Mucopolysaccharidoses are rare lysosomal storage diseases resulting from defects in lysosomal enzymes involved in degradation of glycosaminoglycans. Different mucopolysaccharidoses are caused by different enzyme deficiencies The anesthetic complications are related to the organs involved. Patients with mucopolysaccharidoses are rare, and few anesthetists encounter such patients. We experienced a case of mucopolysaccharidoses type II. Several endotracheal intubation attempts were tried, but we experienced failed endotracheal intubation. And we decided to proceed with surgery under bag-mask ventilation because of the short operation time. There’s no desaturation time. And the patient’s spontaneous ventilation was recovered and awakened. We have also briefly discussed the pathophysiology, clinical features, and possible airway management options for patients with mucopolysaccharidoses type II.

Hypopharyngeal mass is an uncommon condition in the aerodigestive tract. There were only a few cases have been published in the medical literature. We experienced a case of incidentally detected hypopharyngeal mass during endotracheal intubation. Hypopharyngeal mass was located at the right posterior pharyngeal wall. The hypopharyngeal mass was small and not obstruct the glottis, and endotracheal intubation was performed successfully. We have also briefly discussed symptoms, diagnosis, and related problems during general anesthesia of hypopharyngeal mass.

Antimicrobial filters that prevent cross-contamination through anesthesia equipment are commonly used in operating rooms. Occlusion of this filter leads to the patient’s airway obstruction, which may lead to fatal outcomes. We report a case of the airway obstruction by antimicrobial filter occlusion during general anesthesia, and symptoms recovered immediately after removal of the filter.

Evans syndrome is an uncommon condition defined by the combination of immune thrombocytopenia and autoimmune hemolytic anemia in the absence of known underlying cause. Association of Evans syndrome with pregnancy is very rare, and only a few cases have been published in the medical literature. We experienced a case of Evans syndrome in pregnancy. Cesarean section was performed under general anesthesia without hemorrhagic complications at the 37th week of pregnancy following treatment with steroid, intravenous immunoglobulin, and transfusion of platelet concentrates. We have also briefly discussed the pathophysiology, the possible treatment options during pregnancy and prenatal outcome of Evans syndrome.

Monitoring cerebral oxygenation using a near infrared spectroscopy (NIRS) device is useful for estimating cerebral hypoperfusion and is available during liver transplantation (LT). However, high serum bilirubin concentration can interfere with NIRS because bilirubin absorbs near infrared light. We report a patient who underwent LT with a diagnosis of vanishing bile duct syndrome, whose regional cerebral oxygen saturation (rSO₂) remained below 15% even with alert mental status and SpO2₂ value of 99%. The rSO₂ values were almost fixed at the lowest measurable level throughout the intra- and postoperative period. We report a case of erroneously low rSO₂ values during the perioperative period in a liver transplant recipient which might be attributable to skin pigmentation rather than higher serum bilirubin concentration.

BACKGROUND: Previous studies have shown that measuring the distance from the skin to the ligamentum flavum by ultrasound preceding cervical epidural block can be beneficial in excluding false loss of resistance. However, the measurement value using ultrasound may vary depending on the degree of operator experience. Therefore, we aimed to determine the depth from skin to cervical epidural space by using lateral cervical spine X-ray, which is a more intuitive method. METHODS: We enrolled 102 adult patients who were scheduled to undergo cervical epidural anesthesia for vascular bypass surgery of upper arm. After attaching a steel rod on the needle insertion site, lateral cervical spine X-ray was taken before the epidural procedure. We measured the distance from the steel rod to the midpoint of interlaminar space on the spinolaminar line. The X-ray depth was compared with needle depth. RESULTS: Of the 102 enrolled patients, 18 patients including 13 in whom we were unable to measure X-ray depth were excluded from the analysis. In total, 84 patients were included in the analysis. Concordance correlation coefficient between the X-ray-measured depth and needle depth was 0.925. Bland-Altman analysis indicated a mean difference of ± 1.96 SD with 0.06 ± 0.56 cm. CONCLUSIONS: Lateral cervical spine X-ray can be useful for prediction of the midline depth from skin to epidural space, particularly for operators who are not skilled at spine ultrasound or the use the C-arm fluoroscopy.

We describe a case of a 35-year-old male patient who was scheduled for laparoscopic cholecystectomy and developed a life-threatening anaphylactic reaction 2 min after the administration of sugammadex. He manifested erythematous wheals on the entire body, dyspnea, hypotension, and tachycardia. These symptoms disappeared after the administration of epinephrine. The patient recovered and was discharged at postoperative day 5 without any complications. After 7 weeks, we performed a skin prick test, and there was a weakly positive reaction for sugammadex. This case is suspected anaphylaxis associated with sugammadex, and we need to be aware that the use of sugammadex is associated with a serious risk of anaphylaxis.

BACKGROUND: Corneal abrasion is one of the most common ophthalmic complications that occurs after general anesthesia. Although they can occur by direct contact with surgical drapes or masks, most occur as a result of the drying of the cornea exposed during general anesthesia due to a reduced amount of tear secretions, the loss of light reflex, or the loss of recognition of pain during the procedure. Thus, to prevent corneal abrasions during general anesthesia, proper eye protection is required. METHODS: Seventy-two patients (144 eyes) were divided into four groups as follows: 1) control group: careful manual eye closure; 2) adhesive tape group: a bandage attached over the eyelid; 3) ointment group: eye ointment placed into the eye followed by eye closure; and 4) ointment and tape group: eye ointment placed into the eye followed by a bandage attached over the eyelid, with the patient subjected to both methods for each eye. The National Eye Institute (NEI) scale, conjunctiva hyperemia scale, tear break-up time, and Schmer test were conducted before and after operation. RESULTS: No statistically significant difference was noted between groups regarding the NEI scale, conjunctiva hyperemia scale, tear break-up time, or Schirmer test. CONCLUSIONS: To prevent corneal abrasions in normal patients undergoing general anesthesia, eye taping, eye ointment application, or taping after eye ointment application will not significantly reduce the degree of corneal epithelial damage compared to manual eye closure.

66-year-old woman with amyotrophic lateral sclerosis was scheduled for closed reduction and external fixation of left tibio-fibula. Total intravenous anesthesia using 2% propofol and remifentanil was done without muscle relaxant to avoid possible postoperative respiratory complication and pulmonary aspiration. The surgery had done without difficulty and she recovered from anesthesia promptly without respiratory complication and pulmonary aspitation. She discharged satisfactorily 15 days after surgery.
