Use of sugammadex in a patient with narrow angle glaucoma

An 86-year-old woman was scheduled to receive fourth reconstructive surgery for femoral bone fracture under general anesthesia. She had been suspected with narrow angle glaucoma due to headache and bloodshot eyes during gastroscopy. During transfer to our hospital, she fell down and suffered from the right femoral neck fracture. The patient underwent femoral head replacement under spinal anesthesia. Later, she received surgeries twice uneventfully under spinal anesthesia; removal and re-implantation of the femoral bone head due to infection of the implanted head. Six months later, she fell down again and femoral bone was fractured during rehabilitation. Anesthesia was induced with propofol followed by rocuronium 0.9 mg x kg(-1) i.v. Anesthesia was maintained with propofol and remifentanil, and rocuronium was administered to maintain PTC of 10 or less. The surgery was completed in 150 minutes. At the end of surgery, a laryngeal mask was inserted and the tracheal tube was removed. TOF ratio recovered to 80% 8 minutes after sugammadex 2 mg kg(-1) i.v., and increased to 100% 3 minutes after additional 1 mg x kg(-1). Intraocular pressure stayed below 20 mmHg during the intervention. We could achieve full reversal of neuromuscular blockade and suppress increase in intraocular pressure with use of sugammadex.     

A case of fulminant hepatitis after reexposure to halothane six years later

We reported a case of halothane-induced fulminant hepatitis with acute renal failure which developed 6 days after reexposure to halothane. The patient was a 58-year-old female. She had a history of liver dysfunction after exposure to halothane 6 years previously. She had surgical treatment of clubfoot under halothane anesthesia in other hospital. Preoperative physical examination and laboratory data were normal. On the 6th post-operative day she abruptly developed high fever and general fatigue. Next day, she was transferred to our hospital. At admission, fulminant hepatitis complicated with acute renal failure was diagnosed with severe liver and renal damage. She was immediately treated with plasma exchange, glucose-insulin therapy, and hemodialysis. Serum transaminase level returned to normal value within a week. However, despite repeated hemodialysis, renal function did not improve, and she died of P. aeruginosa sepsis on 28th day after the operation. It may be suggested that in this patient hypersensitivity to halothane has persisted during the six years.     

A case of monoplegia from conversion disorder after spinal anesthesia

Neurological complications related to spinal anesthesia are exceptional, but their consequences are serious. We report a case of conversion disorder, which was initially diagnosed as monoplegia caused by spinal anesthesia. The patient was a 36-year-old, 88 kg woman with a history of psychogenic aphonia. She underwent plastic surgery for both toes under spinal anesthesia. On the following day, her left leg remained paralyzed with loss of sensation below the knee level. She practiced walking according to rehabilitation program, but paralysis became worse gradually. As the hospitalization was prolonged, she refused to be discharged from the hospital and began to demand the compensation. Her symptoms had not been correlated with the correct anatomical patterns of neurological deficit. The reflexes and muscle's tonus were normal and EMG gave normal findings. The result of neurological diagnosis, confirmed the diagnosis of conversion disorder causing her monoplegia because she was under psychic stressful circumstances from her family. Conversion disorder as a cause of monoplegia after surgery under spinal anesthesia should be kept in mind.     

Dyspnea attack due to hysteria after general anesthesia

A 30-year-old female was scheduled for an expander insertion of the breast under local anesthesia. Thirty minutes after infiltration anesthesia with lidocaine and bupivacaine mixture, she suffered from dyspnea. She was intubated and transferred to our hospital. As her vital signs were stable and consciousness was clear, she was extubated in the emergency room. However, she was reintubated at night and ventilated mechanically for two days. Three months later, breast expander insertion was performed under general anesthesia. After extubation, dyspnea attack occurred and midazolam was injected. Seven months later, the reconstruction of TRAM flap was performed under general anesthesia and continuous subcutaneous injection of morphine was used for the postoperative analgesia. After extubation, she was sedated deeply and dyspnea attack did not occur. A month later, she was scheduled for the debridment and the resuture. Then, dyspnea attack occurred in the ward at night. The apnea monitor was attached to her in recovery room after extubation following the operation of debridment and resuture. Dyspnea attack appeared and was diminished with midazolam injection. We diagnosed her as hysteria with CMI and MMPI psychologic tests.     

