Effect of mechanical ventilation during cardiopulmonary bypass on oxidative stress: a randomized clinical trial.

BACKGROUND: Cardiopulmonary bypass (CPB) causes systemic oxidative stress response and endothelial damage in systemic organs. We investigated the effects of positive end-expiratory pressure (PEEP) and mechanical ventilation (MV) applications on oxidative stress in CPB. METHODS: Seventy-one patients were recruited and 60 completed the study. Randomized groups: MV off (Group 1); MV on, tidal volume (TV) at 3-4 mL.kg-1 (Group 2); MV on, TV at 3-4 mL.kg-1, PEEP at 5 cmH2O (Group 3), n = 20 in each group. As oxidative stress markers, we used glutathione peroxidase (GPx), total antioxidant status (TAS), total oxidant status (TOS), total and native thiol (TT, NT), malondialdehyde (MDA), and catalase. We also investigated the correlation between oxidative stress and postoperative intubation time. RESULTS: The postoperative GPx levels in Group 2 were higher than Group 3 (p = 0.017). In groups 2 and 3, TAS levels were higher postoperatively than intraoperatively (p = 0.001, p = 0.019, respectively). In Group 2, the TT levels were higher postoperatively than preoperatively and intraoperatively (p = 0.008). In Group 3, the postoperative MDA levels were higher than preoperatively (p = 0.001) and were higher than both postoperative levels of Group 1 and 2 (p = 0.043, p = 0.003). As the preoperative TAS (Group 2) decreased and the postoperative NT (Group 2) and catalase (Group 3) increased, the postoperative intubation time lengthened. CONCLUSION: MV ( 3-4 mL.kg-1) alone seems to be the most advantageous strategy. Prolonged postoperative intubation time was associated with both increased NT and catalase levels.

Comparison of the operative and postoperative effects of del Nido and blood cardioplegia solutions in cardiopulmonary bypass surgery.

OBJECTIVE: Our goal was to compare the operative and postoperative effects of del Nido cardioplegia (DN group) and blood cardioplegia (BC group) performed in cardiac surgery. METHODS: A total of 83 patients were included, separated into DN group and BC group. The operative and postoperative effects of the two groups were compared for the first 24 hours until extubation. The operative and postoperative complete blood count (CBC), biochemical values and clinical parameters were compared. RESULTS: The first control activated clotting time (ACT) levels in DN group patients were lower (P=0.003) during the operation. The amount of cardioplegia in DN group were lower than that in BC group (P=0.001). The pump outflow and postoperative lactate level of DN group were lower than those of BC group (P=0.005, P=0.018, respectively), as well as the amounts of NaHCO3 (P=0.006) and KCl (P=0.001) used during the operation. The same occurred with the first monocytes (Mo) and mean corpuscular volume (MCV) levels in the postoperative intensive care unit (P=0.006, P=0.002). However, the first glucose level and the eosinophil (Eo) level were higher in DN group (P=0.011, P=0.047, respectively). CONCLUSION: In the operative evaluation, the amount of cardioplegia, the first ACT levels, the pump outflow lactate level and the amounts of NaHCO3 and KCl in DN group were lower. In postoperative evaluation, measured level of lactate, Mo and MCV in DN group were all lower; their glucose and Eo levels were higher.

Effects of music therapy on pain and oxidative stress in oocyte pick-up: A randomized clinical trial / Efeitos da musicoterapia sobre dor e estresse oxidativo na aspiração folicular: estudo clínico randomizado

Abstract Background and objective: The aim was to investigate the effects of Turkish classical music on pain and oxidative stress in patients undergoing oocyte pick-up. Methods: The study was a randomized, controlled trial. The groups included Group NM (Non-Music), control group; Group PM, which comprised patients who listened to music before the operation; and Group CM, which comprised patients who listened to music both before and during the operation. Blood was drawn prior to the operation to measure the oxidative stress values. Pain, hemodynamic parameters, oxidative stress values were assessed postoperatively. Results: The number of patients requiring additional propofol was higher in Group PM than in Groups NM and CM (p = 0.003). The postoperative Visual Analog Scale (VAS) score were lower in Groups PM and CM than in Group NM (p = 0.001, p = 0.007) in the 1st and 60th minutes. The postoperative VAS score was lower in Group CM than in Group NM (p = 0.045) in the 5th minute. The postoperative additional analgesic requirements were lower in Groups PM and CM than in Group NM (p = 0.045). The postoperative blood glutathione peroxidase values were significantly higher in Groups PM and CM than in Group NM (p = 0.001). The postoperative catalase values were significantly higher in Groups PM and CM than in Group NM (p = 0.008 and p < 0.001). The preoperative malondialdehyde values were significantly lower in Groups PM and CM than in Group NM. The preoperative nitric oxide values were higher in Groups PM and CM than in Group NM (p < 0.001), whereas the postoperative nitric oxide values were lower in Groups PM and CM than in Group NM (p < 0.001). Conclusion: Turkish classical music has beneficial effects on pain and oxidative stress in oocyte pick-up patients.

