Study for the discrepancy of arterial blood pressure in accordance with method, age, body part of measurement during general anesthesia using sevoflurane.

Background Many pieces of previous research on measuring blood pressure (BP) using different methods focused on the disparity in the results. However, none of them dealt with the disparity caused by the difference in age and inhalation anesthetics. We attempted to find the variance in accordance with age, body part, and measuring methods (invasive vs noninvasive) and also studied how sevoflurane influences BP as the operation progresses. Methods In sixty patients, we measured the arterial BP in the upper and lower limbs by noninvasive methods before inducing anesthesia. After induction, we used sevoflurane to maintain anesthesia, and injected catheters into the radial artery and dorsalis pedis artery to measure arterial pressure at every ten minute by both invasive and noninvasive methods. Results The patients who were 40 or older showed significantly higher values in the systolic BP than the patients younger than 40. The values of systolic and diastolic BP measured by a noninvasive oscillometric method were meaningfully higher than those measured by an invasive method. As the operations progressed, the lower limbs showed higher systolic pressure than the upper limbs regardless of measuring methods, whereas the opposite is true for diastolic pressure. Conclusions The values in the arterial BP were measured high by noninvasive method. Systolic BP were estimated significantly high in the older patients and in the lower leg. Due to the effect of sevoflurane, the diastolic BP in the lower limbs becomes lower than that of upper limbs regardless of measuring methods, as the operation progresses.

Tracheal intubation via esophagus in a patient with congenital tracheoesophageal fistula - A case report -

H type of congenital tracheoesophageal fistula (TEF) is rare, occurring approximately once in 100,000 births. The presentation of this anomaly in adults is indeed uncommon. We report a case of a 47-year-old male with congenital TEF dectected during epidural hematoma removal under general anesthesia. Intermittent disappearance of normal capnography, bubbling sound at substernal area, and air leakage at oral cavity observed during manually assisted ventilation, especially during inspiration. We observed a H-type of TEF and tracheal intubation via esophagus in chest CT after operation.

A comparison of cervical epidural analgesia and intravenous patient-controlled analgesia after mastectomy with immediate latissimus dorsi flap breast reconstruction

BACKGROUND Breast reconstruction following mastectomy has become increasingly popular in recent years. The purpose of this study was to compare the efficacy of cervical epidural patient-controlled analgesia (CEA) and intravenous patient-controlled analgesia (IV-PCA) for controlling the postoperative pain and the side effects after mastectomy with immediate Latissimus dorsi (LD) flap breast reconstruction. METHODS Sixty patients who were to undergo mastectomy with immediate LD flap breast reconstruction were randomly assigned to receive CEA [Group CEA, (n = 30), 0.15% ropivacaine + fentanyl 4 microg/ml] or IV-PCA [Group IV-PCA (n = 30) fentanyl 20 microg/kg + ketorolac 3 mg/kg] for postoperative pain control via a PCA pump (basal rate: 2 ml/h, bolus: 2 ml, lock out interval: 15 min) after their operation. Before general anesthesia, an epidural catheter was inserted at the cervical (C)7-thoracic (T)1 level in the patients of the CEA group. The resting visual analogue scale (VAS) for pain, the systolic blood pressure, the heart rate and the side effects were recorded for 48 hours after operation. RESULTS The VAS at rest was significantly lower in the CEA group than that in the IV-PCA group at 16 hours after surgery. The CEA group required less additional analgesics as compared with the group IV- PCA. There were no significant differences in the systolic blood pressure, the heart rate and the incidence of side effects between the two groups. CONCLUSIONS We conclude that cervical epidural analgesia, as compared with intravenous patient-controlled analgesia, provides effective pain control and it shows a similar incidence of side effects after mastectomy with immediate LD flap breast reconstruction.
