RESUMO

AIM: The issue of preemptive or preventive use of paracetamol still raises questions in terms of multimodal analgesia in cesarean delivery. A combination of paracetamol and opioid is commonly used for pain management after cesarean delivery. This study aims to compare postoperative pain level and analgesic consumption when using paracetamol at two different perioperative times in cesarean section. MATERIAL AND METHODS: Sixty patients recruited for elective cesarean section under general anesthesia were included in this prospective study. Patients were randomly assigned to receive iv 1 g paracetamol 15 minutes before incision (Group PE) or after delivery of newborn (Group PV). Visual analog scale (VAS) values, 24-hour morphine consumption, additional analgesic requirement, side effects, and patient and surgeons' satisfaction were recorded. RESULTS: Demographic data and hemodynamic values of the patients were similar in both groups. There was no differences between groups in terms of VAS scores at rest and during movement, additional analgesic requirement during the postoperative 1st hour, and 24-hour total morphine consumption. There was no difference in side effects, and patient and surgeon satisfaction scores postoperatively. CONCLUSIONS: Preemptive and preventive use of paracetamol provides the same quality of analgesia and opioid sparing effect without increasing the frequency of adverse effects. KEY WORDS: Analgesia, Cesarean Section, General Anesthesia, Preemptive, Preventive.

RESUMO

Abstract Background: Pain management in hip fracture patients is of great importance for reducing postoperative morbidity and mortality. Multimodal techniques, including peripheral nerve blocks, are preferred for postoperative analgesia. Older-old hip fracture patients with high ASA scores are highly sensitive to the side effects of NSAIDs and opioids. Our aim was to investigate the effectiveness of the recently popularized Supra-Inguinal Fascia Iliaca Block (SIFIB) in this population. Methods: Forty-one ASA III-IV patients who underwent SIFIB + PCA (G-SIFIB) or PCA alone (Group Control: GC) after general anesthesia were evaluated retrospectively. In addition to 24-hour opioid consumption, Visual Analog Scale (VAS) scores, opioid-related side effects, block-related complications, and length of hospital stay were compared. Results: Twenty-two patients in G-SIFIB and 19 patients in GC were evaluated. The postoperative 24-hour opioid consumption was lower in G-SIFIB than in GC (p < 0.001). There was a statistically significant reduction in VAS scores at the postoperative 1st, 3rd, and 6th hours at rest (p < 0.001) and during movement (p < 0.001 for the 1st and 3rd hours, and p = 0.02 for the 6th hour) in G-SIFIB compared to GC. There was no difference in pain scores at the 12th and 24th hours postoperatively. While there was no difference between the groups in terms of other side effects, respiratory depression was significantly higher in GC than in G-SIFIB (p = 0.01). Conclusion: The SIFIB technique has a significant opioid-sparing effect and thus reduces opioid-related side effects in the first 24 hours after hip fracture surgery in older-old patients.

RESUMO

OBJECTIVE: To compare the early-term patency and complication rates of the end-to-side anastomosis techniques parachute and diamond-shaped techniques in arteriovenous fistulas. STUDY DESIGN: Prospective randomised study. PLACE AND DURATION OF STUDY: Department of General Surgery, Adana Baskent University Application and Research Hospital, Adana, Turkey, between October 2014 and January 2015. METHODOLOGY: Patients with end stage renal disease who underwent arteriovenous fistula creation for hemodialysis were grouped into two according to the anastomosis technique performed. Group 1 was composed of the patients undergoing the standard parachute technique and Group 2 consisted of the patients operated with the diamond-shaped anastomosis technique. The two groups were compared with each other with respect to clinical and demographic data, operative and postoperative variables, and complication and patency rates. RESULTS: A total of 56 patients underwent arteriovenous fistula creation. The overall complication rate was 12.5%. The early-term patency rate was higher in the diamond-shaped anastomosis technique than the standard parachute end- to-side anastomosis technique. Effective dialysis was established after 4 weeks in 48 (85.7%) patients in the overall study group, 23 (82.1%) in Group 1, and 25 (89.2%) in Group 2. However, there was no significant difference between both the techniques with respect to effectiveness of dialysis. CONCLUSION: Both end-to-side anastomosis techniques have their own advantages and disadvantages. Using a patient- specific suitable technique rather than a standard technique would be more appropriate in arteriovenous fistulas formation.

RESUMO

Özmete Ö, Sener M, Bali Ç, Çaliskan E, Aribogan A. Congenital insensitivity to pain: How should anesthesia be managed? Turk J Pediatr 2017; 59: 87-89. Congenital insensitivity to pain syndrome is a rare, sensorial and autonomic neuropathy characterized by unexplained fever, insensitivity to pain and anhidrosis. Patients may require anesthesia even for minor surgical procedures due to mental retardation and trauma arising from self- mutilating behavior. A child diagnosed with congenital insensitivity to pain syndrome was scheduled for gastric endoscopy under sedation due to suspected ingestion of a household cleaning disinfectant. Deep sedation was achieved, and spontaneous respiration was maintained. We did not encounter any complications. There is limited data regarding the safe anesthesia management in these patients because of the rarity of the disease. Therefore, we think that more clinical experience, case reports and studies are needed to establish the appropriate anesthesia management.

