RESUMEN
We present a 25-year-old, gravida 2, para 1 woman who developed apparent local anesthetic systemic toxicity (LAST) following activation of an epidural catheter for an urgent cesarean delivery. The patient had a height of 150 cm, weight of 92 kg, body mass index of 41 kg/m2, and calculated ideal body weight of 40 kg. A combined spinal epidural anesthetic was placed and the spinal component did not provide anesthesia to clamping of the abdomen. Subsequently, 300 mg of lidocaine was administered through the epidural catheter in three 5 mL doses over 8 minutes and surgery commenced. Approximately 30 minutes following the final 5 mL dose of epidural lidocaine, the patient had progressive loss of consciousness and was difficult to arouse. A presumptive diagnosis of LAST was made, and 60 mL of 20% intravenous lipid emulsion was administered. The patient's mental status improved to baseline within 5 minutes of lipid emulsion administration, and she made a complete recovery. Anesthesiologists should consider using ideal body weight when calculating the maximum dosage of local anesthetics, and LAST should be part of the differential diagnosis when patients have altered mental status in the setting of local anesthetic administration that exceeds recommended dosages.
RESUMEN
Objective: Chronic postoperative pain (CPSP) is common after thoracic surgery, even after the less invasive video-assisted thoracoscopic surgery (VATS). This study investigated the effect of thoracic epidural anesthesia (TEA) on the development of CPSP. Materials: We retrospectively analyzed the data of patients who underwent VATS at our center between 2020 and 2022. The enrolled patients were divided into the epidural block (EPI) and patient-controlled intravenous analgesia (PCIA) groups. A telephone questionnaire was used to collect information regarding CPSP, which was defined as a numerical rating scale (VAS) score ≥1 at 3 or 6 months postoperatively. Additionally, statistical analyses were performed to identify the risk factors for CPSP in the two groups. Results: Overall, 894 patients completed the follow-up interviews at 3 and 6 months, with 325 and 569 patients in the PCIA and EPI groups, respectively. The incidence rates of CPSP in the PCIA group at 3 and 6 months were 16.9 % (95 % confidence interval [CI]: 9.3-32.7 %) and 13.5 % (95 % CI: 8.7-33.4 %), and 10.3 % (95 % CI: 8.1-30.5 %) and 3.6 % (95 % CI: 3.5-21.5 %) in EPI group, respectively. The incidence of CPSP at 3 months (P = 0.0048) and 6 months (P < 0.005) was statistically significant in both groups. Age and lymph node dissection were significantly associated with CPSP. Conclusions: Compared to PCIA, TEA was associated with a lower incidence of CPSP after VATS, and should be considered an important part of the analgesia regimen for patients with VATS.
RESUMEN
Objective: This study aimed to explore the optimal dose of dexmedetomidine as a 0.59% ropivacaine adjuvant for epidural anesthesia on perioperative hemodynamics and anesthesia efficacy in patients undergoing great saphenous varicose vein surgery. Methods: A total of 90 patients were randomly divided into three groups: 0.25 µg/kg dexmedetomidine combined with 0.59% ropivacaine epidural infusion group (ED1 group), 0.5 µg/kg dexmedetomidine combined with 0.59% ropivacaine epidural infusion group (ED2 group), and 0.75 µg/kg dexmedetomidine combined with 0.59% ropivacaine epidural infusion group (ED3 group). Hemodynamics, anesthesia efficiency, and adverse reactions were recorded. Main results: Compared with the ED1 group, the ED2 group had lower systolic blood pressure at T1-3 (T1, 95%CIs, 6.52-21.93, p < 0.001; T2, 95%CIs, 2.88-18.21, p = 0.004; T3, 95%CIs, 0.49-18.17, p = 0.035), and the diastolic blood pressure at T1-2 was decreased (T1, 95%CIs, 4.55-14.36, p < 0.001; T2, 95%CIs, 0.37-12.17, p = 0.033). Compared with the ED2 group, the ED3 group had higher systolic blood pressure at T1-2 (T1, 95%CIs, 5.90-21.46, p < 0.001; T2, 95%CIs, 2.07-17.55, p = 0.008) and higher diastolic blood pressure at T1-3 (T1, 95%CIs, 2.91-12.81, p = 0.001; T2, 95%CIs, 1.32-13.23, p = 0.011; T3, 95%CIs, 0.14-11.52, p = 0.043). Compared with the ED2 group, the heart rate was significantly decreased at T1-4 in the ED3 group (T1, 95%CIs, 2.25-15.72, p = 0.005; T2, 95%CIs, 2.35-13.82, p = 0.003; T3, 95%CIs, 0.50-9.79, p = 0.025; T4, 95%CIs, 1.46-10.36, p = 0.005). The myocardial oxygen consumption in all three groups was significantly decreased at each time point compared to T0 (p < 0.05 or < 0.001), and no significant between-group differences were detected (P>0.05). Compared with the ED1 group, the anesthesia efficiency of ED2 and ED3 groups was markedly enhanced, but the risk of bradycardia in ED2 and ED3 groups was dramatically increased (6 of 28 [21.4%] vs. 14 of 30 [46.7%] and 14 of 27 [51.9%], p = 0.023), one patient in the ED3 group experienced difficulty urinating, and remaining adverse reactions were mild in all three groups. Conclusion: A measure of 0.5 µg/kg dexmedetomidine is the optimal dose as a 0.59% ropivacaine adjuvant for epidural anesthesia in patients undergoing great saphenous varicose vein surgery.

