The impact of multimodal analgesia timing on postoperative pain in cesarean delivery. A prospective randomized study.

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.

Spinal anesthesia in surgical treatment of lumbar spine tumors.

OBJECTIVE: This study aims to show the feasibility of spinal anesthesia in lumbar spinal tumor surgery; share our data and experience. PATIENTS AND METHODS: A retrospective review of 14 patients with high risk for general anesthesia due to severe comorbidities was carried out. Patients who underwent surgeries under spinal anesthesia for lumbar vertebral column or spinal cord tumors at a single center between 2007-2019 were evaluated. The final pathological diagnosis, operation time, and surgical procedures were analyzed. Also, preoperative and postoperative advantages and disadvantages were determined. A comparison was performed with other 184 patients who were operated for spinal tumors in the same period under general anesthesia. RESULTS: Maximum operation time was found 220 min, and the average operation time was 166 min. The most primary diagnosis was vertebral column metastasis. The mean age was 65.5 years. None of the patients required general anesthesia during surgery; however, two patients needed additional spinal anesthesia preoperatively, which was performed by the surgeon. Lumbar decompression and fusion were the most performed procedures. CONCLUSION: Spinal anesthesia is a feasible and useful method of anesthesia in lumbar spinal tumor surgery for especially elderly patients with American Society of Anesthesiologists (ASA) 3 or 4 score and high risk of general anesthesia.

Congenital insensitivity to pain: How should anesthesia be managed?

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.

The use of flexible laryngeal mask airway for Adenoidectomies: An experience of 814Paediatric patients.

OBJECTIVE: To assess flexible laryngeal mask airway (F-LMA) use during pediatric adenoidectomies in terms of patient safety, comfort, complication rates and surgeon satisfaction levels. METHODS: Patients who had undergone an elective adenoidectomy after receiving general anesthesia using F-LMA from June 2012 to November 2015 were included. Patients' demographics and the incidence of perioperative complications were investigated. The surgeon's satisfaction level was also evaluated by questionnaire. RESULTS: Eight hundred fourteen patient were included in the study. Conversion from F-LMA to an endotracheal tube was carried out in two patients (0.2%). Airway complications were identified in two patients. The mean duration of stay in the postoperative anesthesia care unit was 17 minutes. All patients were discharged the same day. According to the otolaryngologists F-LMA applications provide a significant reduction in the processing time (100%), postoperative patient comfort is better than when using endotracheal intubation (83.3%) and the consensus was that there should be a complete continuation of the use of the F-LMA (100%) in subsequent adenoidectomies. CONCLUSION: Our data show that the use of F-LMA for pediatric adenoidectomies has well tolerability profile and resulted in a lower incidence of complications. We think that the use of F-LMA for pediatric adenoidectomy is safer, simpler and speeder method.

[Application of spinal anesthesia in a pediatric patient with Duchenne's muscular dystrophy]. / Duchenne musküler distrofili çocuk hastada spinal anestezi uygulamasi.

Duchenne's muscular dystrophy (DMD) is a neuromuscular disease with a progressive course. It is the most common and most severe muscular dystrophic disorder for which the application of anesthesia is critical, due to muscle weakness, and cardiac and pulmonary involvement. Successful application of spinal anesthesia in a 2-year-old boy with DMD undergoing bilateral inguinal hernia repair is described in the present report. It is proposed that spinal anesthesia is an effective alternative to general anesthesia in certain pediatric patients, including those with DMD, for whom general anesthesia poses increased risk.

Administration of paracetamol versus dipyrone by intravenous patient-controlled analgesia for postoperative pain relief in children after tonsillectomy / Administração de paracetamol versus dipirona em analgesia controlada pelo paciente por via intravenosa para alívio da dor no pós-operatório de crianças após tonsilectomia

