A Retrospective Investigation of Patient- and Procedure-Related Factors Associated with Cardiorespiratory Complications in Pediatric Dental Patients Undergoing Deep Sedation.

Purpose: The purposes of this retrospective study were to investigate the incidence of cardiac and respiratory complications in pediatric patients undergoing dental procedures with deep propofol sedation and examine the factors that may lead to the development of these complica- tions. Methods: This study was carried out using the records of 421 pediatric patients who received dental treatment with deep sedation. Previously recorded cardiac/respiratory complications were noted. In addition, factors such as age, gender, body mass index (BMI), propofol induction/ infusion/total dose, operation duration, and the presence of comorbidities, which were investigated whether they affect these complications, were also noted. Data were analyzed with Mann-Whitney U, chi-square, and Fisher exact tests using univariable and multivariable logistic regression analyses. A level of five percent was considered to indicate statistical significance. Results: There were no significant differences between the cases with and without complications in terms of gender, age, BMI, total propofol dose, and operation time (P=0.887, P=0.827, P=0.213, P=0.581, and P=0.081, respectively). According to the multivariable logistic regression analysis, trisomy 21, heart disease, and asthma were found to be significant risk factors for the development of these complications (odds ratios equal 9.776, 3.257, and 14.646, respectively, 95 percent confidence interval; 3.807-25.100, 1.095-9.690, 4.110-52.188, respectively). Conclusion: Considering the limitations of this study, to minimize cardio-respiratory complications it is recommended that patients with comorbidities should not be managed with deep sedation and an open airway.

[Influence of methylprednisolone on the reversal time of sugammadex: a randomized clinical trial]. / Influência da metilprednisolona no tempo de reversão do sugammadex: estudo clínico randomizado.

BACKGROUND AND OBJECTIVES: Sugammadex is a modified gamma-cyclodextrin that reverses the effects of aminosteroidal neuromuscular blocking agents. Likewise, some steroid molecules, such as toremifene, fusidic acid, and flucloxacillin, can also be encapsulated by sugammadex. Methylprednisolone, which is a synthetic steroid used commonly for airway oedema prophylaxis, can also be encapsulated by sugammadex. The objective of this study was to compare the recovery times of sugammadex for reversing rocuronium-induced moderate neuromuscular blockade in those who received intraoperative 1 mg.kg-1 methylprednisolone or saline. METHOD: This single-centered, randomized, controlled, prospective study included 162 adult patients undergoing elective ear-nose-throat procedures (aged from 18-65, an ASA physical status I-II, a BMI less than 30 kg.m-2, and not taking steroid drug medication) with propofol, remifentanyl, rocuronium and sevoflurane. Neuromuscular monitoring was performed using calibrated acceleromyography. The Control Group (Group C) received 5 mL of saline, while the Methylprednisolone Group (Group M) received 1 mg.kg-1 of methylprednisolone in 5mL of saline just after induction. After the completion of surgery, regarding the TOF count, two reappeared spontaneously and 2 mg.kg-1 sugammadex was administered to all patients. Recovery of the TOF ratio to 0.9 was recorded for both groups, and the estimated recovery time to reach a TOF ratio (TOFr) of 0.9 was the primary outcome of the study. RESULTS: Median time to TOFr = 0.9 was for 130.00 s (range of 29-330) for Group C and 181.00 s (100-420) for Group M (p < 0.001). The differences between the two groups were statistically significant. CONCLUSION: When using 2 mg.kg-1 of sugammadex to reverse rocuronium-induced neuromuscular blockade in patients who received 1 mg.kg-1 of intraoperative methylprednisolone, demonstrated delayed recovery times.

[Thoracic outlet syndrome: A case of scalene muscle hypertrophy in long-term follow-up of diagnosis of cervical discopathy]. / Uzun süre servikal diskopati tanisi ile izlenen skalen kas hipertrofisinin neden oldugu torasik outlet sendromu.

Described in this article is diagnosis and treatment of mixed type of thoracic outlet syndrome (TOS) resulting from scalene muscle hypertrophy. Many diseases should be considered in the differential diagnosis to definitively diagnose this syndrome, and it is necessary to ask about activities of daily life, in addition to adding provocative tests to physical examination and examining electrophysiological and imaging results. Once diagnosed, even if complaints decrease with conservative treatment, surgery may be required. However, in patients diagnosed late, despite decrease in complaints after surgery, neurological deficit may remain.

Resumo Justificativa e objetivos: Sugammadex é uma gama-ciclodextrina modificada que reverte os efeitos de agentes de bloqueio neuromuscular aminoesteroides. Da mesma forma, algumas moléculas esteroides, como toremifene, ácido fusídico e flucloxacilina, podem ser encapsulados pelo sugammadex. A metilprednisolona, esteroide sintético usado geralmente para a profilaxia de edema de vias aéreas, também pode ser encapsulada pelo sugammadex. O objetivo do estudo foi comparar os tempos de recuperação do sugammadex na reversão de bloqueio neuromuscular moderado induzido pelo rocurônio em pacientes em que foi administrado 1 mg.kg-1 de metilprednisolona ou solução salina no período intraoperatório. Método: Este estudo prospectivo, randomizado, controlado, unicêntrico incluiu 162 pacientes adultos (idades de 18-65, ASA I-II, IMC abaixo de 30 kg.m-2, e não usando medicação esteroide) submetidos à anestesia geral para procedimento eletivo de otorrinolaringologia com propofol, remifentanil, rocurônio e sevoflurano. A monitorização neuromuscular foi realizada usando aceleromiógrafo calibrado. O grupo controle (Grupo C) recebeu 5 mL de solução salina, enquanto o grupo metilprednisolona (Grupo M) recebeu 1 mg.kg-1 de metilprednisolona em 5 mL de solução salina logo após a indução. Ao término da cirurgia, em relação à contagem do número de respostas à sequência de quatro estímulos (TOFc), dois pacientes mostraram recuperação espontânea e todos os pacientes receberam 2 mg.kg-1 de sugammadex. A recuperação da razão T4/T1 (TOFr) para 0,9 foi registrada nos dois grupos, e o desfecho primário do estudo foi o tempo estimado de recuperação, momento em que a razão TOFr alcançou o valor de 0,9 (TOFr = 0.9). Resultados: O tempo mediano para TOFr = 0,9 foi 130 s (29-330) para o Grupo C e 181s (100-420) para o Grupo M (p < 0,001). As diferenças entre os dois grupos foi estatisticamente significante. Conclusões: Pacientes que receberam 1 mg.kg-1 de metilprednisolona no intraoperatório apresentaram tempo de recuperação mais prolongado após o uso de 2 mg.kg-1 de sugammadex para reverter o bloqueio neuromuscular induzido pelo rocurônio.
