RESUMEN
INTRODUCTION: Pregnancy in a woman with heart and chronic renal failure can lead to life-threatening complications for both mother and child. Although such cases are often delivered by cesarean section, few reports have described anesthesia methods. CASE PRESENTATION: We encountered a case in which cesarean section was performed using combined spinal and epidural anesthesia for a pregnant woman with chronic renal and heart failure. The 35-year-old Japanese woman had been undergoing hemodialysis for several years. Heart failure symptoms that appeared during pregnancy initially improved with treatments such as increasing hemodialysis, but recurred. She was admitted to the intensive care unit. The initial plan was to deliver the baby after a few weeks, but further progression of heart failure became a concern. After a clinical conference among staff, a cesarean section with combined spinal and epidural anesthesia was scheduled for 24 weeks, 0 days of gestation. The anticoagulant for dialysis was also changed from heparin to nafamostat in preparation for cesarean section. Monitoring was started with central venous and radial artery pressures before induction of anesthesia. Combined spinal and epidural anesthesia was induced and the cesarean section was completed without complications. Surgery was initiated under continuous administration of phenylephrine, which was intended to avoid hypotension due to anesthesia. The hemodynamic and respiratory status of the patient remained stable postoperatively. After the cesarean section, morphine was administered epidurally and the epidural catheter was removed. CONCLUSION: Cesarean section was safely performed for a pregnant woman with renal and heart failure using combined spinal and epidural anesthesia.

BACKGROUND: Respiratory functions may be impaired in cesarean section (C/S) delivery performed under spinal anesthesia (SA) and oxygen supplementation may be required. Therefore, we conducted a randomized controlled study aimed to evaluate the effects of different oxygen administrations in pregnant women on the lungs during C/S under SA using ultrasound and oxygen reserve index (ORI). METHODS: We conducted a randomized, controlled, single-center study from May 1, 2021, to March 31, 2022. A total of 90 patients scheduled for C/S under SA were randomly divided into 3 groups. Following the SA, patients in group 0 were treated with room air, in Group 3 were administered 3 L/min O2 with a nasal cannula (NC), in Group 6 were administered 6 L/min O2 with a simple face mask. In addition to routine monitoring, ORI values were measured. Lung aeration was evaluated through the modified lung ultrasound score (LUS) before the procedure (T0), at minute 0 (T1), 20 (T2), and hour 6 (T3) after the procedure, and ∆LUS values were recorded. RESULTS: After SA, the ORI values of Group 3 were higher than Group 0 at all times (p < 0.05), while the intraoperative 1st minute and the 10th, 25th and 40th minutes after delivery (p = 0.001, p = 0.027, p = 0.001, p = 0.019) was higher than Group 6. When the LUS values of each group were compared with the T0 values a decrease was observed in Group 3 and Group 6 (p < 0.001, p = 0.016). While ∆LUS values were always higher in Group 3 than in Group 0, they were higher only in T1 and T2 in Group 6. CONCLUSION: We determined that it would be appropriate to prefer 3 L/min supplemental oxygen therapy with NC in C/S to be performed under SA.

