Emergency cesarean section has always been a challenge for patients, surgeons, and anesthesiologists, as it endangers the safety of both parturients and fetuses. Obesity and hypertension are common among pregnant women, but severe obesity combined with refractory hypertension is very rare in clinical practice. The optimal anesthetic management strategy for obese pregnant women with a difficult airway and poorly controlled hypertension remains debatable. This report presents a 32-year-old woman with severe obesity and refractory hypertension at 36 weeks and 6 days of pregnancy. Owing to fetal heart rate abnormalities, she was scheduled for emergency cesarean section. Given the urgency of the fetal condition and the challenges posed by the patient's obesity for epidural puncture, the anesthesiologist opted for rapid sequence induction and tracheal intubation instead of intervertebral anesthesia. Short-acting antihypertensive medications were adminstrated preoperatively to control elevated blood pressure, and vasopressor agents were continuously infused during surgery to prevent severe hypotension induced by anesthetic drugs. The entire anesthesia and surgical procedure proceeded uneventfully, with no major adverse events observed. Both the patient and fetus achieved favorable outcomes. This case indicates that early anesthetic risk assessment and meticulous pre-delivery planning are paramount, necessitating personalized management of airway and hemodynamics to optimize outcomes in obese parturients.

OBJECTIVE: To compare the therapeutic efficacy and safety of local anesthesia and spinal anesthesia for the patients with varicocele (VC) who underwent microsurgical varicocelectomy (MV). METHODS: We retrospectively analyzed the data of VC patients who underwent MV treatment at the Andrology Department of the Affiliated Ruikang Hospital of Guangxi University of Chinese Medicine from May 2020 to March 2023. Cases with complete clinical data and follow-up evaluation were selected and divided into a control group (spinal anesthesia) and an observation group (local anesthesia) according to different anesthesia methods. The surgical time (including anesthesia time), visual analogue scale (VAS) score for pain, hospital stay, treatment cost, sperm concentration, forward motile sperm rate, and normal sperm morphology rate after three months of surgery, as well as postoperative complications and recurrence rate were compared between the two groups. RESULTS: A total of 107 eligible cases were included, with 56 cases in the control group and 51 cases in the observation group. There was no significant difference in the VAS score for pain during and after four hours of surgery, as well as postoperative complications, and recurrence rate between the two groups (P> 0.05). There was an significant increase in sperm concentration, forward motile sperm rate, and normal sperm morphology rate in both of two groups after three months of surgery (P<0.05). However, there was no significant difference between the two groups three months after surgery (P>0.05). The surgical time and hospital stay were shorter than those of the control group (P<0.05). And the treatment cost in observation group was lower than that of the control group (P<0.05). CONCLUSION Both local anesthesia and lumbar anesthesia for MV treatment of VC have good efficacy and safety. However, patients treated with MV under local anesthesia for VC have obvious advantages in terms of operation time (including anesthesia time), hospital stay, and treatment cost, which is worthy of clinical promotion and application.

OBJECTIVES: To explore the relationship between the Observer's Assessment of Alertness/Sedation (OAAS) score and the bispectral index (BIS) during propofol titration for general anesthesia induction and analyze the impact of BIS monitoring delay on anesthetic depth assessment. METHODS: This study was conducted among 90 patients (ASA class I-II) undergoing elective surgery under general anesthesia. For anesthesia induction, the patients received propofol titration at the rate of 0.5 mg·kg^-1·min^-1 till OAAS scores of 4, 3, 2, and 1 were reached. After achieving an OAAS score of 1, remifentanil (2 μg·kg⁻¹) and rocuronium (0.6 mg·kg⁻¹) were administered, and tracheal intubation was performed 2 min later. BIS values, mean arterial pressure (MAP), heart rate (HR), and propofol dosage at each OAAS score were recorded, and the correlation between OAAS scores and BIS values was analyzed. The diagnostic performance of BIS values for determining when the OAAS score reaches 1 was analyzed using ROC curve. RESULTS: All the patients successfully completed tracheal intubation. BIS values of the patients at each of the OAAS scores differed significantly (P<0.01), and the mean BIS value decreased by 4.08, 8.32, 5.43 and 5.24 as the OAAS score decreased from 5 to 4, from 4 to 3, from 3 to 2, and from 2 to 1, respectively. There was a significant correlation between the OAAS score and BIS values (ρ=0.775, P<0.001). The median BIS value for an OAAS score of 1 was 76, at which point 83.33% of the patients had BIS values exceeding 60. ROC curve analysis showed that for determining an OAAS score of 1, BIS value, at the optimal cutoff value of 84, had a sensitivity of 88.9%, a specificity of 73.3%, and an area under the curve of 0.842 (0.803-0.881). CONCLUSIONS OAAS score during induction of general anesthesia is strongly correlated with BIS value and is a highly sensitive and timely indicator to compensate for the delay in BIS monitoring.

