Continuous Spinal Anesthesia for Labor Analgesia and Cesarean Delivery in a Parturient With Familial Dilated Cardiomyopathy: A Case Report.

We report a case of successful continuous spinal anesthesia (CSA) for labor analgesia and cesarean delivery in a patient with familial dilated cardiomyopathy (DCM). A 33-year-old pregnant woman diagnosed with DCM was scheduled for a vaginal delivery under labor analgesia. An accidental intrathecal catheter was placed, and labor analgesia was provided by CSA. The vaginal delivery was converted to a cesarean delivery, and an intrathecal catheter was used for transition, which avoided hemodynamic changes and allowed the patient to safely undergo cesarean delivery. CSA is a reliable and rapidly titratable technique that provides excellent analgesia without hemodynamic changes in patients with DCM undergoing labor analgesia and subsequent cesarean delivery.

Spinal Anesthesia in Hemodynamic Instability: A Case Report.

Anesthetic dilemmas are not rare in daily practice. Frequently, patients present with comorbid conditions that make general anesthesia risky (e.g., difficult airway and severe pulmonary dysfunction) and contraindications to neuraxial anesthesia at the same time. Reports on the successful anesthetic management of these patients can provide useful information. We report a case of a patient with severe hemodynamic instability who underwent spinal anesthesia for surgical hip debridement. General anesthesia and airway manipulation were avoided because the patient had recently recovered from SARS-CoV-2 pneumonia amid the first wave of the coronavirus disease 2019 (COVID-19) pandemic when very little was known about the disease and no ventilators were available for postoperative care. We explain in detail the continuous spinal anesthesia technique using a conventional epidural catheter and prophylactic norepinephrine when cardiovascular instability was the major concern.

Cesarean Delivery in a Patient With Body Mass Index Over 100: Continuous Spinal Anesthesia in Two Consecutive Deliveries.

Anesthetic implications for morbidly obese parturients have been well described; however, the literature has not yet clarified whether there are additional or unique concerns if the body mass index (BMI) rises farther above the so-called super morbid obesity level: BMI >50 kg/m2. There have only been a few case reports focusing on patients with BMI close to or above 100. Parturients with BMI significantly greater than 50 are uncommon, but they represent an increasing proportion among the morbidly obese. In this report, we present the use of continuous spinal anesthesia in consecutive cesarean deliveries for a patient with a BMI of 102 at her first delivery and 116 at her second. For both deliveries, an intrathecal catheter dosing incrementally provided effective anesthesia with a cumulative dose of hyperbaric bupivacaine 12 mg, fentanyl 15 mcg, and morphine 100 mcg given in 0.25-ml increments over 12 minutes, with 0.25-ml sterile saline flushes between doses. While dosing the catheter, the patient was gradually lowered to a 30° semi-recumbent position for surgery. This strategy minimized the risk of high spinal block or respiratory distress. She did not develop any postdural puncture headache (PDPH). This case report offers an extreme example and provides estimates towards adjusting staffing, equipment, location, timing, positioning, anesthetic technique, and dosing for cesarean deliveries in patients with very high BMI levels.

Intrathecal catheter for severe low back pain during deep brain stimulation placement: illustrative case.

BACKGROUND: Deep brain stimulation (DBS) is a U.S. Food and Drug Administration-approved therapy for medically refractory Parkinson's disease, essential tremor, and other neurological conditions. The procedure requires prolonged immobility and can result in significant patient discomfort, potentially limiting patient selection. In addition, surgical requirements necessitate avoidance of medications that may alter or suppress the patient's arousal or baseline tremor during macrostimulation testing. OBSERVATIONS: In this study, the authors describe the use of continuous spinal anesthesia with local anesthetic to manage a patient with severe back pain who was intolerant of semisupine position during stereotactic computed tomography and stage 1 of DBS placement. LESSONS: Continuous spinal anesthesia is an effective strategy to manage patients with severe back pain undergoing DBS surgery for upper extremity motor symptoms.

Laparoscopic cholecystectomy under continuous spinal anesthesia in a patient with Steinert's disease / Colecistectomia laparoscópica sob raquianestesia contínua em paciente com doença de Steinert

ABSTRACT Steinert's disease is an intrinsic disorder of the muscle with multisystem manifestations. Myotonia may affect any muscle group, is elicited by several factors and drugs used in general anesthesia like hypnotics, sedatives and opioids. Although some authors recommend the use of regional anesthesia or combined anesthesia with low doses of opioids, the safest anesthetic technique still has to be established. We performed a continuous spinal anesthesia in a patient with Steinert's disease undergoing laparoscopic cholecystectomy using 10 mg of bupivacaine 0.5% and provided ventilatory support in the perioperative period. Continuous spinal anesthesia was safely used in Steinert's disease patients but is not described for laparoscopic cholecystectomy. We reported a continuous spinal anesthesia as an appropriate technique for laparoscopic cholecystectomy and particularly valuable in Steinert's disease patients.

