Impact of vaginal delivery history on anesthesia management of hysteroscopic surgery under intravenous general anesthesia: a cohort study of 99 patients / 南方医科大学学报

OBJECTIVE@#To evaluate the impact of a history of vaginal delivery on anesthesia management of patients undergoing hysteroscopic surgery under intravenous general anesthesia without tracheal intubation.@*METHODS@#Ninety-nine patients undergoing hysteroscopic surgery under intravenous general anesthesia were enrolled in this study, including 43 patients with (VD group) and 56 patients without a history of vaginal delivery (NVD group). For all the patients, blood pressure, heart rate (HR), blood oxygen saturation (SpO2) and bispectral index (BIS) were recorded before anesthesia (T1), after anesthesia (T2), after cervical dilation (T3), and at 3 min after cervical dilation (T4). Propofol and etomidate doses during anesthesia induction, the total dose of propofol administered, additional intraoperative bolus dose and times of propofol, intraoperative body movement, total operation time and surgeons' satisfaction feedback scores were compared between the two groups. The postoperative awake time, recovery time, VAS score at 30 min after operation, and postoperative nausea and vomiting (PONV) were also compared.@*RESULTS@#There was no significant differences in SBP, DBP, HR, SpO2, or BIS between the two groups at T1 and T2, but at T3 and T4, SBP and DBP were significantly higher in NVD group than in VD group (P < 0.01); HR was significantly higher in NVD group only at T3 (P < 0.01). The application of vasoactive drugs did not differ significantly between the two groups. The total dose of propofol, additional intraoperative dose and times of propofol were all greater in NVD group than in VD group (P < 0.01). More body movements of the patients were observed in NVD group (P < 0.01), which also had lower surgeons' satisfaction score for anesthesia (P < 0.01), higher postoperative VAS score (P < 0.05), and shorter postoperative awake time (P < 0.05) and recovery time (P < 0.01).@*CONCLUSION@#A history of vaginal delivery has a significant impact on anesthesia management of patients undergoing hysteroscopic surgery under intravenous general anesthesia without tracheal intubation in terms of hemodynamic changes, anesthetic medication, and postoperative recovery quality, suggesting the necessity of individualized anesthesia management for these patients.

Exploratory study of tracheal extubation in operating room after single-lung transplantation / 器官移植

Objective To evaluate the feasibility and safety of tracheal extubation in operating room for patients with end-stage chronic obstructive pulmonary disease (COPD) after single-lung transplantation. Methods Clinical data of 57 recipients who underwent single-lung transplantation due to end-stage COPD were retrospectively analyzed. According to the evaluation indexes of tracheal extubation in operating room established by our hospital, 17 recipients eligible for tracheal extubation in operating room were assigned into the operating room extubation group (OR extubation group) and 40 recipients receiving tracheal extubation in intensive care unit (ICU) were allocated in the ICU extubation group. The evaluation results of intraoperative tracheal extubation and postoperative recovery were compared between two groups. Results Compared with the ICU extubation group, recipients in the OR extubation group had higher oxygenation index, lower arterial partial pressure of carbon dioxide (PaCO2), lower blood lactic acid level, less fluctuation range of blood pressure and fewer cases receiving extracorporeal membrane oxygenation (ECMO) during operation (all P < 0.05). Two recipients in the OR extubation group received repeated tracheal intubation at 6 and 8 h after returning to ICU, and tracheal extubation at postoperative 6 and 9 d. In the OR extubation group, time of postoperative mechanical ventilation, length of postoperative ICU and hospital stay of the recipients were shorter than those in the ICU extubation group (all P < 0.05). The incidence of grade 3 primary graft dysfunction (PGD), atrial tachyarrhythmia, continuous renal replacement therapy and 1-year survival rate did not significantly differ between two groups (all P > 0.05). Conclusions The tracheal extubation regimen in the operating room for COPD patients after single-lung transplantation established by our hospital is safe and feasible, which shortens the time of postoperative mechanical ventilation, the length of postoperative ICU and hospital stay, whereas does not increase the incidence of postoperative complications.