OBJECTIVES: To investigate the effect of intubation with electromyographic (EMG) endotracheal tubes versus conventional wire-reinforced (CWR) tubes on the incidence of postoperative sore throat (POST) in patients undergoing thyroidectomy under general anesthesia and identify the risk factors for POST. METHODS: We retrospectively collected the clinical data from a cohort of 245 patients undergoing elective thyroid surgery under general anesthesia at the Sixth Affiliated Hospital of Sun Yat-sen University between October, 2024 and March, 2025. Patients received intubation with either EMG endotracheal tubes (n=100) or CWR tubes (n=145) during the operation, and the incidences of POST and other postoperative complications were compared between the two groups. Propensity score matching (PSM) was applied to adjust for the baseline differences, and multivariate logistic regression analysis was used to identify independent risk factors for POST. RESULTS: Comparisons of the baseline data revealed significant differences between the two groups (P<0.05). After PSM, 90 patients in EMG group and 75 in CWR group were included in the final analysis with matching baseline characteristics (P>0.05). Post-matching analysis showed that the EMG group had a shorter operative time (P=0.002) but a higher incidence of POST (P=0.001). Multivariate logistic regression identified the use of EMG tubes (OR=17.50, 95% CI: 2.25-136.03, P<0.01) as an independent risk factor for POST. CONCLUSIONS Intubation with EMG endotracheal tubes can shorten the operative time and allow recurrent laryngeal nerve monitoring during thyroidectomy under general anesthesia, but their structural design may increase the risk of POST. Clinical decisions should be made to balance nerve protection and postoperative patient comfort by selecting appropriate tube types and optimizing intubation strategies to enhance perioperative outcomes.

INTRODUCTION: A previous prospective, randomised controlled trial showed that animated videos shown to children before magnetic resonance imaging (MRI) scan reduced the proportion of children needing repeated MRI sequences and improved confidence of the children staying still for at least 30 min. Children preferred the interactive video. We hypothesised that the interactive video is non-inferior to showing two videos (regular and interactive) in improving children's cooperativeness during MRI scans. METHODS: In this Institutional Review Board-approved prospective, randomised, non-inferiority trial, 558 children aged 3-20 years scheduled for elective MRI scan from June 2017 to March 2019 were randomised into the interactive video only group and combined (regular and interactive) videos group. Children were shown the videos before their scan. Repeated MRI sequences, general anaesthesia (GA) requirement and improvement in confidence of staying still for at least 30 min were assessed. RESULTS: In the interactive video group ( n = 277), 86 (31.0%) children needed repeated MRI sequences, two (0.7%) needed GA and the proportion of children who had confidence in staying still for more than 30 min increased by 22.1% after the video. In the combined videos group ( n = 281), 102 (36.3%) children needed repeated MRI sequences, six (2.1%) needed GA and the proportion of children who had confidence in staying still for more than 30 min increased by 23.2% after the videos; the results were not significantly different between the two groups. CONCLUSION The interactive video group demonstrated non-inferiority to the combined videos group.

OBJECTIVE: To investigate the effect of electroacupuncture pretreatment on the quality of recovery in the patients undergoing laparoscopic gastrointestinal surgery. METHODS: Sixty patients for elective laparoscopic resection of gastrointestinal tumors under general anesthesia were randomly assigned to either an observation group or a control group, with 30 patients in each group. In the control group, the routine inhalation-intravenous combined general anesthesia was adopted. On the basis of the control group, in the observation group, 30 min before anesthesia induction, electroacupuncture was applied to bilateral Neiguan (PC 6) and Neimadian (Extra) for 30 min, using disperse-dense wave and at 2 Hz/100 Hz. The recovery time of spontaneous breathing, awakening time, extubation time, and the post-anesthesia care unit (PACU) stay time were compared between the two groups. Mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SpO₂) were recorded at multiple time points: before electroacupuncture (T0), before extubation (T1), immediately after extubation (T2), 5 minutes (T3) and 10 minutes (T4) after extubation, and upon discharge from PACU (T5). The visual analogue scale (VAS) score for pain and Ramsay sedation score at T3, T4 and T5 were observed; and the incidence of agitation, nausea and vomiting at T5 was evaluated in the two groups. At T0 and T5, the serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and cortisol were determined in the two groups. RESULTS: In the observation group, the recovery time of spontaneous breathing, awakening time, extubation time, and PACU stay time were shorter (P<0.001), MAP and HR at T2 were lower (P<0.01, P<0.05), the VAS scores for pain at T3, T4, and T5 dropped (P<0.001, P<0.01), and the Ramsay sedation score at T3 reduced (P<0.05) compared with those in the control group. The incidence of nausea and vomiting was lower in the observation group when compared with that in the control group (P<0.05). In comparison with the indexes at T0, the serum levels of TNF-α, IL-6, and cortisol increased at T5 in both groups (P<0.01); and these indexes at T5 in the observation group were lower than those in the control group (P<0.01, P<0.05). CONCLUSION Electroacupuncture pretreatment can enhance the quality of recovery in the patients undergoing laparoscopic gastrointestinal tumor surgery, shorten the time for spontaneous breathing recovery, awakening, extubation and PACU stay, and attenuate postoperative pain and stress response.