BACKGROUND: Postpartum urinary retention is a common complication following caesarean section, with significant implications for patient comfort and recovery. Combined spinal and epidural anaesthesia is frequently employed for caesarean section, but postpartum urinary retention remains a clinical concern despite its benefits. This study aimed to investigate the effectiveness of hydromorphone hydrochloride combined with bupivacaine for combined spinal and epidural anaesthesia in reducing postpartum urinary retention. METHODS: A retrospective analysis was conducted on patients who received combined spinal and epidural anaesthesia for caesarean section. The control group received bupivacaine, whereas the hydromorphone hydrochloride combined with bupivacaine spinal-epidural anaesthesia (HB) group received hydromorphone hydrochloride combined with bupivacaine. Data on demographics, anaesthesia, operative characteristics, postoperative urinary retention and adverse events were collected and analysed. RESULTS: The study enrolled 105 patients, with a control group (n = 51) receiving bupivacaine spinal-epidural anaesthesia and an observation group (n = 54) receiving hydromorphone hydrochloride combined with bupivacaine spinal-epidural anaesthesia. The incidence of postoperative urinary retention was significantly lower in the HB group than in the control group (3.70% vs. 17.65%, p = 0.044). Furthermore, the HB group exhibited a shorter time to first voiding after anaesthesia (5.72 ± 1.26 h vs. 6.28 ± 1.35 h, p = 0.029), lower peak postvoid residual volume (168.57 ± 25.09 mL vs. 180.43 ± 30.21 mL, p = 0.032), decreased need for postoperative catheterisation (5.56% vs. 21.57%, p = 0.034) and shorter duration of urinary catheterisation (10.92 ± 2.61 h vs. 12.04 ± 2.87 h, p = 0.039) than the control group. Correlation analysis supported a negative correlation between hydromorphone supplementation and parameters related to postoperative urinary retention. Multivariate regression analysis demonstrated a significant association between the duration of urinary catheterisation and the use of hydromorphone with the occurrence of postoperative urinary retention, providing further insights into the multifactorial nature of this postoperative complication. CONCLUSIONS: The addition of hydromorphone hydrochloride to bupivacaine for combined spinal and epidural anaesthesia was associated with a reduced incidence of postpartum urinary retention and improved postoperative voiding parameters, without significantly increasing the risk of adverse events.

RATIONALE: Dopa-responsive dystonia (DRD) is a rare autosomal dominant hereditary disorder with a prevalence of 0.5 per million population. The disease is characterized by onset of dystonia in childhood, progressive aggravation of the dystonia with diurnal fluctuation, and complete or near complete alleviation of symptoms with low-dose oral levodopa. The incidence of DRD is low, and only a few publications have described this disorder connected with anesthesia. PATIENT CONCERNS: We present a case involving a pregnant woman with DRD who continued levodopa/benserazide throughout the pregnancy. The perioperative anesthesia management was described. We used chloroprocaine 3% for epidural anesthesia during cesarean section. DIAGNOSES: Dopa-responsive dystonia. INTERVENTIONS: Levodopa/benserazide. OUTCOMES: In summary, levodopa/benserazide was continued throughout our patient's pregnancy with a good obstetric outcome, and chloroprocaine was safely used in epidural anesthesia without deterioration of her dystonic symptoms. LESSONS: Chloroprocaine was safely used in epidural anesthesia without deterioration of her dystonic symptoms.

BACKGROUND: Norepinephrine and phenylephrine are commonly used vasoactive drugs to treat hypotension during the perioperative period. The increased release of endogenous norepinephrine elicits prothrombotic changes, while parturients are generally in a hypercoagulable state. Therefore, this trial aims to investigate whether there is a disparity between equivalent doses of prophylactic norepinephrine infusion and phenylephrine infusion on prothrombotic response in patients undergoing cesarean section under spinal anesthesia. METHODS: Sixty-six eligible parturients will be recruited for this trial and randomly assigned to the norepinephrine or phenylephrine group. The "study drug" will be administered at a rate of 15 ml/h starting from the intrathecal injection. The primary outcome are plasma coagulation factor VIII activity (FVIII: C), fibrinogen, and D-dimer levels. The secondary outcomes include hemodynamic variables and umbilical artery blood pH value. DISCUSSION: Our study is the first trial comparing the effect of norepinephrine and phenylephrine on prothrombotic response in patients undergoing cesarean section under spinal anesthesia. Positive or negative results will all help us better understand the impact of vasoactive drugs on patients. If there are any differences, this trial will provide new evidence for maternal choice of vasoactive medications in the perioperative period.