Value of pressure-strain loop in evaluating the effects of thoracic paravertebral block on left ventricular function before off-pump coronary artery bypass graft / 中华超声影像学杂志

Objective:To observe the effects of bilateral thoracic paravertebral block (TPVB) on left ventricular myocardial work using pressure-strain loop(PSL) in patients before off-pump coronary artery bypass graft(OPCABG).Methods:A total of 24 patients with coronary heart disease undergoing selective OPCABG were recruited in the First Affiliated Hospital of Nanjing Medical University from May to August 2021. All patients underwent ultrasound-guided TPVB preoperatively. Left ventricular global work, including global longitudinal strain(GLS), global work index(GWI), global constructive work(GCW), global waste work(GWW), global work efficiency(GWE), and regional work, including myocardial work index(MWI), myocardial work efficiency(MWE) were observed before TPVB and 20 minutes after TPVB.Results:The parameters of heart rate and left ventricular outflow tract blood flow were decreased [(69.13±10.72)bpm vs (65.46±9.66)bpm, P=0.010; (13.86±2.83)ml vs (12.72±2.60)ml, P=0.017]. The MWI in regional segments of hypokinesis and akinesis were significantly improved [hypokinesis: (1 175.76±206.64)mmHg% vs (1 349.38±462.35)mmHg%, P=0.004; akinesis: (684.94±251.39)mmHg% vs (965.35±384.33)mmHg%, P=0.001] and the MWE in regional segments of hypokinesis and akinesis were improved [hypokinesis: (87.79±7.46)% vs (90.35±6.39)%, P=0.029; akinesis: (70.24±18.03)% vs (80.15±16.65)%, P=0.021]. There were no significant changes in MWI, MWE, LVEF, GLS, GWI, GCW, GWW and GWE(all P>0.05). Conclusions:Based on PSL, the changes of left ventricular work in patients with OPCABG before and after TPVB show that TPVB can improve the blood supply of the ischemic myocardium, which provides a reliable basis for optimizing the perioperative anesthesia management.

Use of sugammadex in acute intermittent porphyria / Uso de sugammadex en la porfiria aguda intermitente

Abstract: Porphyrias are a group of rare diseases, which include acute intermittent porphyria. It is essential for the anesthesiologist to identify acute porphyrias and to recognize a porphyric crises. These can be triggered by several factors, which can be present throughout the perioperative period. A 70-year-old male, ASA III, with a personal history of acute intermittent porphyria and ischemic heart disease, scheduled for laparoscopic sigmoidectomy. Prolonged fasting, dehydration and potentially porphyrinogenic drugs were avoided. General anesthesia was induced with fentanyl, lidocaine, propofol and rocuronium and maintained with desflurane. The decision to reverse the neuromuscular blockade with sugammadex was considered due to the benefits over risks of this drug when compared to neostigmine (associated with atropine) and the description of its use without harm in two cases of variegate porphyria. The following paper emphasize the importance of careful anesthetic management throughout the perioperative period and describe a case of successful reversal of neuromuscular block with sugammadex, highlighting this case as the first case reported of its use in acute intermittent porphyria.

Resumen: Las porfirias son un grupo de enfermedades raras, entre las que se encuentra la porfiria aguda intermitente. Es fundamental que el anestesista identifique las porfirias agudas y reconozca una crisis porfírica. Éstos pueden ser desencadenados por varios factores, que pueden estar presentes durante todo el periodo perioperatorio. Varón de 70 años, ASA III, con antecedentes personales de porfiria aguda intermitente y cardiopatía isquémica, programado para sigmoidectomía laparoscópica. Se evitó el ayuno prolongado, la deshidratación y los fármacos potencialmente porfirinógenos. La anestesia general se indujo con fentanilo, lidocaína, propofol y rocuronio y se mantuvo con desflurano. La decisión de revertir el bloqueo neuromuscular con sugammadex se consideró debido a los beneficios sobre los riesgos de este fármaco en comparación con la neostigmina (asociada con la atropina) y a la descripción de su uso sin daños en dos casos de porfiria variegada. El siguiente artículo enfatiza la importancia de un manejo anestésico cuidadoso durante todo el periodo perioperatorio y describe un caso de reversión exitosa del bloqueo neuromuscular con sugammadex, destacando este caso como el primero reportado de su uso en porfiria aguda intermitente.

