RESUMO

Objectives This study evaluated pain intensity in elderly subjects with hip fractures admitted to the emergency sector and undergoing preoperative pericapsular nerve group (PENG) block. Additionally, the degree of tolerable hip flexion was assessed. Methods A prospective, randomized, and controlled clinical trial with parallel groups. The control group consisted of elderly subjects with hip fractures undergoing standardized intravenous systemic analgesia. The intervention group consisted of elderly patients with hip fractures undergoing PENG block and standardized systemic analgesia. The groups were evaluated at rest and during movement using the Pain Assessment in Advanced Dementia (PAINAD) scale. We determined pain intensity and reduction, in addition to the degree of tolerable flexion of the fractured hip. All patient assessments occurred before the medication or block administration and at 45 minutes, 12, 24, and 36 hours postmedication or block. Results Preoperatively and 24 hours after PENG block, elderly subjects with hip fracture showed a significant reduction in pain at rest or movement compared to control patients ( p < 0.05), with 60% of patients assessed at rest demonstrating desirable pain reduction (≥50%) and only 13.3% of the control group achieving the desired pain reduction. During movement, after undergoing PENG block, 40% of subjects demonstrated the desired pain reduction and no patient from the control group. The intervention group also showed a significant improvement in the tolerable hip flexion group ( p < 0.05). Conclusion Preoperative PENG block in elderly subjects with hip fractures admitted to the emergency sector provided a significant reduction in pain compared with the control group.

RESUMO

BACKGROUND: The antiemetic effectiveness of olanzapine, as a prophylactic off-label antiemetic drug, for Postoperative Nausea and Vomiting (PONV) is unknown. In this systematic review and meta-analysis, the authors evaluate the efficacy and side effects of olanzapine as a prophylactic antiemetic in adult patients who undergo general anesthesia and assess adverse effects. METHODS: A systematic search was done on electronic bibliographic databases in July 2023. Randomized controlled trials of olanzapine as a prophylactic antiemetic for PONV in adults who underwent general anesthesia were included. The authors excluded non-RCTs and retracted studies. The authors set no date of publication or language limits. The outcomes were the incidence of PONV within 24 h postoperatively and the safety of olanzapine. The risk of bias was assessed according to the tool suggested by the National Heart, Lung, and Blood Institute. RESULTS: Meta-analysis included 446 adult patients. Olanzapine reduced on average 38 % the incidence of PONV. The estimated risk ratio (95 % CI) of olanzapine versus control was 0.62 (0.42-0.90), p = 0.010, I2 = 67 %. In the subgroup meta-analysis, doses of olanzapine (10 mg) reduced on average 49 % of the incidence of PONV (RR = 0.51 [0.34-0.77], p = 0.001, I2 = 31 %). CONCLUSIONS: This systematic review with meta-analysis indicated that olanzapine as a prophylactic antiemetic alone or combined with other antiemetic agents reduced the incidence of postoperative nausea and vomiting. However, this conclusion must be presented with some degree of uncertainty due to the small number of studies included. There was a lack of any evidence to draw conclusions on side effects.

Resumo Objetivos Este estudo avaliou a intensidade da dor em idosos acometidos por fratura do quadril internados no setor de emergência e submetidos ao Pericapsular Nerve Group (PENG) block no pré-operatório. Ademais, o grau de flexão tolerável do quadril foi avaliado. Métodos Ensaio clínico, prospectivo, aleatorizado e controlado em grupos paralelos. O grupo controle consiste em idosos com fratura do quadril, submetidos à analgesia sistêmica endovenosa padronizada. O grupo intervenção consiste em idosos com fratura do quadril submetidos ao PENG block e analgesia sistêmica padronizada. Os grupos foram avaliados em repouso e durante o movimento pela escala de dor Pain Assessment in Advance Dementia (PAINAD). Aferiram-se intensidade da dor e redução álgica, assim como o grau de flexão tolerável do quadril fraturado. Todos os pacientes foram avaliados previamente à administração de medicação ou bloqueio e aos 45 minutos, 12, 24 e 36 horas pós-medicação ou bloqueio. Resultados No pré-operatório e 24 horas após o PENG block, idosos com fratura do quadril apresentaram redução significativa da dor em repouso ou movimento em comparação com o controle (p< 0,05), com 60% dos pacientes avaliados em repouso, demonstrando a redução álgica desejável de ≥ 50% e apenas 13,3% do grupo controle com redução álgica desejável. Durante o movimento, após o PENG block, 40% demonstraram redução álgica desejada e nenhum paciente do grupo controle apresentou a redução desejada. Verificou-se, também, no grupo intervenção a melhora significativa da flexão tolerável do quadril (p < 0,05). Conclusão O PENG block no pré-operatório de idosos com fratura do quadril, internados no setor de emergência, proporcionou redução significativa da dor em comparação ao grupo controle.