RESUMEN
BACKGROUND: The number of cesarean sections performed is increasing every year, and obstetric anesthesia is of great interest to physicians and research scholars because of its specificity, high risk, and high complication rate. OBJECTIVE: To investigate the effects of combined spinal epidural anesthesia (CSEA) with different intervertebral spaces during cesarean section on anesthesia effect, anesthesia onset time, anesthesia recovery time, maternal adverse reactions, and neonates. METHODS: Ninety-two women who underwent cesarean section in our hospital from September 2022 to February 2023 were selected as the study subjects and randomly divided them into two groups (group A and group B), 46 women in each group. Group A underwent CSEA via an L2-3 gap and group B underwent CSEA via an L3-4 gap puncture. The anesthesia effect, anesthesia onset time, sensory recovery time, adverse effects, and neonatal Apgar score were compared between the two groups. RESULTS: When CSEA was performed from L2-3, the anesthesia efficiency was higher, but the difference was not statistically significant. When anesthesia was performed by puncture from L2-3, the onset of anesthesia and recovery time was shorter, and the incidence of intraoperative maternal nausea and vomiting, hypotension, respiratory depression, and other adverse reactions was low with a statistically significant difference. However, the Apgar scores of the neonates in the two groups have no difference. CONCLUSIONS: When CSEA is induced via L2-3 interspace, anesthesia has a rapid onset of action, shorter recovery time, and few maternal adverse effects, without affecting the final anesthetic outcome.
RESUMEN
A 69-year-old female with Crohn's disease was admitted for open ileocecectomy with lysis of adhesions. The plan was to proceed with general endotracheal anesthesia and a thoracic epidural catheter for perioperative analgesia. Epidural access was attempted at the T10-11 and T11-12 interspaces, both of which resulted in accidental dural punctures. On the third attempt, the epidural catheter was inserted at the T9-10 interspace. Both the aspiration and test dose were negative. Thirty minutes later, after induction of general anesthesia, the catheter was again aspirated before the epidural pump was connected. Freely flowing, glucose-positive fluid was obtained, and the catheter was removed for the patient's safety. This case suggests that accidental dural puncture may be a risk factor for inappropriate communication with the subarachnoid space. This can be assumed to increase the risk of unanticipated high or total spinal block and its life-threatening sequelae.
RESUMEN
PURPOSE: This study aimed to estimate the median effective dose of intrathecal isobaric ropivacaine without opioid required for adequate cesarean delivery anesthesia after epidural labor analgesia. METHODS: Patients aged 20-40 years with American Society of Anesthesiology scores of I-II, body mass index ≤ 36, who underwent emergency cesarean delivery after failed vaginal delivery with epidural analgesia of a duration ≤ 6 h were included in the study. After removal of the epidural used for labor analgesia, a new combined spinal epidural was performed, and a dose of intrathecal isobaric ropivacaine without opioid was administered. The dose was determined using up-down methodology, with the starting patient's dose set to 12 mg. Adequate anesthesia, defined as a pinprick level no lower than T6 at 5 min after ropivacaine administration, resulted in the next patient receiving a dose of ropivacaine 1 mg higher, and inadequate anesthesia 1 mg lower. The primary outcome was the median (95% confidence interval (CI)) dose of spinal ropivacaine required for adequate cesarean delivery anesthesia. RESULTS: Of the 46 patients included in the study, 40 were analyzed. The median spinal ropivacaine dose was 8.11 mg (95% CI 7.29-8.93 mg) by the Dixon and Mood method and 8.06 mg (95% CI 6.93-9.00 mg) by isotonic regression. Two patients had high spinal anesthesia. CONCLUSION: Our findings suggest that for 50% of patients undergoing cesarean delivery after failed vaginal delivery with epidural analgesia, an 8-mg spinal dose of isobaric ropivacaine without opioid provides an anesthesia level no lower than T6 at 5 min.