Anesthesia management for resection of adrenal cortical carcinoma in children / 中华麻醉学杂志

The medical records of 11 pediatric patients undergoing resection of adrenal cortical carcinoma from January 2012 to January 2019 in our hospital were collected.Anesthesia management for resection of adrenal cortical carcinoma in children was analyzed and investigated.Anesthesia was induced by intravenously injecting atropine 0.01 mg/kg, dexamethasone 2-5 mg, propofol 2-3 mg/kg, sufentanil 0.3-0.5 μg/kg or fentanyl 1-2 μg/kg, rocuronium 0.5 mg/kg or cis-atracurium 0.1-0.2 mg/kg.Radial artery catheterization and femoral vein catheterization were performed under ultrasound guidance.Arterial blood pressure was continuously monitored.The esophageal thermometers probe was placed to continuously monitor body temperature.The catheter was placed to monitor urine volume.Intermittent positive pressure ventilation was performed after endotracheal intubation with the inspiratory oxygen fraction set 60%-100%, oxygen flow rate 2-3 L/min, tidal volume 7-10 ml/kg, ventilation frequency 20-26 times/min, inhalation/respiration ratio 1∶(1.5-2.0) and airway pressure 16-20 cmH 2O, and the end-tidal pressure of carbon dioxide was maintained at 35-45 mmHg.Anesthesia was maintained by inhaling 2%-4% sevoflurane and/or intravenously infusing propofol 0.10-0.15 mg·kg -1·min -1, and continuously infusing remifentanil 0.2-0.5 μg·kg -1·min -1.Hemodynamics was maintained within the normal range, and the bispectral index was maintained at 40-60 during the surgery.Before the tumor was completely removed, 5-10 mg/kg sodium hydrocortisone succinate was intravenously infused.At the end of the operation, sufentanil 0.75-1.00 μg·kg -1·d -1 or fentanyl 7.5-10.0 μg·kg -1·d -1 was continuously infused for postoperative analgesia until 48 h after operation.Operation was smoothly completed with stable anesthesia in all the pediatric patients.The tracheal tube was removed successfully after the operation.All children in this group were discharged from hospital and no death occurred.Anesthesia management for resection of adrenal cortical carcinoma required an appreciation of the clinical characteristics and perioperative pathophysiological changes.Paying attention to the changes in hormone levels during perioperative period and timely adjusting the children′s internal environment to maintain the stability of anesthesia and reduce the stress response were the keys to anesthesia management.

Different anesthesia management in preterm infants undergoing surgeries for retinopathy of prematurity: A retrospective study / 北京大学学报(医学版)

