ABSTRACT

BACKGROUND Caudal block is widely regarded as the top choice for multimodal analgesia in children undergoing urological surgeries, particularly circumcision. This study investigates the efficacy of caudal block and the necessity of rescue analgesia in circumcision surgeries. MATERIAL AND METHODS A prospective, single-blind study was conducted at Ordu University Training and Research Hospital from December 1, 2022, to July 1, 2023. The study randomly divided ASA class I-II children aged 1-12 years into 3 groups for circumcision surgery. Group C received only caudal block. Group CP received caudal block with 10 mg/kg intravenous paracetamol. Group CM received caudal block with 1 mg/kg intravenous meperidine. In each case, a caudal block was administered using 0.5 ml/kg of 0.125% bupivacaine under ultrasound guidance. The primary outcome of the study was total analgesic consumption; the secondary outcomes were pain scores and time to first analgesic administration. Pain severity was evaluated using FLACC and Wong-Baker scores at 0, 1, 4, and 24 h. RESULTS A total of 120 patients, 40 patients in each group, were included in the study. A significant difference was detected among all 3 groups in the Wong-Baker pain score (24th hour) (P<0.001). The FLACC and Wong-Baker pain scores did not differ significantly in the other time frames. The time of the first rescue analgesia and the total amount of analgesic taken in the first 24 h were the same for both groups (P=0.408 and P=0.238). CONCLUSIONS The addition of paracetamol or meperidine to caudal block does not enhance the quality of analgesia.

ABSTRACT

ACKGROUND: There are very few studies in the literature focusing on whether dexmedetomidine exerts a protective effect on colistin nephrotoxicity. Our study aims to investigate the nephroprotective effect of dexmedetomidine in an experimental model of nephrotoxicity in rats. METHODS: The control group was administered saline (SF) intraperitoneally twice a day. The colistin group received an intraperitoneal (ip) injection of 10 mg/kg of colistin twice a day. The DX10 group received 10 mg/kg of colistin 20 minutes after the intraperitoneal injection of 10 mcg/kg of dexmedetomidine. The DX20 group received 10 mg/kg of colistin 20 minutes after the intraperitoneal injection of 20 mcg/kg of dexmedetomidine. Applications were continued for 7 days, twice a day. All rats were sacrificed on the 8th day after blood and kidney tissue samples were taken. BUN, Creatine, KIM-1 and Endothelin-1 were studied in blood samples. RESULTS: There was a significant difference in the median values of Urea, BUN and Creatine between the groups (p<0.001, p<0.001, p<0.001, respectively). There was a significant difference in the median values of KIM-1 and Endothelin-1 between the groups (p=0.009, p=0.001, respectively). A significant difference was observed between the histopathological scores of the groups (p<0.001). CONCLUSION: Dexmedetomidine significantly decreased the elevated levels of BUN, Creatinine, KIM-1, and Endothelin-1 induced by colistin. Dexmedetomidine, at both doses, histopathologically prevented apoptosis and reduced the number of necrotic cells in the kidneys. Dexmedetomidine provides renoprotective effects, therefore it is a valuable sedation agent for clinicians working in intensive care units (Tab. 2, Fig. 4, Ref. 19).

ABSTRACT

OBJECTIVE: To evaluate the sedative efficacy and effects on early period cognitive function of premedication in endoscopic retrograde cholangiopancreatography (ERCP). METHODS: Forty patients (18-70 years; American Society of Anesthesiology risk category I-III) undergoing elective ERCP were randomized to receive oral premedication with 0.15 mg/kg midazolam or 1 mg/kg tramadol. Cognitive function was determined by mini-mental test (MMT). Target scores for effective sedation were determined as a Bispectral index score of 70-90 and modified Ramsay Sedation Scale score (mRSS) of 2-4. RESULTS: Global MMT score was not significantly different between treatment groups at 60 min post-ERCP. A significant deterioration in the MMT subcategory of recall was determined in with midazolam versus tramadol. Level of sedation (mRSS) was higher in with midazolam compared with tramadol reaching statistical significance at 30 min after drug administration. CONCLUSIONS: Although more effective sedation was obtained with midazolam in patients undergoing ERCP, there was a dysfunction in memory recall. It was concluded, however, that early cognitive functions were generally preserved with both drugs.

ABSTRACT

PURPOSE: To compare the effects of different anesthesia techniques on tourniquet-related ischemia-reperfusion by measuring the levels of malondialdehyde (MDA), ischemia-modified albumin (IMA) and neuromuscular side effects. METHODS: Sixty ASAI-II patients undergoing arthroscopic knee surgery were randomised to three groups. In Group S, intrathecal anesthesia was administered using levobupivacaine. Anesthesia was induced and maintained with sevoflurane in Group I and TIVA with propofol in Group T. Blood samples were obtained before the induction of anesthesia (t1), 30 min after tourniquet inflation (t2), immediately before (t3), and 5 min (t4), 15 min (t5), 30 min (t 6), 1 h (t7), 2 h (t8), and 6 h (t9) after tourniquet release. RESULTS: MDA and IMA levels increased significantly compared with baseline values in Group S at t2-t 9 and t2-t7. MDA levels in Group T and Group I were significantly lower than those in Group S at t2-t8 and t2-t9. IMA levels in Group T were significantly lower than those in Group S at t2-t7. Postoperatively, a temporary 1/5 loss of strength in dorsiflexion of the ankle was observed in 3 patients in Group S and 1 in Group I. CONCLUSIONS: TIVA with propofol can make a positive contribution in tourniquet-related ischemia-reperfusion.

ABSTRACT

BACKGROUND AND OBJECTIVE: The aim of this study was to compare the effects of propofol and N-acetyl cysteine (NAC) on tourniquet-induced ischaemia-reperfusion injury by determining malonyldialdehyde, ischaemia-modified albumin, lactate, blood gas and haemodynamic levels in arthroscopic knee surgery. METHODS: Sixty ASA I or II patients were randomized into three groups. Intrathecal anaesthesia was administered using 0.5% heavy bupivacaine in all patients. In group P, propofol was administered in a 0.2 mg kg(-1) bolus, followed by infusion at a rate of 2 mg kg(-1) h(-1); in group NAC, NAC was administered as an infusion at a rate of 5 mg kg(-1) h(-1), and, in group C (the control group), an equal volume of isotonic saline was administered to patients until 30 min after reperfusion. Blood samplings were obtained immediately before intrathecal anaesthesia (t1), 1 min before tourniquet release (t2), 5 min after tourniquet release (t3) and 30 min after tourniquet release (t4). RESULTS: Plasma malonyldialdehyde, ischaemia-modified albumin and lactate levels increased significantly in group C at t3 and t4 compared with the baseline values. Plasma concentrations of malonyldialdehyde, ischaemia-modified albumin and lactate in groups P and NAC were significantly lower than those in group C at t3 and t4. In blood gas analyses, pH, HCO3 and base excess were found to be significantly lower at t3 and t4 compared with t1 and t2 in group C. Comparisons between groups P and NAC revealed no significant differences. CONCLUSION: Small-dose infusions of both propofol and NAC appear to provide similar protection against ischaemia-reperfusion injury in arthroscopic knee surgery.
