (50.0%) contained between one five third-stage larvae; and of 89 B. straminea, 69 (77.5%) presented between one and 72 third-stage larvae. The three molluscan species are susceptible to A. costaricensis infection, but B. glabrata and B. straminea are most suitable for maintaining the nematode cycle in laboratory.

Abstract
Em 1974 foram diagnosticados vários casos de leishmaniose tegumentar americana, no Município do Rio de Janeiro, RJ (Brasil). Naquela ocasião, foram usadas como medidas profiláticas o tratamento dos doentes e a dedetização dos domicílios e anexos, resultando na interrupção da transmissão. Com o aparecimento de novos casos, a partir de 1979, foram reestudadas algumas características de uma das localidades (Camorim) do mesmo município. De junho de 1979 a agosto de 1981, foram comprovados nessa localidade 19 casos novos de leishmaniose tegumentar americana (18 humanos e um em cão). Coletaram-se 1.149 flebótomos (11,4% fêmeas e 88,6% machos) com predomínio de Lutzomyia intermedia (95%). De acordo com o estudo dos casos, pressupõe-se que a transmissão tenha ocorrido no domicílio ou peridomicílio. Acredita-se, pois, que na área estudada, as medidas de controle, adotadas em 1974, foram eficientes por um período de aproximadamente quatro anos.

We registered Biomphalaria aff. glabrata (Say, 1818) from upper Pleistocene (or Holocene) based on paleontologic and stratigraphic data and in agreement with shell morphology. The shells came from Gruta das Onças, district of Caatinga do Moura, Jacobina country, state of Bahia. We also registered one more evidence of the ancient presence of water in the cave, which agree Cartelle & Bohorquez's (1982) hypothesis about the site.