RESUMO

STUDY OBJECTIVE: This study evaluated the postoperative analgesic efficacies of fascia iliaca block and periarticular drug injection techniques after TKA (total knee arthroplasty) surgeries. DESIGN: Prospective, randomized clinical trial. SETTING: University Teaching and Research Center. PATIENTS: Seventy-one American Society of Anesthesiologists (ASA) I-III patients between 48 and 70 years of age who underwent total knee arthroplasty were randomized. INTERVENTIONS: Tenoxicam (20 mg) was administered intramuscularly to both groups of patients 30 minutes before surgery. Patients were randomized into two groups to receive fascia iliaca block before the induction of anesthesia (Group FI) or periarticular drug injection during the surgery (Group PI). All surgeries were performed under general anesthesia using standard techniques. Postoperative analgesia was provided with patient-controlled intravenous morphine. MEASUREMENTS: Total morphine consumption was the primary outcome measure and was recorded postoperatively at 1, 2, 6, 12 and 24 hours. Pain levels at rest and on movement (knee flexion) were evaluated using the Visual Analogue Scale (VAS) and recorded at the same time points. Patients' demographics, rescue analgesic demands, side effects, hemodynamics, and satisfaction scores were also recorded. MAIN RESULTS: The groups had similar VAS scores both at rest and on movement (P>.05). However, the amount of cumulative morphine and use at each follow-up period was higher in Group PI (P<.0001). The groups did not differ significantly in rescue analgesic use or side effects, such as nausea/vomiting, hemodynamic variables, and patient satisfaction scores (P>.05). CONCLUSIONS: Fascia iliaca block may be used as an alternative method to periarticular injection, and it effectively reduces the amount of morphine used to relieve post-TKA pain.

RESUMO

STUDY OBJECTIVE: To evaluate the efficacy and safety of sugammadex in reversing profound neuromuscular block induced by rocuronium in infant patients. DESIGN: Retrospective observational study. SETTING: University teaching hospital. PATIENTS: Twenty-six infants (2-12 months of age; 3-11 kg) with an American Society of Anesthesiologists classification I, II, or III who were scheduled to undergo neurosurgical procedures were included in the study. INTERVENTIONS: Anesthesia was induced with 5 mg/kg thiopental, 1 µg/kg fentanyl and 0.6 mg/kg rocuronium. Sevoflurane was administered to all patients after intubation. METHODS: The neuromuscular block was monitored with acceleromyography using train-of-four (TOF) stimuli. Patients received additional doses of rocuronium to maintain a deep block during surgery. If profound neuromuscular block (TOF, 0) persisted at the end of the surgery, 3mg/kg sugammadex was administered. MEASUREMENTS: The demographic data, surgeries, and anesthetic agents were recorded. The time from sugammadex administration to recovery of neuromuscular function (TOF ratio, >0.9) and complications during and after extubation were also recorded. MAIN RESULTS: Twenty-six infants who had a deep neuromuscular block (TOF, 0) at the end of surgery received 3 mg/kg sugammadex. The mean recovery time of the T4/T1 ratio of 0.9 was 112 seconds. No clinical evidence of recurarization or residual curarization was observed. CONCLUSIONS: The efficacy and safety of sugammadex were confirmed in infant surgical patients for reversal of deep neuromuscular block induced by rocuronium.

RESUMO

STUDY OBJECTIVE: To evaluate the analgesic effect of preoperative single dose intravenous paracetamol on postoperative pain and analgesic consumption within 24hours after elective cesarean surgery. DESIGN: Prospective, randomized, double-blind, placebo-controlled clinical trial. SETTING: University Teaching Hospital. PATIENTS: American Society of Anesthesiologists (ASA) I and II 60 patients between 18-40years of age who were scheduled to undergo elective cesarean section. INTERVENTIONS: Patients were randomized into two groups to receive either intravenous 1g paracetamol (100mL) (Group P) or 0.9% NaCl solution (100mL) (Group C) 15minutes before the induction of general anesthesia. After delivery of newborn 0.15mg kg(-1) morphine was administered to all patients in both groups. Postoperative analgesia was provided with patient-controlled intravenous analgesia with morphine in the postoperative period. MEASUREMENTS: Pain which is the primary outcome measure was assessed at 15th, 30th minutes and 1st, 2nd, 4th, 6th, 12th, 24th hours by the Visual Analogue Scale. Patients' demographics, hemodynamics, Apgar score, additional analgesic requirement, side effects, patients' satisfaction and postoperative total morphine consumption within 24hours were recorded. MAIN RESULTS: Median visual analogue scale for pain in Group P was significantly lower compared to Group C at all time points except for the score at 24th h postoperatively (P<.05). Additional analgesic requirement during postoperative first hour was lower in Group P (P<.05). Total morphine consumption was higher in Group C compared with Group P (P<.05). There was no difference between groups with respect to Apgar scores, side effects, and patient satisfaction (P>.05). CONCLUSIONS: Preoperative use of single-dose intravenous 1g paracetamol was found to be effective in reducing the severity of pain and opioid requirements within 24hours after cesarean section.