Ultrasound-guided versus surgical transversus abdominis plane block in obese patients following cesarean section: a prospective randomised study / Bloqueio cirúrgico do plano transverso abdominal versus guiado por ultrassom em pacientes obesas após cesárea: estudo prospectivo e randomizado

Abstract Background and objectives Ultrasound-guided transversus abdominis plane block demonstrated efficacy in providing post-operative analgesia by prolonging the time to first analgesic requirement and reducing the total analgesic consumption. The surgical transversus abdominis plane block, a novel technique, can be performed safely in obese patients in whom muscle layers cannot be sufficiently exposed. Here, we compared applicability, efficacy and complications of surgical transversus abdominis plane and ultrasound-guided transversus abdominis plane blocks in obese pregnant women following cesarean section under general anesthesia. Methods Seventy-five pregnant women with pre- and post-pregnancy body mass index > 30 were randomized and allocated into two groups: Ultrasound-guided transversus abdominis plane block (UT group; n = 38) and surgical TAP block (ST group; n = 37). Visual analogue scale scores at post-operative 0, 2, 6, 12 and 24 hours (h), time to first analgesic requirement, total analgesic consumption amount in 24 h, post-operative side effects, complications and patient satisfaction were recorded. Results and conclusions Age, American Society of Anesthesiologist score, operative duration, body mass index, mean time to first analgesic requirement and total analgesic consumption in 24 h were similar between groups, while significant differences in pre- and post-pregnancy body mass index were observed between groups. Block procedure durations were 7 and 10 minutes in ST and UT groups, respectively. No significant differences in visual analogue scale scores were observed between the groups at all times; itching and nausea was observed in one (UT group) and four (UT and ST groups) patients, respectively. Surgical transversus abdominis plane block was safe in obese pregnant patients and provided similar post-operative analgesia to ultrasound-guided transversus abdominis plane block.

Resumo Justificativa e objetivos O bloqueio do plano transverso abdominal (TAP) guiado por ultrassom (US) demonstrou eficácia no fornecimento de analgesia no pós-operatório ao prolongar o tempo até a primeira necessidade de analgésico e reduzir o consumo total de analgésico. O bloqueio TAP cirúrgico (uma nova técnica) pode ser realizado com segurança em pacientes obesas nas quais as camadas musculares não podem ser suficientemente expostas. Comparamos a aplicabilidade, a eficácia e as complicações do bloqueio TAP cirúrgico e do bloqueio TAP-US em gestantes obesas submetidas à cesárea sob anestesia geral. Método Setenta e cinco mulheres grávidas com índice de massa corporal (IMC) pré e pós-gravidez > 30 foram randomicamente alocadas em dois grupos: bloqueio TAP-US (Grupo TAP-US, n = 38) e bloqueio TAP cirúrgico (Grupo TAP-C, n = 37). Os escores da escala visual analógica (VAS) nos tempos 0, 2, 6, 12 e 24 horas de pós-operatório, o tempo até a primeira necessidade de analgésico, o consumo total de analgésico em 24 horas, os efeitos colaterais no pós-operatório, as complicações e a satisfação do paciente foram registrados. Resultados e conclusões Idade, estado físico ASA, tempo cirúrgico, IMC, média de tempo até a primeira necessidade de analgésico e consumo total de analgésico em 24 horas foram semelhantes entre os grupos, enquanto diferenças significativas foram observadas entre os grupos em relação ao IMC pré- e pós-gravidez. As durações dos procedimentos de bloqueio foram de 7 e 10 minutos nos grupos TAP-US e TAP-C, respectivamente. Não houve diferença significativa nos escores VAS entre os grupos em todos os momentos; prurido e náusea foram observados em um paciente (Grupo TAP-US) e em quatro (Grupo TAP-C), respectivamente. O bloqueio TAP cirúrgico foi seguro nas pacientes grávidas obesas e forneceu analgesia similar à do bloqueio TAP-US no pós-operatório.