OBJECTIVE: To look into the effects of different anesthesia methods on the labor process and the expression of serum estrogen and progesterone in primiparas with painless labor. METHODS: 60 primiparas receiving painless labor were selected as the research objects, and they were divided into either a Spinal & Continuous epidural anesthesia group (n = 30) or a continuous epidural anesthesia group (n = 30), anesthesia is administered using the corresponding anesthesia method. The authors compared serum estrogen and progesterone, inflammatory index expression, pain degree and neonatal health status in different periods. RESULTS: At T2 and T3, serum P, LH, FSH and E2 levels in the Spinal & Continuous epidural anesthesia group were signally lower than those in the Spinal & Continuous epidural anesthesia group (p < 0.05). Spinal & Continuous epidural anesthesia group harbored faster onset and longer duration of sensory block and motor block than the Continuous epidural anesthesia group (p < 0.05). SAS and SDS scores of the Spinal & Continuous epidural anesthesia group were clearly lower than those of the Continuous epidural anesthesia group (p < 0.05). VAS score and serum TNF-α, IL-6 levels of pregnant women in the Spinal & Continuous epidural anesthesia group were memorably lower than those in the Continuous epidural anesthesia group at T2 and T3 (p < 0.05). The total incidence of postoperative complications in the Spinal & Continuous epidural anesthesia group was distinctively lower than that in the Continuous epidural anesthesia group (p < 0.05). CONCLUSION: Spinal anesthesia combined with continuous epidural anesthesia has a better anesthesia effect in the painless labor of primiparas, which can effectually ameliorate the labor process and the expression of serum estrogen and progesterone.

INTRODUCTION: Peripheral vasodilation causes a redistribution of body temperature from the core to the periphery, resulting in shivering and hypothermia. These are normal pathological and physiological processes during spinal anaesthesia. Two drugs, norepinephrine and phenylephrine, have peripheral vasoconstrictive effects. It is unclear the effects of norepinephrine and phenylephrine on shivering and hypothermia in patients undergoing caesarean section under spinal anaesthesia. METHODS ANALYSIS: 240 eligible parturients will be recruited for this randomised, double-blind, controlled trial and randomly assigned to either the norepinephrine or phenylephrine groups. The primary outcome will be the incidence of shivering while secondary outcomes will include the severity of shivering, rectal temperature, incidence of hypothermia and umbilical artery blood pH value. ETHICS AND DISSEMINATION: The Institutional Ethics Committee of The Second People's Hospital of Hefei approved the trial protocol (ID: 2023-093). The results will be published in a compliant journal. The original data will be released in December 2029 on the ResMan original data-sharing platform of the China Clinical Trial Registry (http://www.medresman.org.cn).

BACKGROUND: Cesarean delivery (CD) is one of the most common surgeries performed worldwide, with increasing yearly rates. Although neuraxial techniques remain the preferred anesthesia method for CD, maternal thrombocytopenia remains a prominent contraindication. Formation of spinal\epidural hematomas are extremely rare, however the minimal thrombocyte count required for safe neuraxial anesthesia is still under debate. Although transfusion of thrombocytes for the purpose of neuraxial anesthesia is still not recommended, patients with severe thrombocytopenia (less than 50 × 103/uL) are given thrombocyte transfusion for surgical hemostasis. OBJECTIVES: To evaluate the anesthetic approach to caesarean deliveries in parturients with severe thrombocytopenia who received thrombocyte transfusion aimed for improved surgical hemostasis. METHODS: We conducted a single center, retrospective cohort study. Results: A total of five cases were found, four of which were given spinal anesthesia immediately following thrombocyte transfusion. One patient was denied spinal anesthesia because her thrombocyte count following transfusion failed to reach safe levels. None of our cases had anesthesia-related complications recorded. CONCLUSIONS: We examined the anesthetic management parturients with severe thrombocytopenia who needed cesarean delivery and were transfused with thrombocytes for surgical hemostasis. In such cases, spinal anesthesia may be considered due to the serious risks associated with general anesthesia.

BACKGROUND: Cesarean deliveries (CD) are commonly performed using neuraxial anesthesia. The use of neuraxial morphine has proven beneficial in terms of postoperative pain management; however, its effect on postoperative urine retention remains unclear. OBJECTIVES: To determine whether morphine injection into the neuraxis during CD influences postoperative urinary retention rate. METHODS: We conducted a retrospective case-control observational study of patients undergoing CD. We compared patients using morphine injected into the intrathecal or epidural spaces (November 2020 to October 2021) to a historical cohort of patients undergoing CD without morphine (November 2019 to October 2020). The primary outcome was the rate of postoperative overt urinary retention necessitating bladder catheterization. RESULTS: The study group comprised 283 patients, and 313 patients in the control group were eligible for analysis. No differences were found with respect to the baseline demographic and indication for CD. The number of postpartum urinary bladder catheterizations due to urine retention was higher in the study group (5% vs. 1%, P-value = 0.003). No cases of 30-day readmission were recorded. Moreover, patients treated with neuraxial morphine required fewer repeat doses of postoperative anesthesia (oral analgesia 7.4 vs. 10.1, intravenous analgesia 0.29 vs. 0.31, oral opioids 0.06 vs. 3.70, intravenous opioids 0.01 vs. 0.45, P-value < 0.001 for all). CONCLUSIONS: While neuraxial morphine used during CD appears to be safe and effective, the risk of postoperative urinary retention seems to be increased due to its use. Cases of overt urinary retention treated by bladder catheterization does not lead to short-term complications.