RESUMO

ABSTRACT BACKGROUND AND OBJECTIVES: Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used to control arthroscopic pain. Addition of oral effective opioid "codeine" to NSAIDs may be more effective and decrease parenteral opioid consumption in the postoperative period. The aim of this study was to compare the efficacy and side effects of naproxen sodium and a new preparation naproxen sodium-codeine phosphate when administered preemptively for arthroscopic meniscectomy. METHODS: Sixty-one patients were randomized into two groups to receive either oral naproxen sodium (Group N) or naproxen sodium-codeine phosphate (Group NC) before surgery. The surgery was carried out under general anesthesia. Intravenous meperidine was initiated by patient-controlled analgesia (PCA) for all patients. The primary outcome measure was pain score at the first postoperative hour assessed by the Visual Analogue Scale (VAS). Sedation assessed by Ramsey Sedation Scale, first demand time of PCA, postoperative meperidine consumption, side effects and hemodynamic data were also recorded. RESULTS: The groups were demographically comparable. Median VAS scores both at rest and on movement were significantly lower in Group NC compared with Group N, except 18th hour on movement (p < 0.05). The median time to the first demand of PCA was shorter in Group N compared with Group NC (p < 0.001). Meperidine consumption was higher in Group N compared with Group NC (p < 0.001). There was no difference between groups with respect to side effects (p > 0.05). CONCLUSIONS: The combination of naproxen sodium-codeine phosphate provided more effective analgesia than naproxen sodium and did not increase side effects.


RESUMO JUSTIFICATIVA E OBJETIVOS: Os anti-inflamatórios não esteroides (AINEs) são frequentemente usados para controlar a dor após artroscopia. A adição de um opiáceo oral eficaz (codeína) aos AINEs pode ser mais efetiva e diminuir o consumo de opiáceo parenteral no pós-operatório. O objetivo deste estudo foi comparar a eficácia e os efeitos colaterais de naproxeno sódico e uma nova preparação, naproxeno sódico-fosfato de codeína, quando administrados preventivamente para meniscectomia artroscópica. MÉTODOS: Foram randomicamente divididos em dois grupos 61 pacientes para receber naproxeno sódico por via oral (Grupo N) ou naproxeno sódico-fosfato de codeína (Grupo NC) antes da cirurgia. A cirurgia foi feita sob anestesia geral. Meperidina intravenosa foi iniciada por meio de analgesia controlada pelo paciente (ACP) para todos os pacientes. O desfecho primário foi o escore de dor na primeira hora de pós-operatório, avaliada com a escala visual snalógica (EVA). A sedação foi avaliada com a escala de sedação de Ramsey. A primeira demanda de ACP, o consumo de meperidina no pós-operatório, os efeitos colaterais e os dados hemodinâmicos também foram registrados. RESULTADOS: Os grupos foram demograficamente comparáveis. As medianas dos escores EVA tanto em repouso quanto em movimento foram significativamente menores no Grupo NC comparado com o Grupo N; exceto para movimento na avaliação de 18 horas (p < 0,05). A mediana do tempo até a primeira demanda de ACP foi menor no Grupo N em comparação com o Grupo NC (p < 0,001). O consumo de meperidina foi maior no Grupo N em comparação com o Grupo NC (p < 0,001). Não houve diferença entre os grupos em relação aos efeitos colaterais (p > 0,05). CONCLUSÕES: A combinação de naproxeno sódico-fosfato de codeína forneceu analgesia mais efetiva que naproxeno sódico, sem aumentar os efeitos colaterais.