Cesarean section in a mother with uncorrected congenital coronary to pulmonary artery fistula

PURPOSE: We report a case of a 33 yr old woman with pulmonary hypertension secondary to uncorrected right coronary artery to pulmonary artery fistula who underwent two successful operative deliveries under general anesthesia. CLINICAL FEATURES: This woman underwent an emergency Caesarean section at 32 wk gestation because she presented in NYHA Class IV, heart failure and premature labour. She did not have antenatal follow-up. For her second pregnancy, she was managed from the first trimester of pregnancy by the cardiologist, obstetrician and anesthesiologist. She received oral furosemide and digoxin from eight weeks gestation. Pregnancy was managed to term before she progressed to NYHA Class IV and cardiac failure at 37 wk gestation. She had a Caesarean section under general anesthesia. She received rapid sequence induction of anesthesia and tracheal intubation with 0.1 mg x kg(-1) etomidate, 2 mg x kg(-1) succinylcholine and maintenance with nitrous oxide 50% in oxygen, isoflurane 1% and 0.1 mg x kg(-1) vecuronium. Fentanyl, 2 microg x kg(-1) helped to obtund the hypertensive response to intubation. Analgesia was provided with 1 mg x kg(-1) morphine. Glyceryl trinitrate infusion, 10-30 microg x min(-1) was used in addition to the anti-heart failure therapy. End-tidal capnography, electrocardiogram, pulse oximetry, continuous arterial blood pressure and pulmonary arterial catheter provided hemodynamic monitoring. The lungs were mechanically ventilated for 24 hr postoperatively. She received anti-heart failure therapy which she continued after discharge. She was NYHA class II upon discharge. She defaulted from further follow-up. CONCLUSION: Although the literature advocates, in this situation, controlled vaginal delivery utilising epidural analgesia, we describe the successful outcome for operative delivery under general anesthesia in a patient with secondary pulmonary hypertension and heart failure.     

Ketorolac-induced bronchospasm in an aspirin-intolerant patient.

A patient, in her mid-twenties, presented with "severe polypoid sinusitis" for sphenoethmoidectomy under general anesthesia. Upon preoperative medical evaluation, it was discovered that she was "allergic" to aspirin and suffered from stress-induced asthma. Before induction of anesthesia, the patient was administered intravenous hydrocortisone and two puffs of her albuterol inhaler to prevent a possible bronchospasm due to stress of the surgery or irritation from the endotracheal tube or other stimuli. The patient was maintained throughout the case with an inhalation anesthetic for its bronchodilatory effect. The surgery proceeded unremarkably, and the patient was then administered ketorolac tromethamine for postoperative pain. After an awake extubation, the patient was transferred to the postanesthesia care unit (PACU) for further monitoring. After 15 min in the PACU, the patient claimed having difficulty breathing. She was then administered terbutaline to produce bronchodilation, but her condition did not improve. Shortly thereafter, aminophylline, midazolam, and methylprednisolone were also administered intravenously. Meanwhile, the patient had to be reintubated and placed on ventilator support with heavy sedation. At this point, it was discovered that ketorolac may have been the cause of this response. Although the patient's condition began to improve, the histamine H1- and H2-receptor blockers diphenhydramine and ranitidine were coadministered. When the patient's condition returned toward normal, she was extubated. The patient's breathing continued to improve. Thereafter, she was transferred to an overnight observation bed and later dismissed to return home. The patient was advised of the episode and warned against future intake of other nonsteroidal antiinflammatory drugs.     

Case report: Rhabdomyolysis in morbidly obese patients: anesthetic considerations

Purpose

We report the presentation and management of rhabdomyolysis involving shoulder girdle and upper arm muscles in a morbidly obese patient after prolonged laparoscopic surgery.