BACKGROUND AND OBJECTIVE: We compared the efficacy of intravenous (IV) paracetamol versus dipyrone via patient-controlled analgesia (PCA) for postoperative pain relief in children. METHODS: The study was composed of 120 children who had undergone elective tonsillectomy after receiving general anesthesia. Patients were divided into 3 groups according to the dosage of postoperative intravenous-patient-controlled analgesia: paracetamol, dipyrone, or placebo. Pain was evaluated using a 0- to 100-mm visual analog scale and 1- to 4-pain relief score at 30 min, 1, 2, 4, 6, 12, and 24 h postoperatively. Pethidine (0.25 mg kg-1) was administered intravenously to patients requiring rescue analgesia. Pethidine requirements were recorded during the first 24 h postoperatively, and treatment related adverse effects were noted. RESULTS: Postoperative visual analog scale scores were significantly lower with paracetamol group compared with placebo group at 6 h (p < 0.05), dipyrone group compared with placebo group at 30 min and 6 h (p < 0.05). No significant differences regarding visual analog scale values at 1, 2, 4, 12, and 24 h were found. No significant differences were found between groups with respect to pain relief score (p > 0.05). Postoperative pethidine requirements were significantly lower with paracetamol and dipyrone groups compared with placebo group (62.5%, 68.4% vs 90%, p < 0.05). No significant differences were found between groups with respect to nausea, vomiting and the any other adverse effects of the drugs (p > 0.05). CONCLUSIONS: Paracetamol and dipyrone have well tolerability profile and effective analgesic properties when administered IV-PCA for postoperative analgesia in children after tonsillectomy.

The management of non-melanocytic skin malignancies of the scalp and calvarium.

BACKGROUND: The management of advanced cutaneous malignancies has been controversial. Thirteen patients with nonmelanoma skin neoplasias that had invaded the bone of the calvarium and scalp were treated in our centre. OBJECTIVE: The purpose of this study was to evaluate our experience in treating these malignancies with scalp resection and full or partial thickness cranium reconstruction. PATIENTS AND METHODS: From June 2008 to March 2012, thirteen patients with locally advanced tumours of the scalp invading the calvarium were treated with wide local excision of the scalp combined with an underlying craniectomy and dural resection if needed. RESULTS: Using histopathological diagnosis eleven patients were diagnosed with basal cell carcinoma and two patients with squamous cell carcinoma. A full thickness cranium resection was performed in seven patients and partial in six patients. CONCLUSION: These large cancers occasionally invade adjacent structures, as well as bone, presenting a challenging surgical problem. In general, giant rotational or island scalp flaps and free tissue transfers are needed to close the area. Finding clean margins are an important part of treating patients with bone involvement and can usually be attained using outer tabula curettage thus preventing unnecessary morbidity.

[Efficacy of intravenous dexketoprofen trometamol compared to intravenous paracetamol for postoperative pain management after day-case operative hysteroscopy: randomized, double-blind, placebo-controlled study]. / Günübirlik operatif histeroskopi sonrasi intravenöz parasetamol ve deksketoprofen trometamol'ün analjezik etkinliklerinin karsilastirilmasi: randomize, çift kör, plasebo kontrollü çalisma.

OBJECTIVE: Adequate pain management following day-case surgery allows early ambulation of patients. In this study, we aimed to compare postoperative analgesic efficacy of intravenous (iv) dexketoprofen vs. iv paracetamol following day-case operative hysteroscopy. METHODS: One hundred and fourteen American Society of Anesthesiologists (ASA) I-II patients scheduled for day-case operative hysteroscopy were recruited and randomized to three groups in the study. Group D received 50 mg iv dexketoprofen trometamol, Group P 1000 mg iv paracetamol and Group C normal saline solution. Visual Analogue Scale (VAS) pain intensity, pain relief, sedation, nausea-vomiting, other side effects, and additional opioid analgesic requirement were noted at postoperative 15 minutes (min), 30 min, 1 hour (h), 2 h, and 3 h. Patients with VAS>=40 mm received meperidine 0.25 mg/kg as rescue analgesic medication. RESULTS: VAS scores at 15 min, 30 min, 1 h, and 2 h were significantly lower in Group D compared to Group C. VAS scores at 15 min and 30 min were significantly lower in Group D compared to Group P. The percentages of patients who required opioid treatment were 34%, 60%, and 63% in Groups D, P and C, respectively (p<0.05). Total delivered opioid dose was 0.10±0.16 mg/kg, 027±0.33 mg/kg and 0.28±0.25 mg/kg in Groups D, P and C, respectively (p<0.05). Pain relief score was significantly better in Group D at postoperative 15 min when compared with Group C (p<0.05). CONCLUSION: Our study demonstrated that iv dexketoprofen has superior efficacy for postoperative pain management following day-case operative hysteroscopy when compared with paracetamol and placebo.

The efficacy of intravenous paracetamol versus dipyrone for postoperative analgesia after day-case lower abdominal surgery in children with spinal anesthesia: a prospective randomized double-blind placebo-controlled study.