Anesthesia clinicians often navigate a delicate balance between maternal and fetal safety. Interventions for at fetal well-being may introduce risks of harm to the mother and raise ethical dilemmas. Emergency procedures often focus on direct fetal safety, sidelining maternal physical and mental well-being. The clash between ethical principles, particularly nonmaleficence and beneficence, often arises, with maternal autonomy guiding decisions. Fetal surgery exemplifies risking maternal health for fetal benefit, whereas emergent cesarean deliveries pose physical and psychological challenges for both the mother and child.

BACKGROUND: External cephalic version (ECV) is a medical procedure in which an extracorporeal manipulation is performed to render the breech presentation (BP) fetus in the cephalic position. The use of anesthesia to facilitate repositioning has been evaluated in various randomized clinical trials (RCTs), but its potential effectiveness remains controversial. METHODS: A systematic literature search was carried out in 8 electronic databases. In the meta-analysis, a random effects model was used to calculate the pooled relative risk (RR) and its 95% confidence interval (CI), and the pooled standardized mean difference (SMD) and its 95% CI, in order to systematically assess the effect of anesthesia on the success rates of ECV, vaginal delivery, cesarean delivery as well as other outcomes. Relevant subgroup analyses, publication bias test and sensitivity analyses were also conducted. RESULTS: This review included 17 RCTs. Women who received anesthesia had a significantly higher incidence of successful ECV (RR: 1.37, 95% CIs: 1.19-1.58) and vaginal delivery (RR: 1.23, 95% CIs: 1.03-1.47), and a significantly lower incidence of cesarean delivery (RR: 0.69, 95% CIs: 0.53-0.91), compared with those who did not. CONCLUSION: The administration of anesthesia not only significantly reduces maternal pain but also significantly increases the success rate of ECV in women with malpresentation at term, leading to a significant rise in the incidence of vaginal delivery. However, it may increase the incidence of maternal hypotension. SYSTEMATIC REVIEW REGISTRATION: The protocol was prospectively registered with PROSPERO, registration CRD42022381552.

BACKGROUND: The aim of this study was to evaluate the impact of intravenous palonosetron compared to ondansetron on hypotension induced by spinal anesthesia in women undergoing cesarean section. METHODS: Fifty-four women scheduled for elective cesarean section were, randomly allocated to ondansetron group (n = 27) or palonosetron group (n = 27). Ten minutes prior to the administration of spinal anesthesia, participants received an intravenous injection of either ondansetron or palonosetron. A prophylactic phenylephrine infusion was initiated immediately following the intrathecal administration of bupivacaine and fentanyl. The infusion rate was titrated to maintain adequate blood pressure until the time of fetal delivery. The primary outcome was total dose of phenylephrine administered. The secondary outcomes were nausea or vomiting, the need for rescue antiemetics, hypotension, bradycardia, and shivering. Complete response rate, defined as the absence of postoperative nausea and vomiting and no need for additional antiemetics, were assessed for up to 24 hours post-surgery. RESULTS: No significant differences were observed in the total dose of phenylephrine used between the ondansetron and palonosetron groups (387.5 µg [interquartile range, 291.3-507.8 µg versus 428.0 µg [interquartile range, 305.0-507.0 µg], P = 0.42). Complete response rates also showed no significant differences between the groups both within two hours post-spinal anesthesia (88.9% in the ondansetron group versus 100% in the palonosetron group; P = 0.24) and at 24 hours post-surgery (81.5% in the ondansetron group versus 88.8% in the palonosetron group; P = 0.7). In addition, there was no difference in other secondary outcomes. CONCLUSION: Prophylactic administration of palonosetron did not demonstrate a superior effect over ondansetron in mitigating hemodynamic changes or reducing phenylephrine requirements in patients undergoing spinal anesthesia with bupivacaine and fentanyl for cesarean section.