Clinical features

A 41-yr-old morbidly obese woman presented for laparoscopic abdominal hysterectomy. She had hypertension and type II diabetes which were controlled on regular medications. She also had obstructive sleep apnea. Her clinical examination and investigations revealed no abnormality except morbid obesity (body mass index 54 kg·m^-2) and left ventricular hypertrophy on transthoracic echocardiogram. Standard general anesthesia was administered under baseline non-invasive monitors. Succinylcholine was used to secure the airway during anesthetic induction. Surgery was performed with the patient positioned with a 15° head-down tilt, and it took six hours to complete the procedure as technical difficulty was encountered due to her body habitus. Her trachea was extubated and she was transferred to the postanesthetic care unit (PACU) without incident. In the PACU, the patient complained of severe bilateral arm pain and weakness an hour after surgery. On physical examination, she exhibited limited movement of her arms against gravity while complaining of tenderness in her shoulder girdle muscles and both arms. Clinical suspicion of rhabdomyolysis based on her signs and symptoms was confirmed by an elevated serum creatinine kinase (CK) of 18,392 IU·L^-1 and serum potassium of 5.3 mmol·L^-1. Intravenous crystalloids and mannitol were administered for 24 hr for renal protection, and her clinical symptoms and serum CK levels improved over seven days. The patient was discharged to home on the tenth postoperative day, and she continued to improve over the three-month follow-up period.

Conclusions

Morbidly obese patients who undergo prolonged surgery are at risk for rhabdomyolysis, and early diagnosis and therapy are required to prevent severe complications.     

Hemothorax following intraabdominal bleeding due to pedicle torsion of ovarian tumor via a small pore in the diaphragm: report of a case

On February 25, 2004, 59-year-old woman visited a local clinic due to lower abdominal pain. On February 28, she was admitted to the clinic due to severe abdominal pain. Computed tomography (CT) showed a mass in the lower abdomen and plural effusion and athelectasis of the right lung. She had severe anemia (Hb 6.9 g/dl). On March 1, she was transferred to our hospital. Pleural fluid was revealed to be sanguineous by thoracentasis. She underwent thoracotomy on the day of admission. There was no source of bleeding in the pleural space. A small pore, 3 mm in diameter, was found in the tendinous portion of the diaphragm. An influx of bloody fluid from the abdomen via the pore caused hemothorax. Laparotomy was performed, followed by closure of the pore using direct suture. The origin of the abdominal bleeding was pedicle torsion of the right ovarian tumor. Seven months after surgery she was uneventful with no pleural effusion.     

Anesthetic management of three patients with myotonic dystrophy in a family

Case-1: A 24-year-old woman was admitted because of pressing hydramnion. She was treated by ritodrine hydrochlorides leading to rhabdomyolysis, and she was diagnosed as myotonic dystrophy. She underwent cesarean section because of urgent premature birth. The surgery was performed with spinal anesthesia using tetracaine. Case-2: A 1-year-old boy, the son of Case 1, underwent orchiopexy. He showed respiratory distress at birth and needed respiratory support for 140 days. The surgery was performed under general anesthesia combined with caudal anesthesia. Anesthesia was induced with nitrous oxide-oxygen-sevoflurane. He was intubated without muscle relaxants. Since he recovered consciousness soon after the surgery, he was extubated and returned to the ward. Case-3: A 30-year-old woman, the sister of Case 1, underwent tonsillectomy. At the age of 27 she underwent salpingectomy under general anesthesia with nitrous oxide-oxygen-halothane, after which she was diagnosed as myotonic dystrophy. She was anesthetized with propofol and fentanyl. Because severity of the myotonic dystrophy varies among the patients, the strategy for anesthesia should be planned on each patient. Generally speaking, regional anesthesia including spinal and epidural anesthesia is preferable.     

Chronic spinal epidural abscess (author's transl)]

