Delayed Obstruction of Endotracheal Tube by Previously Aspirated Foreign Body: A Case Report / 대한구급학회지

Acute airway obstruction during endotracheal intubation status is embarrassing and critical situation which requires early diagnosis and immediate management. Endotracheal tube obstruction with foreign body is rare but a variety of objects have been reported. We present a case of endotracheal tube obstruction as a result of previous aspirated foreign body that moved from the bronchial tree into the endobroncheal tube.

Significance of Infrared Thermal Imaging in Herpes Zoster Patients / 대한마취과학회지

BACKGROUND: Herpetic disorders cause pain and skin lesion. So, asymmetric temperature of both sides of the involving dermatome has been reported in thermogram. This study examined the usefulness of infrared thermography for a predictor of post-herpetic neuralgia (PHN). METHODS: Patients with acute herpes zoster who underwent nerve block were randomly selected. Biographic data, including age, gender and times of onset of the skin lesions, development of PHN, combined diseases were recorded. Infrared thermography was performed and subjective pain severity, dysesthesia and allodynia, skin lesion size were assessed. RESULTS: The temperature differences between the lesion site and the contralateral site at lateral and posterior were significantly correlated with lesion size (P 0.05). PHN was correlated with skin lesion size and infrared thermal imaging (P < 0.01). CONCLUSIONS: Infrared thermal imaging cannot demonstrate subjective pain objectively in herpes zoster. Short duration showed high temperature on the lesion sites compared to the contralateral sites. The patients with big skin lesions developed PHN more. The PHN can be predicted by the infrared thermal imaging as low temperature on the lesion site compared to the contralateral site.

Control of Postinguinal Herniorrhaphy Pain in Children / 대한마취과학회지

BACKGROUND: Postoperative pain control in children is an important problem for management but it was treated negligently. In the past, the pain was undertreated in children, even more in infant. In recent years, the importance of the pain control in children was emphasized but not enough, yet. This study was designed to evaluate the propriety of intraoperative intravenous medication technique and effectiveness of the fentanyl, ketorolac and ketamine for pain control following inguinal herniorrhaphy in pediatric patients. METHODS: Eighty children for inguinal herniorrhaphy under general anesthesia were divided into four groups. Group I received no analgesics as a control. Group II, III and IV were received intravenous fentanyl 1microgram/kg, ketorolac 1 mg/kg and ketamine 1 mg/kg respectively. Fentanyl and ketolorac were injected intravenously during the induction of anesthesia and ketamine was injected at the entrance of operating room. Emergence time and the degree of pain was evaluated. RESULTS: Our result showed that group II and group III had a lower pain score than that of the control group at the 5 min, 10 min, 20 min and 30 min in the recovery room (P <0.05), but no significant differences were found between the group I and group IV. The time interval from the end of operation to extubation was prolonged in the group II compared to the control group (P <0.05). But no significant differences were found between the three groups. CONCLUSIONS: We suggest that intravenous administration of analgesics has the propriety of the control of postinguinal herniorraphy pain in children. Intravenous administration of fentanyl 1microgram/kg and ketorolac 1 mg/kg during induction would be an easy, simple and effective means for relieving postinguinal herniorrhaphy pain in recovery room.