RESUMO

ABSTRACTBACKGROUND AND OBJECTIVE: Sedation in dialysis dependent end-stage renal disease patients requires caution as a result of performing high doses of sedatives and its complications. Multidrug sedation regimens might be superior and advantage on lesser drug consumption and by the way adverse events which occur easily in end-stage renal disease patients. We evaluated the effects of dexmedetomidine premedication on propofol consumption, sedation levels with Observer's Assessment of Alertness and Sedation scores and the bispectral index and the hemodynamic changes, potential side effects in geriatric patients with end-stage renal disease who underwent hip fracture surgery under spinal anesthesia.METHOD: In this randomized, controlled, double-blind study 60 elderly patients (age ≥ 65 years) with end-stage renal disease and hip fracture scheduled for anterograde femoral intramedullary nailing were assigned to groups that received either intravenous saline infusion (Group C) or dexmedetomidine 0.5 g/kg/10 min infusion for premedication (Group D). All the patients received propofol infusion after the induction of the spinal anesthesia.RESULTS: Total propofol consumption, propofol dose required for targeted sedation levels according to Observer's Assessment of Alertness and Sedation scores and bispectral index levels, recovery times were significantly lower in Group D (p < 0.001). The time to reach to Observer's Assessment of Alertness and Sedation score 4 and to achieve bispectral index ≤ 80 was significantly lower in Group C compared with Group D (p < 0.001). Adverse events were similar in both groups.CONCLUSION: Dexmedetomidine premedication lowers intraoperative propofol consumption to maintain targeted level of sedation. Therefore low dose dexmedetomidine premedication in addition to propofol infusion might be an alternative in geriatric patients with end-stage renal disease for sedation.


RESUMOJUSTIFICATIVA E OBJETIVO: A sedação em paciente dependente de diálise com doença renal em estágio terminal (DRET) requer cautela como resultado da administração de altas doses de sedativos e suas complicações. Os regimes de sedação com múltiplas drogas podem ser superiores e vantajosos em relação ao consumo menor de drogas e aos eventos adversos que ocorrem facilmente em pacientes com DEET. Avaliamos os efeitos da pré-medicação com dexmedetomidina sobre o consumo de propofol, os níveis de sedação com os escores da Observer's Assessment of Alertness and Sedation (OAA/S) e do índice bispectral (BIS), as alterações hemodinâmicas e os potenciais efeitos colaterais em pacientes geriátricos com DRET submetidos à cirurgia para fratura de quadril sob raquianestesia.MÉTODO: Neste estudo randômico, controlado e duplo-cego, 60 pacientes idosos (idade ≥ 65 anos), com DRET e fratura de quadril, agendados para fixação intramedular de haste femoral anterógrada foram designados para grupos para receberam infusão intravenosa de solução salina (Grupo C) ou pré-medicação com infusão de 0,5 mg kg/10 min de dexmedetomidina (DEX) (Grupo D). Todos os pacientes receberam infusão de propofol após a indução da raquianestesia.RESULTADOS: O consumo total de propofol, a dose de propofol necessária para os níveis-alvo de sedação de acordo com os escores da OAA/S, os valores do BIS e os tempos de recuperação foram significativamente menores no Grupo D (p < 0,001). O tempo para atingir o escore 4 na OAA/S e valores BIS ≤ 80 foi significativamente inferior no Grupo C em comparação com o Grupo D (p < 0,001). Os eventos adversos foram semelhantes em ambos os grupos.CONCLUSÃO: A pré-medicação com dexmedetomidina reduz o consumo de propofol no intraoperatório para manter o nível-alvo de sedação. Portanto, a pré-medicação com DEX em dose baixa em combinação com infusão de propofol pode ser uma opção para sedação em pacientes geriátricos com DRET.

RESUMO

BACKGROUND AND OBJECTIVE: Sedation in dialysis dependent end-stage renal disease patients requires caution as a result of performing high doses of sedatives and its complications. Multidrug sedation regimens might be superior and advantage on lesser drug consumption and by the way adverse events which occur easily in end-stage renal disease patients. We evaluated the effects of dexmedetomidine premedication on propofol consumption, sedation levels with Observer's Assessment of Alertness and Sedation scores and the bispectral index and the hemodynamic changes, potential side effects in geriatric patients with end-stage renal disease who underwent hip fracture surgery under spinal anesthesia. METHOD: In this randomized, controlled, double-blind study 60 elderly patients (age≥65 years) with end-stage renal disease and hip fracture scheduled for anterograde femoral intramedullary nailing were assigned to groups that received either intravenous saline infusion (Group C) or dexmedetomidine 0.5µg/kg/10min infusion for premedication (Group D). All the patients received propofol infusion after the induction of the spinal anesthesia. RESULTS: Total propofol consumption, propofol dose required for targeted sedation levels according to Observer's Assessment of Alertness and Sedation scores and bispectral index levels, recovery times were significantly lower in Group D (p<0.001). The time to reach to Observer's Assessment of Alertness and Sedation score 4 and to achieve bispectral index≤80 was significantly lower in Group C compared with Group D (p<0.001). Adverse events were similar in both groups. CONCLUSION: Dexmedetomidine premedication lowers intraoperative propofol consumption to maintain targeted level of sedation. Therefore low dose dexmedetomidine premedication in addition to propofol infusion might be an alternative in geriatric patients with end-stage renal disease for sedation.