OBJECTIVE@#To evaluate the effect of different anesthesia management on clinical outcomes in former prematurely born infants undergoing surgeries for retinopathy of prematurity (ROP).@*METHODS@#In this retrospective study, electronic medical record database was searched for all former prematurely born infants (gestational age < 37 weeks and post conceptual age < 60 weeks) who received ROP surgery under inhalational general anesthesia between November 2016 and October 2018. The patients were divided into two groups based on anesthesia management: laryngeal mask airway (LMA) insertion without intravenous muscle relaxant injection and with pressure support ventilation (LMA group) or airway secured with endotracheal tube (ETT) with intravenous muscle relaxant injection and pressure controlled ventilation (ETT group). Primary outcomes included perioperative adverse events and complications. Extubation time and length of stay after surgery were also recorded.@*RESULTS@#Sixty eight preterm infants in the LMA group and 100 preterm infants in the ETT group were included. The incidence of adverse events during surgery (including airway management change and desaturation) was similar in LMA group and ETT group (4.4% vs. 1.0%, P =0.364). During the early recovery period after surgery, the incidence of difficult extubation (extubation time >30 min) was significantly lower in LMA group compared with ETT group (4.4% vs.15.0%, RR=0.262, 95%CI:0.073－0.942, P=0.029). The incidence of respiratory events was similar between the two groups (20.6% vs. 27.0%, P =0.342). However, the incidence of apnea was significantly lower in the LMA group than in the ETT group (5.9% vs.19.0%, RR=0.266, 95%CI: 0.086－0.822, P =0.015). No significant difference was observed between the LMA group and ETT group in incidences of cardiovascular events (0% vs. 1.0%, P =1.000) and unplanned admission to neonatal intensive care unit (5.9% vs. 7.0%, P=0.774). No airway spasm, re-intubation, aspiration or regurgitation was observed during early recovery. During late recovery after returning to ward, the incidence of adverse events was also similar between the two groups (0% vs. 2.0%, P =0.241). The median (IQR) extubation time was 6 (5, 10) min in LMA group and 10 (6, 19) min in ETT group (P < 0.001). The median length of stay after surgery was significantly shortened in LMA group compared with ETT group [20 (17, 22) hours vs. 22 (17, 68) hours, P =0.002].@*CONCLUSION@#Compared with endotracheal intubation with intravenous muscle relaxant injection, laryngeal mask airway insertion without muscle relaxant could achieve an early extubation, and reduce the incidence of apnea during early recovery period in former prematurely born infants undergoing ROP surgery.

To keep pace with the developing technologies in this field it is imperative for the cardiac anesthesiologists to have aworking knowledge of these systems, recognize potential complications and formulate an anesthetic plan to provide safe patient care. Challenges posed by the use of robotic systems include, long surgical times, problems with one lung anesthesia in presence of coronary artery disease, minimally invasive percutaneous cardiopulmonary bypass management and expertise in Trans-Esophageal Echocardiography. A long list of cardiac surgeries are performed with the use of robotic assistance, and the list is continuously growing as surgical innovation crosses new boundaries. Current research in robotic cardiac surgery like beating heart off pump intracardic repair, prototype epicardial crawling device, robotic fetal techniques etc. are in the stage of animal experimentation, but holds a lot of promise in future.

Anesthetic Management of the Patient with Paraneoplastic Pemphigus: A case report / 대한마취과학회지

Paraneoplastic pemphigus is a distinct and rare autoimmune disease characterized by extensive and painful mucosal ulcerations and polymorphic desquamated skin lesions in the setting of an underlying neoplasm, typically of lymphoreticular origin. Thus difficulties in the management of anesthesia can be expected. A 66-years-old man was scheduled for removal of intraabdominal sarcoma associated with paraneoplastic pemphigus. Physical examination showed multiple erythematous bullae, crusts, plaques and target-like lesions on the whole body and desquamated erythematous skin lesions on the back and extremities. In the operating room, his right femoral artery was cannulated with a 20 G, 12.7 cm CVP catheter and left femoral and subclavian veins with 14 G, 20 cm CVP catheters, respectively. After application of 4 % lidocaine spray, his oropharynx and supraglottic area were evaluated under direct laryngoscopy and revealed multiple ulcerations on oral mucosa, but no distinct lesion on supraglottic area. Anesthesia was induced by rapid-sequence method with fentanyl, thiopental sodium and succinylcholine followed by endotracheal intubation. The endotracheal tube was held by a roll gauze around the neck and its cuff was minimally inflated to avoid overpressure against his tracheal wall. After the end of surgery, his oral cavity was suctioned with no remarkable bleeding, and tracheal wall including cuff-contacted area was evaluated under fiberoptic bronchoscopy, revealed intact wall without any bulla or ulceration. The patient was transferred to intensive care unit for proper postoperative management after extubation of endotracheal tube.
