Pneumocephalus Following Combined Spinal-Epidural Anesthesia: A Case Report Analysis

Background: Combined spinal-epidural anesthesia (CSEA) is widely used in clinical anesthesia due to its rapid onset, reliable anesthetic effect, and strong controllability. Although advancements in technique have reduced the frequency and severity of common complications, reports of rare and serious complications such as pneumocephalus, remain scarce. Case Report: This article presents a case of pneumocephalus following CSEA in a middle-aged female patient undergoing surgery for an intrauterine space-occupying lesion. The patient experienced severe headache postoperatively, and imaging confirmed the presence of intracranial air. After receiving active symptomatic treatment, the patient recovered and was discharged. Conclusion: This case underscores the importance of adhering to standard anesthesia protocols and increasing awareness of rare CSEA complications, particularly the risk of pneumocephalus. Early recognition and timely management are crucial. There is a need to further enhance training and research in anesthetic procedures to improve clinical anesthesia quality and ensure patient safety.

Effects of combined spinal-epidural anesthesia on anxiety,labor analgesia and motor blocks in women during natural delivery

BACKGROUND The background of this study was analgesia in natural delivery.The combined spinal-epidural anesthesia has obvious analgesic effect on the parturients in natural labor,and combined spinal-epidural anesthesia has been widely used in anesthesia for various diseases.AIM To study the effects of combined spinal-epidural anesthesia on anxiety,labor analgesia,and motor blocks in parturients during natural delivery.METHODS A total of 120 women who gave birth at Changning District Maternal and Child Health Hospital between December 2021 to December 2022 were included;a random number table approach was employed to divide the women into a control group and a joint group,with each group consisting of 60 women.The control group was given epidural anesthesia,while the joint group was given combined spinal-epidural anesthesia.The visual analog scale(VAS)was used to evaluate the degree of maternal pain.Comparisons were made between the two groups’conditions of childbirth and the duration of labor.Apgar scores were used to evaluate the status of the newborns at birth;Self-rating Anxiety Scale(SAS)and General Self-Efficacy Scale(GSES)scores,umbilical artery blood gas analysis indices and stress indices were compared between the two groups;and the frequencies of motor block and postpartum complications were analyzed.RESULTS In comparison to the control group,in the joint group,the VAS scores for the first,second,and third stages of labor were lower(P<0.05).The rates of conversion to cesarean section and postpartum blood loss in the joint group were lower than those in the control group(P<0.05).No significant differences were observed in the Apgar score,the duration of the first stage of labor,or the total duration of labor between the two groups(P>0.05).The second and third stages of labor in the joint group were shorter than those in the control group(P<0.05).When compared to the control group,the postpartum SAS score of the joint group was lower,while the GSES score was greater(P<0.05).Between the control group and the joint group,the differences observed in pH,arterial carbon dioxide partial pressure,arterial oxygen partial pressure,or arterial hydrogen ion concentration were not significant(P>0.05).Nitric oxide,cortisol,and adrenaline levels were lower in the joint group than in the control group(P<0.05).There were no substantial differences in Bromage grade or rate of complications between the two groups(P>0.05).CONCLUSION For parturients during natural delivery,combined spinal-epidural anesthesia can reduce anxiety,provide labor analgesia,shorten labor time,and reduce postoperative stress levels but did not result in a motor block.

Anesthetic dilemmas in an achondroplastic patient undergoing elective cesarean section

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.A morbidly obese pregnant patient 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.