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.

Choloepus didactylus (two-toed sloth) is a Xenarthran mammal whose morphology has so far been little studied. Given the increasing number of sloths requiring clinical and surgical interventions, this lack of clarity regarding anatomical features and landmarks has had a negative impact on veterinary decision-making for this species. We therefore sought to describe the topography of the medullary cone (MC) of Choloepus didactylus in order to provide guidance to qualified professionals on the ideal access for locoregional anesthesia. In evaluating four specimens, radiographs and dissections revealed that Choloepus didactylus has three lumbar vertebrae and five sacral vertebrae. The lumbar intumescence is located between T14 and the cranial half of L2, the medullary cone is located between the caudal half of L2 and L3, with an average length of 2.26 cm, and the cauda equina extends from S1 to S5. Based on these anatomical findings, we propose that the lumbosacral region would be the most suitable target for epidural anesthesia in Choloepus didactylus.
RESUMEN
Background: Factor (F)XI deficiency is a rare bleeding disorder with a poor correlation between bleeding tendency and FXI level. Management of pregnant women with FXI deficiency is not clearly established, especially regarding neuraxial analgesia (NA). Objectives: A retrospective multicenter observational study was conducted in French hemostasis centers on pregnant women with FXI of <60 IU/dL. Methods: Data to report were (i) FXI levels before pregnancy and at time of delivery, (ii) type of NA and delivery management modalities, and (iii) possible complications related to NA and bleeding complications. Results: Three hundred fourteen pregnancies in patients with FXI deficiency of <60 IU/dL were reported (from 20 centers); among them, 199 NA procedures have been completed (137 epidurals and 61 spinals, 1 had both). The period of childbirth was mostly from 2014 to 2020 (281/314; 89.5%). Congenital FXI deficiency was established with certainty by investigators in 32.8% patients (n = 103). Previous bleedings were described in 20.4% of the patients (64/314; 45.3% cutaneous, 31.3% gynecologic, and 15.6% postsurgical). Thirteen deliveries had an NA procedure with FXI of <30 IU/dL, 42 with FXI of 30-40 IU/dL, and 118 with FXI of 40-60 IU/dL. Median FXI levels at delivery in the epidural and spinal groups were not significantly different but were significantly lower in the group without NA by medical staff contraindications. There were no complications related to NA. A 17.5% postpartum hemorrhage or excessive postpartum bleeding incidence was reported, which is consistent with previous data. Conclusion: Our data support the use of a 30 IU/dL FXI threshold for NA, as suggested by the French proposals published in August 2023.
RESUMEN
PURPOSE: We developed a 3D-printed phantom model for ultrasound-guided caudal block for educational or training purposes because there have been no reports of the 3D-printed phantom model for ultrasound-guided caudal block. This study aimed to identify the needs for the phantom model in a lecture and demonstration at hands-on training (HoT) to promote the use of caudal block for sufficient pain control during high-dose-rate intracavitary/interstitial brachytherapy for gynecological cancers. MATERIALS AND METHODS: The sacrum and formwork were designed by computed tomography imaging. A 3D-modeling software program was used to create the sacrum and formwork. The phantom was solidified by injecting a gelatin-based gel. Ultrasonography was performed to visualize the sacral hiatus and puncture needle in the phantom. In October 2023, 10 radiation oncologists who did not perform caudal block in daily clinical practice from ten Japanese facilities participated in HoT on ultrasound-guided caudal block. After the HoT, questionnaires were distributed to each participant, and feedback was obtained through online channels. RESULTS: After receiving a lecture and demonstration on ultrasound-guided caudal block, 90% of the respondents would like to practice the procedure in their daily clinical practice. Moreover, 100% of the respondents would like to use the 3D-printed phantom model for ultrasound-guided caudal block for educational or training purposes. CONCLUSION: The 3D-printed phantom model for ultrasound-guided caudal block can be used in training and is in demand for facilities introducing caudal block.