A case of 58 year old female with chronic spinal epidural abscess demonstrating rapid progression of complete spinal cord paralysis without remarkable recovery by laminectomy was reported. Patient had a large subcutaneous abscess on left back, ten years ago. Three months before admission she fell down from stairs and had a compression fracture on the seventh thoracic vertebra. She has been troubled with slight spinal ache and left lower back pain since the fall accident. One month before admission she suddenly noted severe lower back pain with radiation to left side and the pain became more severe. Three weeks after she noted fecal retention without urinary retention. Five days before admission she noted gait disturbance accompanied by numbness of both foots. Three days later she developed inability to urinate and the same day, over the coure of a few hours, she became total paraplegia and anesthesia below the waist. On admission neurological examination and myelography disclosed complete spinal subarachnoid block with flaccid total paraplegia and anesthesia below the lower chest. The clinical diagnosis was spinal epidural mass lesion, probably neoplasm. Laminectomy from Th-6 through Th-9 was performed the next day: three days after complete paralysis. The epidural abscess included pus and soft granulation tissue was found and totally removed. Staphylococcus aureus sensitive to penicillin, chloramphenicol etc. was isolated on becteriologic culture. On seven months after operation, sensory and deep reflexes were considrable improved, but she remained paraplegic without sphincter control. Dicussion were made on the incidence, pathogenesis.     

Left-sided adult Bochdalek hernia with right lung cancer; report of a case

Bochdalek hernia is a common congenital anomaly in neonatal patients with risky respiratory distress and high mortarity, but can be seen in adults. A case of left-sided adult Bochdalek hernia with right lung cancer is reported. A 71-year-old female had been performed radition therapy for lung cancer in the right lower lobe. She was admitted to our hospital due to advanced lung cancer and pneumonia. On the 7th day after admission, she felt dyspnea and abdominal distention due to herniation of the stomach through the posterolateral defect of the diaphragma into the left hemithorax. Her condition did not allow us a radical surgery of Bochdalek hernia, so that we performed a palliative surgery, that is reduction of the stomach and gastrostomy. After surgery, her respiratory distress was lightened and she came to be able to ingest. She was less uncomfortable until she died due to progression of the lung cancer.     

Complications of hysteroscopical myomectomy: a report of two cases

Hysteroscopical myomectomy has recently become popular in Japan. We present two patients who developed water intoxication and air embolism during surgery. [Case 1] Hysteroscopical myomectomy was performed under general anesthesia in a 37-yr-old woman (ASA I). Three hours after the start of the surgery, the patient's serum sodium concentration dropped to 118 mEq.l-1. She was treated with furosemide and recovered without sequelae. [Case 2] A 39-yr-old woman (ASA I) was scheduled to have hysteroscopical myomectomy under spinal and epidural anesthesia. Forty-five minutes after the start of the surgery, the patient complained of severe back pain, her blood pressure decreasing to 40 mmHg, SpO2 decreased to 80%, and ECG showed atrial fibrillation. After administration of ephedrine 5 mg, she recovered within 20 min. No abnormality was observed in echocardiogram, although some negative spots were detectable in a lung scintigraphy. She was discharged without sequelae. The hysteroscopical procedure is considered a non-invasive surgery, but the cases presented here emphasize the necessity for close attention to complications, especially pulmonary embolism.     

Spinal anesthesia for preterm infants undergoing inguinal hernia repair

HYPOTHESES: Use of spinal anesthesia is safe and effective in an outpatient population of preterm infants undergoing inguinal hernia repair (IHR) and eliminates routine postoperative hospital admission for apnea monitoring. METHODS: From October 1982 through October 1997, all preterm (gestational age [GA], < or =37 weeks), high-risk (preterm infants whose postconceptual age at surgery [PCAS] is <60 weeks) infants undergoing IHR with spinal anesthesia were studied prospectively. No exclusions were made for preexisting conditions. Elective IHRs and incarcerated hernias were both considered. A postoperative apnea rate was calculated and compared with published postoperative apnea rates in preterm infants after receiving general anesthesia. RESULTS: For 269 IHRs performed, 262 spinal anesthetic placements (97.3%) were successful in 259 infants; 246 placements were achieved on the first attempt and 16 on the second. The mean GA was 32 weeks (GA range, 24-37 weeks); mean PCAS, 43.7 weeks (PCAS range, 33.4-59.3 weeks); and mean birth weight, 1688 g (weight range, 540-3950 g). Two hundred six patients (78.6 %) did not require supplemental anesthesia; 56 (21.4%) did: 34 received intravenous anesthesia; 6, general; 12, local; and 4, other regional. One hundred fifty-three infants had a history of apnea. Thirteen episodes of apnea were noted in 13 infants (4.9%) following the 262 procedures; all 13 were inpatients undergoing concomitant therapy for apnea (mean GA, 28 weeks; PCAS, 42.9 weeks). Four of these infants received supplemental anesthesia. This apnea rate is significantly lower than the published rate (10%-30%) (P = .01). One hundred three infants underwent IHR on an outpatient basis, 39 of whom had a history of apnea. None of these developed apnea postoperatively. The mean birth weight of this group was 2091 g (weight range, 710-3693 g); mean GA, 33 weeks (GA range, 25-37 weeks); and mean PCAS, 44.3 weeks (PCAS range, 35.4-59.2 weeks). All 103 patients were discharged home the day of surgery. Average time from room entry to incision was 26.3 minutes, which is similar to anesthesia induction time for patients receiving general anesthesia. Average time from bandaging to leaving room was 1 minute, less than usual time for patients receiving general anesthesia. CONCLUSIONS: Spinal anesthesia is safe, effective, and eliminates the need for postoperative hospital admission in an outpatient population of preterm infants undergoing IHR. This results in considerable cost savings without compromising quality of care.     