OBJECTIVE: To explore the effect of auricular point pressure on anesthetic recovery in the patients undergoing laparoscopic cholecystectomy. METHODS: One hundred and forty patients undergoing laparoscopic cholecystectomy were randomized into a trial group (52 cases, 2 cases dropped out) and a control group (52 cases, 2 cases were eliminated). In the control group, the conventional anesthesia program and recovery intervention were adopted. In the trial group, on the basis of the regimen as the control group, the intervention of auricular point pressure was supplemented. The auricular points on the right side were selected, including sympathetic (AH_6a), brain (subcortex, AT₄), thalamus, exciting point, heart and sore center. One day before operation, the auricular point pressure started; and the auricular points were stimulated specially before anesthesia (T0), at the moment of operation ending (T1), when entering the recovery room, at the moment of the tube removal (T2) and in 10 min of the tube removal (T3), respectively; each auricular point was pressed for 1 min a time. The recovery time of spontaneous breathing, the time of eye opening, the removal time of endotracheal tube, the recovery time of orientation, and the time of exiting recovery room were compared between the two groups. The score of pain visual analogue scale (VAS) and that of Richmond agitation-sedation scale (RASS) at T2, T3 and when exiting recovery room (T4), and the relevant circulatory indexes (heart rate [HR], systolic blood pressure [SBP], diastolic blood pressure [DBP] and mean arterial pressure [MAP]) at T0, T1, T2 and T3 were observed in the two groups. RESULTS: In the trial group, the recovery time of spontaneous breathing, the time of eye opening, the removal time of endotracheal tube, the recovery time of orientation, the time of exiting recovery room were shorter than those of the control group (P<0.01, P<0.05). The pain VAS and RASS scores at T2, T3 and T4, as well as HR, SBP, DBP and MAP at T0, T1, T2 and T3 were not different statistically between the two groups (P>0.05). CONCLUSION Auricular point pressure can shorten the recovery time from anesthesia in the patients undergoing laparoscopic cholecystectomy.

Wide-awake local anesthesia has many advantages. We describe a new method to use wide-awake local anesthesia with more flexibility. A 32-year-old man with a severe right-hand contracture after an iatrogenic tourniquet accident during an anterolateral thigh flap for a partial hand amputation underwent contracture release using external fixation after proximal row carpectomy and subsequent tenolysis. We performed most of the tenolysis procedure under general anesthesia and the final stage with an intraoperative assessment of active finger movement and dissection under local anesthesia. He regained his grip strength 2.5 years post-injury. General anesthesia is useful to treat a surgical site with extensive hard scars, whereas local anesthesia is useful for adjusting tension in an awake patient. The indication for wide-awake surgery is yet to be established; our method of combining general and local anesthesia in the tenolysis procedure illustrates the possibilities in expanding this method.

INTRODUCTION: General anaesthesia is associated with higher maternal morbidity and mortality when compared with regional anaesthesia, related mainly to failure of intubation, hypoxia and aspiration. The aim of this retrospective review was to define the incidence of failed and difficult intubation in parturients undergoing general anaesthesia for Caesarean delivery at a high-volume obstetric hospital in Singapore. METHODS: All parturients who underwent Caesarean delivery under general anaesthesia from 2013 to 2016 were identified and their medical records were reviewed to extract pertinent data. Difficult intubation was defined as 'requiring more than one attempt at intubation or documented as such, based on the opinion of the anaesthetist'. A failed intubation was defined as 'inability to intubate the trachea, with subsequent abandonment of intubation as a means of airway management'. RESULTS: Records of 660 Caesarean sections under general anaesthesia were extracted. The mean age of the parturients was 32.1 ± 5.5 years and the median body mass index was 27.5 (interquartile range 24.6-31.1) kg/m². Rapid sequence induction with cricoid pressure was employed for all patients, with thiopentone and succinylcholine being administered for 91.2% and 98.1% of patients, respectively. There were 33 difficult intubations among 660 patients, yielding an incidence of 5.0%. Junior trainees performed about 90% of all intubations and 28 (84.8%) out of 33 difficult intubations. Repeat intubations were performed by senior residents/fellows (57.1%) and consultants (14.3%). No instance of failed intubation was reported. CONCLUSION The local incidence of difficult obstetric intubation was one in 20. No failure of intubation was observed.