Exercise induced anaphylaxis (EIA) is a rare and potentially life-threatening syndrome characterized by anaphylaxis provoked by exercise. Although vaginal delivery with labor pain is a physical strain for women and a possible trigger for EIA, no consensus exists on the management strategy of delivery in patients with EIA. A 28-year-old primigravida was referred to our hospital because of history of EIA, associated with pruritus, urticaria, and respiratory distress, exacerbated during physical activity. To avoid physical stress, we chose scheduled labor induction with epidural anesthesia, and administered prophylactic intravenous hydrocortisone. She delivered vaginally with no symptoms suggestive of EIA during labor. Since it is quite possible for patients with EIA to develop anaphylaxis during vaginal delivery with labor pain, epidural anesthesia and prophylactic steroid administration may be the most rational approaches for delivery in pregnant women with EIA.

BACKGROUND: This study investigated the optimal concentration of ropivacaine epidural anesthesia for clinical use in percutaneous transforaminal endoscopic discectomy (PTED) by comparing the effects of different concentrations. METHODS: Seventy patients scheduled for their first PTED procedure were enrolled in this randomized controlled trial. Patients were randomized to receive ropivacaine at varying concentrations (0.3% or 0.4%). Primary outcome measures included the numeric rating scale (NRS) and hip extension level (HEL). Secondary outcome measures included intraoperative fentanyl dosage and postoperative complications. RESULTS: One patient withdrew due to severe postoperative complications. The remaining 69 patients were allocated to the 0.3% (n = 34) and 0.4% (n = 35) groups, respectively. Baseline characteristics showed no significant differences between the two groups (P > 0.05). The NRS score was significantly lower in the 0.4% group than in the 0.3% group (P < 0.01), whereas the HEL score was significantly higher (P < 0.001). The average fentanyl dose in the 0.4% group was significantly lower than that in the 0.3% group (P < 0.01). Postoperative complications occurred in five and two patients in the 0.3% and 0.4% groups, respectively. CONCLUSION: Although 0.4% ropivacaine (20 mL) impacts muscle strength, it does not impede PTED surgery. Given its effective analgesic properties and few postoperative complications, 0.4% ropivacaine can be considered a preferred dose for PTED. TRIAL REGISTRATION: This study was registered with the Chinese Clinical Trials Registry (Registration number: ChiCTR2200060364; Registration Date: 29/5/2022) and on chictr.org.cn ( https://www.chictr.org.cn/showproj.html?proj=171002 ).

BACKGROUND: Delayed spinal epidural hematoma (SEH) following central neuraxial block (CNB) is a rare but serious complication. The underlying causes of SEH associated with neuraxial anesthesia are still unclear. Furthermore, the decision between surgical intervention and conservative management for SEH remains a complex and unresolved issue. CASE PRESENTATION: We report a case of delayed SEH in a 73-year-old woman who underwent vaginal hysterectomy under combined spinal-epidural anesthesia, with the administration of postoperative anticoagulants to prevent deep vein thrombosis on the 1st postoperative day (POD). She experienced symptoms 56 h after CNB. Magnetic resonance imaging (MRI) revealed a dorsal SEH at the L1-L4 level with compression of the thecal sac. On conservative treatment, full recovery was achieved after six months. CONCLUSIONS: This case reminds anesthesiologists should be alert to the possible occurrence of a delayed SEH following CNB, particularly with the administration of anticoagulants. Immediate neurological evaluation of neurological deficit and MRI are advised. Conservative treatment combined with close and dynamic neurological function monitoring may be feasible for patients with mild or nonprogressive symptoms even spontaneous recovery.

PURPOSE: The causes of epidural catheter migration beneath the skin have not been previously investigated. We hypothesized that greater subcutaneous fat thickness might be associated with increased catheter migration beneath the skin. METHODS: We conducted a retrospective cross-sectional study of patients who had undergone combined general and epidural anesthesia, selecting individuals who received thoracic and abdominal CT scans within the first 5 postoperative days. Needle depth was defined as the distance from the needle tip to the skin surface when the anesthesiologist determined that the needle tip had reached the epidural space. We measured the length of the epidural catheter from the skin surface to the epidural space (catheter length), and subcutaneous fat thickness (fat thickness) using CT imaging. Migration distance was calculated by subtracting needle depth from catheter length. RESULTS: We analyzed 127 patients (72 males), all undergoing epidural catheter insertion in the left lateral decubitus position via a paramedian approach. The median age of the patients was 71 years. Epidural catheters were postoperatively found to substantially curve beneath the skin. Regression analysis revealed no significant influence of fat thickness on catheter length (regression coefficient 0.10, 95% confidence interval [CI]: - 0.17, 0.38). However, it indicated a positive correlation between fat thickness and needle depth (regression coefficient 0.50, 95% CI: 0.30, 0.70), and a negative correlation between fat thickness and migration distance (regression coefficient - 0.40, 95% CI: - 0.65, - 0.14). CONCLUSION: We found a negative correlation between epidural catheter migration beneath the skin and subcutaneous fat thickness. Anesthesiologists should be aware of the possibility of substantial subcutaneous curving of the catheter, especially in patients with scant subcutaneous fat.