RESUMO A doença de Steinert é uma desordem intrínseca do músculo com manifestações multissistêmicas. A miotonia pode afetar qualquer grupo muscular e é provocada por vários fatores e medicamentos usados em anestesia geral, como hipnóticos, sedativos e opiáceos. Embora alguns autores recomendem o uso de anestesia regional ou anestesia combinada com opiáceos em doses baixas, a técnica anestésica mais segura ainda precisa ser estabelecida. Administramos raquianestesia contínua em um paciente com doença de Steinert submetido à colecistectomia laparoscópica, com 10 mg de bupivacaína a 0,5%, e fornecemos suporte ventilatório no período perioperatório. A raquianestesia contínua foi usada com segurança em pacientes com doença de Steinert, mas não foi relatada em colecistectomia laparoscópica. Relatamos a raquianestesia contínua como uma técnica adequada para a colecistectomia laparoscópica e particularmente valiosa em pacientes com doença de Steinert.

Is there a difference in postdural puncture headache after continuous spinal anesthesia with 28G microcatheters compared with punctures with 22G Quincke or Sprotte spinal needles?

In this retrospective study, the question was raised and answered whether the rate of postdural puncture headache (PDPH) after continuous spinal anesthesia with a 28G microcatheter varies using a Quincke or a Sprotte needle. The medical records of all patients with allogenic joint replacement of the knee or hip or arthroscopic surgery of the knee joint undergoing continuous spinal anesthesia with a 22G Quincke (n=1,212) or 22G Sprotte needle (n=377) and a 28G microcatheter during the past 6 years were reviewed. We obtained the approval of the ethical committee. The rates of PDPH were statistically not different between both groups: 1.5% of patients developed PDPH after dura puncture with a Quincke needle and 2.1% with a Sprotte needle in women and men.

The comparison of levobupivacaine in continuous or single dose spinal anesthesia for transurethral resection of prostate surgery.

BACKGROUND: The aim of the study is to compare the efficacy of levobupivacaine induced continuous spinal anesthesia (CSA) versus single dose spinal anesthesia (SDSA) in patients who are planned to undergo transurethral prostate resection. METHODS: Sixty years or older, ASA I-II or III, 50 patients were included in the study. 12.5mg 0.5% levobupivacaine were administered intrathecally in SDSA group. In CSA group, initially 2mL of 0.25% levobupivacaine were administered through spinal catheter. In order to achieve sensory block level at T10 dermatome, additional 1mL of 0.25% levobupivacaine were administered through the catheter in every 10min. Hemodynamic parameters and block characteristics were recorded. Preoperative and postoperative blood samples of the patients were drawn to determine plasma cortisone and plasma epinephrine levels. RESULTS: CSA technique provided better hemodynamic stability compared to SDSA technique particularly 90min after intrathecal administration. The rise in sensory block level was rapid and the time to reach surgical anesthesia was shorter in SDSA group. Motor block developed faster in SDSA group. In CSA group, similar anesthesia level was achieved by using lower levobupivacaine dose and which was related to faster recovery. Although, both techniques were effective in preventing surgical stress respond, postoperative cortisone levels were suppressed more in SDSA group. CONCLUSION: CSA technique with 0.25% levobupivacaine can be used as a regional anesthesia method for elderly patients planned to have TUR-P operation.

Comparação de levobupivacaína em raquianestesia contínua ou com dose única para cirurgia de ressecção transuretral de próstata / The comparison of levobupivacaine in continuous or single dose spinal anesthesia for transurethral resection of prostate surgery / Comparación de la levobupivacaína en raquianestesia continua ocon dosis única para cirugía de resección transuretral de próstata

Justificativa e objetivo: comparar a eficácia de levobupivacaína na indução de raquianestesia contínua (RAC) versus dose única (Radu) em pacientes programados para ressecção transuretral de próstata (RTUP). Métodos: foram incluídos no estudo 50 pacientes, ≥ 60 anos, ASA I-II ou III. Levobupivacaína a 0,5% (12,5 mg) foi administrada por via intratecal no grupo Radu. No grupo RAC, levobupivacaína a 0,25% (2 mL) foi inicialmente administrada através de cateter espinhal. Para o nível de bloqueio sensorial atingir o dermátomo T10, 1 mL adicional de levobupivacaína a 0,25% foi administrado através do cateter a cada 10 minutos. Os parâmetros hemodinâmicos e as características do bloqueio foram registrados. Amostras de sangue dos pacientes foram coletadas nos períodos pré- e pós-operatórios para determinar os níveis plasmáticos de cortisona e adrenalina. Resultados: a RAC proporcionou melhor estabilidade hemodinâmica em comparação com a Radu, particularmente aos 90 minutos após a administração intratecal. O aumento do nível de bloqueio sensorial foi rápido e o tempo para atingir a anestesia cirúrgica foi menor no grupo Radu. O desenvolvimento do bloqueio motor foi mais rápido no grupo Radu. No grupo RAC, um nível semelhante de anestesia foi obtido com o uso de uma dose mais baixa de levobupivacaína, que foi relacionada à recuperação mais rápida. Embora ambas as técnicas tenham sido eficazes na prevenção da resposta ao estresse cirúrgico, os níveis de cortisona no pós-operatório foram mais suprimidos no grupo Radu. Conclusão: a técnica RAC com levobupivacaína a 0,25% pode ser usada como um método de anestesia regional em pacientes idosos programados para RTUP. .