The risks and benefits of spinal anaesthesia must be assessed in patients with coagulation disorders. A woman in her 20s with congenital factor VII (FVII) deficiency (31%) was admitted at 38 weeks for caesarean delivery. A rotational thromboelastometry (ROTEM) analysis showed normal coagulation and spinal anaesthesia was performed safely. A repeated ROTEM analysis after haemostasis and uterine closure showed normal coagulation without fibrinolysis. No prophylactic FVII was administered, resulting in a cost savings of US$12 884. FVII level did not predict bleeding or fibrinolysis and FVII and tranexamic acid were not indicated.

A primigravida in mid 30s presented to hospital at 30+2 weeks gestation, due to progressive neurological symptoms including ascending limb weakness and paraesthesia bilaterally as well as dysphagia, facial weakness and dysphasia.The patient was diagnosed with Guillain-Barré syndrome after physical examination and electromyography, which showed a patchy demyelinating sensorimotor polyneuropathy. The patient underwent a 5-day course of intravenous immunoglobulin, beginning the day after admission. Markers of severity including forced vital capacity improved thereafter until delivery.With limited evidence favouring one particular anaesthetic technique in parturients with Guillain-Barré syndrome, combined spinal epidural anaesthesia was preferred over general anaesthesia in order to avoid the potential for prolonged intubation postoperatively and to allow careful titration of neuraxial blockade. Delivery by caesarean section at 34+1 weeks due to pre-eclampsia was uncomplicated. Thereafter the patient's condition deteriorated, requiring a further 5-day course of intravenous immunoglobulin with symptoms gradually improving over a 6-month admission.

BACKGROUND: Use of a programmed intermittent epidural bolus (PIEB) regimen during labour is associated with several benefits over a continuous epidural infusion (CEI), including reduced local anaesthetic consumption and reduced risk of motor block. We hypothesise that the benefits of a PIEB regimen may vary according to the Robson Ten Group Classification System (TGCS). The aim of this study was to determine if introduction of a PIEB regimen was associated with reduced incidence of motor block. We also wished to examine changes in obstetric outcomes following PIEB introduction across the Robson TGCS. METHODS: This was a single-centre retrospective cohort study. Data were collected over two three-month periods before and after PIEB introduction. The primary outcome was the incidence of motor block. Maternal and obstetric outcomes across Robson Groups 1-4 were analysed. RESULTS: Introduction of PIEB was associated with reduced incidence of motor block (28.4% (95% CI 25.7% to 31.3%) vs 22.4%, (95% CI 19.9% to 25.2%), difference 5.9% (95% CI 1.0% to 21.1%), P=0.003), with no association with changes in rates of caesarean section, operative vaginal delivery or other obstetric outcomes. Use of a PIEB regimen was associated with reduced incidence of motor block in Robson Group 4a (20.3% (16.0%, 28.0%) vs 12.0%, (7.6%, 16.4%), difference 9.9% (95% CI -17.4% to -2.4%) P=0.009). There were no significant changes in other outcomes assessed across Robson TGCS. CONCLUSION: Introduction of PIEB for maintenance of labour analgesia was associated with reduced incidence of motor block in our institution compared with CEI. Presenting results according to Robson's TGCS in future studies may allow better elucidation of the impact of neuraxial analgesia on maternal and obstetric outcomes.

Pregnant women with severe osteogenesis imperfecta (OI) are uncommon, and there are limited data regarding anaesthesia for caesarean section in these high-risk individuals. The presence of anatomical and physiological abnormalities can pose technical challenges for the anaesthetist. This report describes the successful implementation of epidural anaesthesia in a parturient with severe OI. To our knowledge, this is the first documented use of ultrasound-assisted neuraxial anaesthesia and wrist blood pressure monitoring in such patients undergoing caesarean section. Understanding the pathophysiological changes associated with OI is crucial for ensuring safe administration of anaesthesia to these women.