RESUMO

OBJECTIVES: To evaluate the addition of a fourth antiemetic intervention in patients at high risk for postoperative nausea and vomiting (PONV). METHODS: High-risk patients (Apfel score 3 or 4) scheduled for unilateral mastectomy were randomly allocated in one of two groups, oral aprepitant (oral aprepitant 80 mg, intravenous dexamethasone 8 mg, and palonosetron 0.075 mg) and oral placebo (oral placebo, intravenous dexamethasone 4 mg, and palonosetron 0.075 mg). Patients and caregivers were blinded to the group assignments. The primary efficacy endpoints included the incidence of nausea and vomiting, and the secondary endpoints included use of rescue antiemetics during a 48-hour postoperative period. ClinicalTrials.gov: NCT02431286. RESULTS: One hundred patients were enrolled in this study and 91 were analyzed, 48 in group A and 43 in group P. No patient presented with nausea or vomiting in the first 2 hours after surgery. From the 2nd to the 6th hour, the incidence of PONV was 8.33% in group A and 9.30% in group P. In the first 24 hours, the incidence of PONV was 27.08% in the group A and 20.93% in group P. From the 24th to the 48th hour, the incidence of PONV was 8.33% in group A and 13.95% in group P. There were no statistically significant differences in PONV between groups. CONCLUSION: The addition of aprepitant as a third antiemetic resulted in no significant reduction in the incidence of PONV in this population. However, the incidence of PONV was reduced in relation to the general population.

RESUMO

BACKGROUND AND OBJECTIVES: Jeune Syndrome or Asphyxiating Thoracic Dystrophy is a recessive autosomal disease. This syndrome is characterized by a bone dysplasia with varied abnormalities: thoracic, pancreatic, cardiac, hepatic, renal and retinal. Patients' age when the clinical condition is experienced correlates with the disease severity. These patients experience polychondrodystrophy with large, short, horizontal ribs and irregular costochondral junctions resulting in a rigid and reduced thoracic cage with varied respiratory injury level. CASE REPORT: Male patient, 4 months-old, 7kg, suffering with Asphyxiating Thoracic Dystrophy, intubated and presented with reduced thoracic cage. Echocardiogram: mild pulmonary hypertension. Chest tomography: pulmonary hypoplasia. Patient submitted to bilateral thoracoplasty and thoracotomy with general anesthesia. Anesthesia maintenance: sufentanil e sevoflurane continuous infusion. Ventilation parameters: pressure-cycled mechanical ventilation. Thorax opening provided improvement of the ventilation parameters, but after thoracic prosthesis placement, ventilation was limited. Reduction of the thoracic prosthesis was considered with consequent improvement of ventilation. CONCLUSIONS: Diagnosis of all present abnormalities is essential for the correct anesthetic management. Observation was necessary to adequate pre- and post-thoracotomy/thoracoplasty ventilation and to maintain patient hemodynamically stable. Pressure-cycled mechanical ventilation is the most adequate type of ventilation to overcome the mechanical barrier. In the intraoperative setting, the ideal is to maintain the inspiratory pressure peak as low as possible to minimize the risk of barotrauma, venous return impairment and reduced cardiac output.
