Clonidine caused bradycardia and hypotension and magnesium sulphate caused delayed recovery, but can be used as adjuvant agents with careful management.
Richmond agitation sedation scale levels significantly correlated with bispectral index values during dexmedetomidine sedation in critically ill patients requiring mechanical ventilation in the intensive care unit.
Exacerbation of chronic obstructive pulmonary disease (COPD) is one of the frequent causes of acute respiratory failure. In our study, we aimed to compare helmet with face mask in noninvasive mechanical ventilation (NIMV) on patients who had acute respiratory failure because of exacerbation of COPD in intensive care unit (ICU). Thirty patients, taken into ICU for exacerbation of COPD, were included in the study. Patients were divided into two groups as face mask group (Group Y) and helmet group (Group H). Appropriate mechanical ventilation settings were recorded after the starting period and NIMV was applied to patients continuously for two hours with these settings. Respiratory frequency (f), blood gas (PaO(2), PaCO(2), PH) and PaO(2)/FiO(2) values and hemodynamic data of all patients were recorded periodically. Compliance of patients were evaluated with patient tolerance scale (PTS). Duration of stay of the patients in ICU and complications were also noted. Demographic characteristics of patients, mechanical ventilator settings and hemodynamic data of the patients in the two groups were found to be similar (p>0.05). Frequency values measured during NIMV are also similar at all measurement times (p>0.05). It was determined that there was a remarkable decrease in respiratory frequency, in both groups after the application of NIMV (p< 0.001). There was no difference with respect to PaO(2), PH and PaO(2)/FiO(2) values at all measurement times, between groups (p> 0.05). PaCO(2) values in the beginning were similar in both groups but PaCO(2) measured at other measurement times for group H were statistically higher compared to the other group (p< 0.05). PTC score measured at during NIMV in group H were remarkably higher (p< 0.05). Helmet developed as an alternative to face mask has a better patient tolerance and accordingly in increases success rate in NIMV. But it must be keeping mind that the decrease in PaCO(2) value is slow with helmet.
This study investigated the possible local adverse effects of intra-articular administration of tenoxicam in the rat knee joint. A total of 50 rats were given 0.25 ml of a standard preparation of tenoxicam by injection into the right knee joint and 0.25 ml of 0.9% saline solution by injection into the left knee joint as a control. Groups of 10 rats were killed 24 h, 48 h, 7 days, 14 days and 21 days after tenoxicam administration. Two rats were sham operated; one was killed on the first day and the other on the second day after this procedure. All the joints were prepared and sectioned for histological examination. Tissue loss and oedema were observed in the specimens obtained 24 h and 48 h after treatment with tenoxicam. No pathological changes were observed in the 7-day, 14-day and 21-day specimens, or in the control joints. Caution should be exercised when using intra-articular tenoxicam for post-operative analgesia.
Introduction: The aim of this study is to compare two different anesthetic techniques in radical cystectomy with regard to blood loss, transfusional requirements, intraoperative complications and the quality of analgesia. Materials and Methods: 50 patients scheduled for radical cystectomy were randomized to two groups: group GA – general anesthesia, n = 25 and group CEGA – combined epidural and general anesthesia. The patients were monitored and hemodynamic changes, intraoperative bleeding, transfusional requirements, quality of analgesia and postoperative complications were evaluated. Results: There were no significant differences between the demographic characteristics of the two groups. Intraoperative bleeding which was 874.8 ± 190.7 ml in the CEGA group and 1,248.3 ± 343.4 ml in the GA group was statistically different (p < 0.05). Significantly more intraoperative blood transfusions in terms of units were required in the GA group. Analgesia was better in the CEGA group, with VAS values at 0, 1, 2, 4, 6, 12 and 24 h significantly (p < 0.05) lower than those observed in the GA group. No significant differences in intraoperative hemodynamic parameters or postoperative complications were noted between the two groups. Conclusions: Statistically significant differences in intraoperative bleeding were observed between the two groups: CEGA provides lower intraoperative bleeding and a better postoperative analgesia. Major operations such as radical cystectomy, which also is associated with considerable blood loss, a combination of general and epidural anesthesia may allow for less blood loss, with a better postoperative analgesia and without any increase in complications.
Addition of preoperative or postoperative rectal paracetamol in the doses used did not show an effect on the duration and intensity of postoperative analgesia obtained by caudal bupivacaine.