Continuous spinal anesthesia for lower limb surgery: a retrospective analysis of 1212 cases.

BACKGROUND: Continuous spinal anesthesia is a very reliable and versatile technique for providing effective anesthesia and analgesia. However, the incidence of possible complications, including postdural puncture headache or neurological impairment, remains controversial. Therefore, the aim of the present retrospective study was to analyze a large number of patients for the incidence of adverse events after continuous spinal anesthesia with a microcatheter. METHODS: This retrospective study was conducted on 1212 patients who underwent surgery of the lower extremities with continuous spinal anesthesia, which was administered with 22-gauge Quincke spinal needles and 28-gauge microcatheters. Sociodemographic and clinical data were available from the patient records, and data on headaches and patient satisfaction were drawn from a brief postoperative patient questionnaire. RESULTS: The patient population included 825 females (68%) and 387 males; the median age was 61 (56-76). The types of operations performed were 843 hip prostheses, 264 knee prostheses, and 105 other leg operations. No major complications were observed in any of these patients. Tension headaches were experienced by 190 (15.7%) patients, but postdural puncture headaches were reported by only 18 (1.5%) patients. Nearly all patients (98.4%) were satisfied with continuous spinal anesthesia and confirmed that they would choose this kind of anesthesia again. CONCLUSION: Based on the findings of this large data analysis, continuous spinal anesthesia using a 28-gauge microcatheter appears to be a safe and appropriate anesthetic technique in lower leg surgery for aged patients.

Continuous spinal anesthesia with epidural catheters: An experience in the periphery.

BACKGROUND AND AIM: Continuous spinal anesthesia (CSA) offers considerable advantages over "singleshot" spinal or epidural anesthesia since it allows administration of well-controlled anesthesia using small doses of local anesthetics and a definite end point with less failure rate. There are described technical difficulties with introduction of spinal micro catheters and hence this study was undertaken by using epidural catheters. MATERIALS AND METHODS: Sixty patients of ASA grade II to III were selected and they were administered continuous spinal anesthesia with Portex 18-G epidural catheters. RESULTS: The introduction was done in first attempt and was easy in all cases. The intraoperative period was uneventful in all cases. Early postoperative analgesia was achieved in all cases. Only two patients (3%) had postdural puncture headache controlled with simple analgesics. In a 3 month postoperative followup, the incidence of neurological complication is nil. CONCLUSION: We conclude CSA with epidural catheters is a simple and safe alternative for prolonged procedures with negligible failure rate especially in high-risk patients and in patients with possible difficulties in administration of general anesthesia.

Continuous spinal anesthesia for renal homotransplantation / 国际外科学杂志

Objective To discuss the feasibility and safety of continuous spinal anesthesia (CSA) in renal transplantation through comparing the effects of combined spinal and epidural anesthesia (CSEA) and CSA renal transplantation. Methods Sixty patients undertaking renal transplantation were divided into two groups randomly. Group A, 30 patients, undertaking operation with CSEA; Group B, 30 patients, undertaking operation with CSA. The patients in group A were injected 2 mL 0.75% ropivacaine, then epidural catheter was inserted, 0. 75% ropivacaine 10 mL was administered when needed. The patients in group B were injected 2 mL 0.75% ropivacaine into spinal through Spinocath catheter, and 0.75% ropivacaine 1ml was administered through Spinocath catheter when needed. We observed the effects of the two anesthesia methods and the changes of the patients' vital signs. Results The patients in group A and B all completed the operation smoothly; there were no significant differences in the circulatory function before and during operation; there were no complications related to anesthesia in all the patients; group B was superior to group A in the aspects of the control and maintaining of anesthesia. Conclusion Continuous spinal anesthesia applied to renal transplantation is safe and feasible.

Anestesia espinal a través de catéter para cesárea en una mujer con estenosis valvular aórtica severa / Spinal anesthesia through catheter for cesarean section in a woman with severe aortic valve stenosis

.

It is the case of afatient 32years- oíd and 34 weeks of gestation with antecedents of severe aortic stenosis that is programmedfor caesarean section. She has been displaying progressive symptoms (dyspnea and síncope) reason why she had tried an aortic valvuloplasty with balloon without satisfactory result. The anesthesia for the procedure was spinal continuous through catheter using 3,75 mgs of 0.5% hyperbaric bupivacaina, 25 mcg of fentanyl and 100 mcg morphine, with invasive monitoring of arterial bloodfressure and cardiac output. Verioperative maternal orfetal complications did not appear. With this report and the revisión of literature, we suggest that the neuroaxial anesthetic techniques are agood alternative to the general anesthesia in fregnated patients with severe aortic valvular stenosis.