A case of spinal cord glioblastoma multiforme]

A 35-year-old woman was admitted to our hospital with a 3 month history of progressive paraparesis and impairment of bowel and bladder function. MRI suggested a malignant glioma at the level of T9 to L1. Laminectomy and subtotal removal of the tumor was performed. The surgical specimen was a glioblastoma multiforme. An aggressive adjuvant therapy was scheduled to prevent rapid local regrowth and leptomeningeal dissemination. Radiotherapy with a total dose of 65Gy was delivered with chemotherapy including ACNU (2mg/kg) and vincristine (0.2mg/kg). Lymphokine-activated killer (LAK) cells were given intrathecally with a total dose of 1.6 x 10(9) LAK cells with 3 x 10(4) units of IL-2. MRI taken 6 months after surgery revealed no residual tumor, and no malignant cell was detected in the patient's CSF. After physiotherapy, she became able to walk with a stick and was discharged. Chemotherapy (ACNU 2mg/kg/8 weeks) had been further continued for 2 years. She did well until 14 months after surgery, when paraparesis recurred and rapidly progressed to completism. MRI revealed a spinal cord swelling with marked edema, suggesting delayed radiation necrosis. Two years after surgery, MRI showed a marked atrophy of the spinal cord, and no residual tumor. But 3 years after surgery, a round tumor at the level of T11 and T12 was revealed on MRI, and she was admitted to our hospital again. A spinal cord amputation was performed, and the tumor was totally removed without worsening her neurological symptoms. Surgical specimen of the tumor was glioblastoma multiforme again.(ABSTRACT TRUNCATED AT 250 WORDS)     

Retroperitoneal emphysema during total hip replacement

A 55-year-old woman with rheumatic arthritis was scheduled for total hip replacement. The procedure was performed under combined spinal and epidural anesthesia. Intraoperatively, the part of acetabular roof was cracked by reaming the region but she did not complain of any symptom. However, during pulse irrigation she complained of abdominal pain. After the operation, abdominal distension was noticed and retroperitoneal emphysema was disclosed. She was managed in a ward without problems postoperatively.     

Deep neck infection following endotracheal intubation]

A 71-year-old woman was transferred to Kushiro City General Hospital because of fever, sore throat, diffuse neck swelling and dyspnea. She had received right mastectomy for breast cancer under general anesthesia 6 days before the admission. The lateral X-ray film of the neck revealed abscess in the retropharyngeal space and the retroesophageal space. CT scan revealed mediastinitis. Next day she received neck dissection for drainage of the abscess under general anesthesia. Although the posterior pharyngeal wall was swollen, endo-tracheal intubation was not difficult. Brown tinged and purplish pus was aspirated from the interspace of carotid sheath and trachea, the retropharyngeal space, and the superior mediastinal space. The infected site was irrigated with a lot of peroxide and saline and draining tubes were placed in each interspace. Tracheostomy was not done but the patient was admitted to the ICU with her trachea intubated. The day after operation, she was extubated. Three days after the operation chest X-ray revealed pyothorax and chest tube was inserted for drainage. Seven days after the operation she was transferred to the ENT ward. Thereafter her recovery course was uneventful. It seems that the deep neck infection was probably caused by the injury on endotracheal intubation at the first operation in this case. Although this patient was cured of mediastinitis following deep neck infection, which is still lethal, early diagnosis and surgical drainage of the abscess are necessary.     

