Preemptive analgesia in laparoscopic cholecystectomy: a randomized controlled study.

In pain control after laparoscopic cholecystectomy, subhepatic administration of bupivacaine immediately after the creation of pneumoperitoneum has been shown to be more effective than administration before the withdrawal of the trocars. We aimed to investigate the effect of intraperitoneal bupivacaine administration to the subhepatic area before the creation of the pneumoperitoneum. Eighty patients undergoing elective laparoscopic cholecystectomy under general anesthesia were included in a prospective, randomized study. Patients received 20 mL of 0.5% bupivacaine in the subhepatic area just after intubation, before pneumoperitoneum (group 1), immediately after the creation of the pneumoperitoneum (group 2), just before the removal of the trocars (group 3), or received no local anesthetic (group 4). The degree of the postoperative pain was assessed at 0, 4, 8, 12, and 24 hours after the surgery. The consumption of analgesics (diclofenac sodium) was also recorded. The pain scores and analgesic consumption did not differ among groups 1, 3, and 4. The pain scores of group 2 were lower at each time point compared to the other groups (P < 0.001). Postoperative analgesic consumption in group 2 was reduced compared to the other groups (23.4 +/- 35.9 mg vs. 80.0 +/- 66.3 mg, P = 0.005 [group 1], 69.6 +/- 62.2 mg, P = 0.026 [group 3], and 70.0 +/- 59.9 mg, P = 0.022 [group 4]). The subhepatic infiltration of 20 mL of 0.5% bupivacaine offers good postoperative analgesia when applied just after the creation of the pneumoperitoneum, not before the pneumoperitoneum or after the termination of the pneumoperitoneum.

Effects of fentanyl on pain and hemodynamic response after retrobulbar block in patients having phacoemulsification.

PURPOSE: To determine the effects of systemic fentanyl analgesia in preventing the pain related to the administration of retrobulbar anesthesia and cataract surgery. SETTING: Departments of Ophthalmology and Anesthesiology, School of Medicine, Kocatepe University, Afyon, Turkey. METHODS: One hundred twenty patients with American Society of Anesthesiologists physical status I to III scheduled for cataract surgery were evaluated in a single-blind randomized study. Patients with a history of hypertension, hyperthyroidism, or neurologic or psychiatric disorders were excluded. In the study (fentanyl) group, an intravenous bolus of fentanyl 2 microg/kg was slowly given 5 minutes before retrobulbar anesthesia was administered. In the control group, fentanyl was not given. There were 60 patients in each group. Demographic data were not statistically different between the 2 groups. The intensity of pain during injection and intraoperatively was measured by verbal pain scores. Hemodynamic stability was assessed by the heart rate (HR) and mean arterial pressure (MAP). End-tidal carbon dioxide concentrations and oxygen saturations were also recorded. RESULTS: The changes in HR and MAP at 0, 10, 20, and 30 minutes were statistically significant between the fentanyl and control groups (P<.05). Fentanyl reduced pain scores significantly at all evaluations (P<.05). CONCLUSION: The results suggest that fentanyl preemptively decreases injection and intraoperative hyperalgesia and provides hemodynamic stability without affecting patient cooperation, resulting in cataract surgery with retrobulbar anesthesia that is comfortable for both surgeon and patient.

Detection of fungi spectrum in industrial and home bakeries and determinated fungal allergy with skin prick test.

Airborne fungal pathogens such as Penicillium, Aspergillus, Cladosporium, Trichophyton, and Alternaria may cause health problems. In this research, the fungal flora at different bakeries and their potential allergenic effects on the workers were investigated. We investigated 148 workers at 17 industrial type bakeries and 62 workers at 17 home type bakeries in Afyon. Our study was performed in two different seasons and climates, between January 2004 and June 2004. Fungal flora was detected by using Petri-dish method. In the winter, Penicillium was the dominant genus, while Cladosporium was the dominant genus during the summer, in both types of bakeries. The allergenic properties of dominant culturable fungi on workers involved in the bakeries were determined with the skin-prick test. It was found that with workers in the industrial type bakeries, the most common skin test positivity was caused by Penicillium. In the other hand, the skin test positivity, performed on workers in the home type bakeries, was equally caused by Penicillium, Trichophyton and Aspergillus.