RESUMEN
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.

Friedreich's ataxia (FRDA), a rare inherited neurodegenerative disease, presents distinctive complexities in obstetrical anesthesia. Available research about FRDA in obstetrics is extremely limited. In this report, the anesthetic management of a 40-year-old primigravida with FRDA undergoing cesarean delivery is presented. An uneventful cesarean delivery with effective epidural anesthesia with ropivacaine at the L2-L3 intervertebral space was performed in our case. Neither hypotension nor bradycardia was observed, and vital signs remained stable, with no need for administration of vasoactive drugs. After discharge, the parturient reported no change in her neurologic symptoms. Conclusive recommendations are contingent upon more extensive studies. Overall management and the choice to proceed with neuraxial anesthesia in a woman with FRDA should be based on comprehensive consultations in both cardio-obstetrics and pre-anesthetic evaluations.
RESUMEN
PURPOSE: Post-operative pain after video-assisted thoracoscopic surgery is often treated using thoracic epidural analgesics or thoracic paravertebral analgesics. This article describes a case where a thoracic disc herniation is treated with a thoracoscopic microdiscectomy with post-operative thoracic epidural analgesics. The patient developed a bupivacaine pleural effusion which mimicked a hemothorax on computed tomography (CT). METHODS: The presence of bupivacaine in the pleural effusion was confirmed using a high performance liquid chromatography method. RESULTS: The patient underwent a re-exploration to relieve the pleural effusion. The patient showed a long-term recovery similar to what can be expected from an uncomplicated thoracoscopic microdiscectomy. CONCLUSION: A pleural effusion may occur when thoracic epidural analgesics are used in patents with a corridor between the pleural cavity and epidural space.

OBJECTIVE: To determine the association between timing of indwelling catheter removal and urinary retention after cesarean. DESIGN: Retrospective cohort study. SETTING: Eight hospitals in suburban, rural, and urban Colorado and Montana. PARTICIPANTS: Women who gave birth by cesarean from January 1, 2021, to April 30, 2022 (N = 3,496). METHODS: We categorized participants who gave birth between January 1, 2021, and June 29, 2021, (before implementation of the Enhanced Recovery After Surgery initiative) into Group A and participants who gave birth between July 1, 2021, and April 30, 2022, (after implementation of the Enhanced Recovery After Surgery initiative) into Group B. We used descriptive statistics to report the proportion of participants in both groups who experienced urinary retention after birth. We performed chi-square tests to determine the association between the time of catheter removal and incidence of urinary retention. We used the Wilcoxon rank sum test to determine the association between length of stay and urinary retention. RESULTS: Urinary retention rates were 5.8% in Group A and 12.6% in Group B (p < .001). In both groups, participants who received epidural anesthesia experienced significantly more urinary retention than those who received spinal anesthesia (p < .001). Participants who received epidural anesthesia and experienced urinary retention pushed 16.9% longer than those without urinary retention (p < .001). The proportion of participants who experienced urinary retention after catheter removal was 19.4% at 7 hours, 4.6% at 16 hours, and 9.9% at 12 hours after birth. Length of stay was determined to be inconclusive. CONCLUSION: We determined that the optimal time of catheter removal to minimize the rate of urinary retention was 12 to 16 hours after cesarean among women who received morphine sulfate as the spinal anesthesia.
RESUMEN
Achondroplasia is a genetic condition characterized by skeletal dysplasia that results in characteristic craniofacial and spinal abnormalities. It is the most common form of short-limbed skeletal dysplasia. Additionally, a pregnant patient who is morbidly obese warrants specific anatomical and physiological considerations, such as a difficult airway with potential hypoxia, full stomach precautions, and a reduced functional residual capacity. Achondroplasia increases the risks of maternal and fetal complications. Although neuraxial techniques are generally preferred for cesarean sections, there is no consensus among patients with achondroplasia. We aimed to discuss the anesthetic challenges in an achondroplastic patient and report our regional anesthesia approach for an elective cesarean section.