Comatose patient with neuroleptic malignant syndrome brought by ambulance

A 27-year-old woman with schizophrenia showed signs of neuroleptic malignant syndrome with disturbed consciousness, high fever, muscle rigidity, and autonomic dysfunction (including tachycardia and enhancement of saliva secretion). Since the age of 15, she had been treated at a local psychiatric clinic with a diagnosis of schizophrenia. On the day she was brought to the emergency room, she was asleep in the morning, but tachycardia was observed in the evening in the absence of consciousness. The patient was brought to our hospital by ambulance. It was revealed that she had taken a massive dose of chlorpromazine hydrochloride in the morning on the same day. On arrival, the Japan coma scale, pulse, respiratory rate, body temperature, and Sp(O2) were 300, 114 beats x min(-1), 26 breaths x min(-1), 39.0 degrees, and 91% (room air), respectively. The CPK level was 1,776 IU x l(-1). Sp(O2), bilateral pneumonia, and right atelectasis improved 2 hours after admission. Endotracheal intubation was performed for artificial respiration. Salivation, marked sweating, and rigidity of the limbs were noted. Under a diagnosis of neuroleptic malignant syndrome, dantrolene was administered. For pneumonia, ceftriaxone and pazufloxacin were administered. The consciousness became clear 2 days after admission. The patient was discharged 10 days after admission.     

Anesthesia for cesarean section in a parturient taking risperidone and haloperidol

We report a case of anesthesia for cesarean section in a schizophrenic patient. Her psychiatric symptoms were well controlled with low doses of risperidone until 35 weeks' gestation, when she suddenly developed psychotic manifestations. Risperidone 6 mg x day(-1) and haloperidol 12 mg x day(-1) PO were given for 3 weeks before delivery. Elective cesarean section was performed under spinal anesthesia at 38 weeks. The parturient showed good psychiatric condition during and after the surgery. The neonate did not show any symptoms which antipsychotics could have caused. Maternal and umbilical blood concentrations of risperidone and haloperidol are reported.     

Rupture of a splenic artery aneurysm into the pancreatic duct. Case report

A 71-year-old woman was admitted to a local hospital with abdominal pain and repeated haematemeses and melaena. Plain X-ray of the abdomen showed a cystic mass with a calcified wall behind the stomach. No bleeding point in the stomach or duodenum was found at gastroscopy. Over a period of 28 days she had five episodes of gastrointestinal haemorrhage with no drop in blood pressure. She was transferred to the regional hospital 26 days after admission. Angiography showed a splenic artery aneurysm 5 x 10 cm, which at operation was found to have ruptured into the pancreatic duct. The aneurysm, the tail of the pancreas and the spleen were removed, and she made an uneventful recovery.     

Spinal cord stimulation for a woman with complex regional pain syndrome who wished to get pregnant

A woman with complex regional pain syndrome (CRPS) in the right lower extremity who wished to discontinue medications to get pregnant underwent implantation of a spinal cord stimulation system (SCS). An electrode lead was placed at Th_10–11 in the epidural space, accessed via the L_2–3 interspace with a paramedian approach, and a pulse generator was implanted in the left buttock. She kept the SCS on 24 h a day. After she had experienced several chemical abortions, finally she got pregnant via artificial insemination. She had an uneventful delivery of a healthy baby by cesarean resection under spinal anesthesia. In a patient with CRPS who has an implanted SCS system and wishes to get pregnant, the electrode lead into the low thoracic epidural space should be accessed via the high lumbar intervertebral space in consideration of a future requirement for spinal or epidural anesthesia for cesarean section. The generator should be placed in the buttock to prevent impairment of the SCS system being caused by the enlarged abdomen during pregnancy. Although we were apprehensive of adverse effects owing to the electromagnetic field force and change of blood flow in the pelvic viscera, our patient had a successful delivery. SCS is a favorable option for patients with CRPS who wish to get pregnant.
