[Postoperative analgesia for the laparoscopic cholecystectomy].

BACKGROUND: As laparoscopic cholecystectomy is assumed to be with less postoperative pain, it is managed only by general anesthesia during the surgery in our hospital. However, about 70 percent of cases needed the additional analgesic drugs after the operation. In addition, about 70 percent needed analgesic drugs within three hours after the operation, and it has been understood that early postoperative analgesia is insufficient. We focused on the ultrasound guided nerve block and used it to relieve postoperative pain after the laparoscopic cholecystectomy. METHODS: Forty three cases managed by the general anesthesia alone are compared with 9 cases managed with the nerve block of the trunk in for the laparoscopic cholecystectomy. RESULTS: Pain score early after the operation, the ratio of patient who used analgesic drug, and the frequency of its use are all decreased by performing the block. CONCLUSIONS: The use of ultrasound guided nervous block for the postoperative pain after laparoscopic cholecystectomy has been helpful, and excellent pain relief has been obtained.

[Anesthesia induction for patients with cervical spinal disease].

BACKGROUND: In the cases in which the flexibility of the patient's neck is limited, it is often difficult to achieve intubation. Fiberoptic intubation has been chosen for patients with arthroses. However, as it requires techniques, it has been difficult for inexperienced anesthesiologists. METHODS: Awake induction using AirWay Scope was performed for 8 patients with cervical spinal diseases. Midazolam, propofol or dexmedetomidine is selected as a sedative drug. RESULTS: Intubation was performed easily and safely without any complications in all cases. No patients had memories of intubation. CONCLUSIONS: Awake intubation using AirWay Scope for patients with cervical spinal diseases is a safe and useful anesthesia method. As dexmedetomidine causes no respiratory depression and can expect cooperation from patients, it may give safe and efficient sedation in awake intubation cases.

[Rosai-Dorfman disease accompanying hypertrophic cranial pachymeningitis with an early symptom of right peripheral facial palsy].

We experienced a rare case of sinus histiocytosis with massive lymphoadenopathy (Rosai-Dorfman disease) accompanying hypertrophic cranial pachymeningitis. The patient is a 64-year-old woman with an early symptom of rt. peripheral facial palsy. She had a 4-month history of headache with a 5-week history of numbness in the rt. supraorbital nerve area, and lost her weight by 10 kg in 2 months. She developed rt. trochlea nerve palsy and numbness in the lt. mandibular nerve area. Laboratory findings showed that ALP, LDH and CRP were higher than normal. Of CT, MRI and MRA, the images of her head were normal. However, the Gd-enhanced MRI only showed a diffuse pachymeningeal enhancement. After about 3 months from the onset of rt. peripheral facial palsy, she died of DIC of unknown etiology. As a result of examinations in anatomical pathology, she was diagnosed as having sinus histiocytosis with massive lymphoadenopathy (Rosai-Dorfman disease). There were a large number of histiocytes on the pachymeninx. These findings suggest that hypertrophic cranial pachymeningitis caused multiple cranial neuropathy. We emphasize that use of Gd-enhanced MRI in the early stage is important for diagnosis.