BACKGROUND: A multimodal and preventative approach to providing postoperative analgesia is becoming increasingly popular for children and adults, with the aim of reducing reliance on opioids. We conducted a prospective, randomized double-blind study to compare the analgesic efficacy of intravenous paracetamol and dipyrone in the early postoperative period in school-age children undergoing lower abdominal surgery with spinal anesthesia. METHODS: Sixty children scheduled for elective lower abdominal surgery under spinal anesthesia were randomized to receive either intravenous paracetamol 15 mg/kg, dipyrone 15 mg/kg or isotonic saline. The primary outcome measure was pain at rest, assessed by means of a visual analog scale 15 min, 30 min, 1 h, 2 h, 4 h and 6 h after surgery. If needed, pethidine 0.25 mg/kg was used as the rescue analgesic. Time to first administration of rescue analgesic, cumulative pethidine requirements, adverse effects and complications were also recorded. RESULTS: There were no significant differences in age, sex, weight, height or duration of surgery between the groups. Pain scores were significantly lower in the paracetamol group at 1 h (P = 0.030) and dipyrone group at 2 h (P = 0.010) when compared with placebo. The proportion of patients requiring rescue analgesia was significantly lower in the paracetamol and dipyrone groups than the placebo group (vs. paracetamol P = 0.037; vs. dipyrone P = 0.020). Time to first analgesic requirement appeared shorter in the placebo group but this difference was not statistically significant, nor were there significant differences in pethidine requirements, adverse effects or complications. CONCLUSION: After lower abdominal surgery conducted under spinal anesthesia in children, intravenous paracetamol appears to have similar analgesic properties to intravenous dipyrone, suggesting that it can be used as an alternative in the early postoperative period.

Intravenous paracetamol and dipyrone for postoperative analgesia after day-case tonsillectomy in children: a prospective, randomized, double blind, placebo controlled study.

UNLABELLED: Tonsillectomy is associated with severe postoperative pain for which, several drugs are employed for management. OBJECTIVE: In this double-blind, placebo-controlled study we aimed to evaluate the efficacy of intravenous paracetamol and dipyrone when used for post-tonsillectomy analgesia in children. METHOD: 120 children aged 3-6 yr, undergoing tonsillectomy with or without adenoidectomy and/or ventilation tube insertion were randomized to receive intraoperative infusions of paracetamol (15 mg/kg), dipyrone (15 mg/kg) or placebo (0.9% NaCl). Evaluation was carried out at 0.25, 0.50, 1, 2, 4, 6h postoperatively. Pethidine 0.25 mg/kg was utilized as rescue analgesic. Cumulative pethidine requirement was the primary outcome. Pain intensity measurement, pain relief, sedation level, nausea and vomiting, postoperative bleeding and any other adverse effects were noted. RESULTS: No significant difference was found in pethidine requirement between paracetamol and dipyrone groups. Cumulative pethidine requirement was significantly less in paracetamol and dipyrone groups vs. placebo. No significant difference was observed between groups in postoperative pain intensity scores throughout the study. CONCLUSION: Intravenous paracetamol is found to have a similar analgesic efficacy as intravenous dipyrone and they both help to reduce the opioid requirement for postoperative analgesia in pediatric day-case tonsillectomy.

O manejo da dor pós-amigdelectomia pode ser feito com uma série de medicamentos. OBJETIVO: O presente estudo duplo-cego placebo controlado pretendeu avaliar a eficácia de paracetamol e dipirona administrados por via endovenosa na analgesia de pacientes pediátricos pós-amigdelectomia. MÉTODO: Cento e vinte crianças com idades entre três e seis anos submetidas à amigdelectomia com ou sem adenoidectomia e/ou entubação foram randomizadas para receber infusões de paracetamol (15 mg/kg), dipirona (15 mg/kg) ou placebo (0,9% NaCl) durante a cirurgia. As avaliações foram executadas com 0,25, 0,50, 1, 2, 4, 6h de pós-operatório. Petidina 0,25 mg/kg foi utilizada como analgésico de resgate. Dose acumulada de petidina foi o desfecho primário. Medições de intensidade da dor, alívio da dor, nível de sedação, náusea e vômitos, hemorragia no pós-operatório e outros efeitos adversos foram anotados. RESULTADOS: Nenhuma diferença significativa foi encontrada na dose acumulada de petidina entre os grupos paracetamol e dipirona. A dose acumulada de petidina foi significativamente menor nos grupos paracetamol e dipirona em comparação ao grupo placebo. Nenhuma diferença significativa foi observada entre os escores de dor no pós-operatório dos grupos durante o estudo. CONCLUSÃO: Paracetamol endovenoso tem eficácia analgésica semelhante à da dipirona endovenosa; ambos ajudam a reduzir a necessidade de opioides na analgesia pós-operatória de pacientes pediátricos submetidos à amigdelectomia em hospital-dia.