A 32-year-old multigravida woman, with known familial hypokalaemic periodic paralysis, underwent spinal anaesthesia for an elective lower segment caesarean section. There are several case reports in the literature discussing the optimal anaesthetic technique. In the past there has not been an emphasis on aggressive and early potassium replacement. A target level to commence replacement of potassium at 4.0 mmol/L or less is proposed. Careful preoperative preparation, frequent perioperative monitoring and early potassium replacement resulted in no perioperative episodes of weakness in this case, in contrast with other case reports where potassium was either not monitored or not replaced early enough, resulting in postoperative attacks. Another factor to consider in hypokalaemic periodic paralysis is the avoidance of triggers, including certain medications. Misoprostol was used in this instance to avoid potential electrolyte derangements from other uterotonics.

BACKGROUND AND OBJECTIVE: Spinal anesthesia remains the preferred mode of anesthesia for preeclamptic patients during cesarean delivery. We investigated the incidence of maternal hypotension under spinal anesthesia during cesarean delivery, by comparing different prophylactic infusion rates of norepinephrine with normal saline. METHODS: We randomly allocated 180 preeclamptic patients (45 in each groups) aged 18-45 scheduled for cesarean delivery to receive one of four prophylactic norepinephrine infusions at doses of 0 (normal saline group), 0.025 (0.025 group), 0.05 (0.05 group), or 0.075 (0.075 group) µg/kg/min following spinal anesthesia. The primary endpoint was the incidence of maternal hypotension (systolic blood pressure < 80% of baseline). RESULTS: The incidence of maternal hypotension was reduced with different prophylactic infusion rates of norepinephrine (26.7%, 15.6%, and 6.7%) compared with normal saline (37.8%) with a significant decreasing trend (p = 0.002). As the infusion doses of norepinephrine increased, there is a significant decreasing trend in deviation of systolic blood pressure control (median performance error; median absolute performance error) from baseline (p < 0.001; p < 0.001) and need for rescue norepinephrine boluses (p = 0.020). The effective dose 50 and effective dose 90 of prophylactic norepinephrine infusion were - 0.018 (95% confidence interval - 0.074, 0.002) µg/kg/min and 0.065 (95% confidence interval 0.048, 0.108) µg/kg/min, respectively. CONCLUSIONS: Prophylactic infusion of norepinephrine, as compared to no preventive measures, can effectively reduce the incidence of maternal hypotension in preeclamptic patients under spinal anesthesia during cesarean delivery, without increasing other adverse events for either the mother or neonate.

This review aims to assess the published evidence on airway management with a supraglottic airway device (SGA) for general anaesthesia in patients requiring a caesarean section. Physiological changes during pregnancy can make airway management in parturients challenging. At the same time, pregnant patients are at risk of pulmonary aspiration due to hormonal and mechanical alterations. The standard airway management for parturients undergoing caesarean section is rapid sequence induction followed by tracheal intubation. Evidence exists that using second-generation SGA devices is well tolerated and effective in selected patients. In this review, we provide an overview of the existing evidence and provide an algorithm to make an evidence-based clinical decision on the use of SGA devices. An online literature search was performed in Medline, Embase, PubMed, Emcare, Cochrane Library and CINAHL. The search terms used were 'supraglottic airway', 'supraglottic airway device', 'supraglottic airway management', 'supraglottic tube', 'i-gel', laryngeal mask', 'laryngeal mask airway', 'LMA', 'SGA', 'Proseal', 'Supreme', 'obstetric surgery', 'obstetric operation', 'general anaesthesia', 'caesarean' or 'caesarean section', 'abdominal delivery'. Full-text articles in English, Dutch and French were included. Case reports and studies in which the surgery was not a caesarean section were excluded. The initial search yielded 815 results. Following screening, deduplication and removal of publications that were unrelated to the topic or did not fit the inclusion criteria, 13 manuscripts were included in our analysis. A total of 7722 patients were described in the articles included. In the majority of manuscripts, second-generation SGA devices were used. There were seven cases of failed insertion and a need for conversion to tracheal intubation; first-generation SGA devices were used in these cases. There were no cases of pulmonary aspiration, and only one case of gastric regurgitation was described. Growing evidence suggests that the use of second-generation SGA devices might be well tolerated as the primary method for securing the airway for caesarean sections requiring general anaesthesia, in selected patients with a low risk for aspiration and difficult intubation.
