Patient-controlled analgesia with lornoxicam vs. dipyrone for acute postoperative pain relief after septorhinoplasty: a prospective, randomized, double-blind, placebo-controlled study.

Background and objective: We compared the efficacy of intravenous lornoxicam vs. dipyrone in patient‐controlled analgesia for postoperative analgesia. Methods: The study included 105 patients who had undergone elective septorhinoplasty after receiving general anaesthesia. Patients were divided into three groups to receive lornoxicam (24 mg day−1), dipyrone (5 g day−1) or placebo. Pain was evaluated using a 0‐100 mm visual analogue scale at 2, 4, 6, 8, 12, 16, 20 and 24 h postoperatively. Pethidine (1 mg kg−1) was administered intramuscularly to patients requiring rescue analgesia. Pethidine requirements were recorded during the first 24 h postoperatively, and treatment‐related adverse effects were noted. Results: Postoperative pain scores were significantly lower with lornoxicam compared with dipyrone at 8 h (P = 0.016). No significant differences regarding pain scores at 2, 4, 6, 12, 16, 20 and 24 h were found. Significantly fewer patients in the lornoxicam group required rescue analgesics (vs. dipyrone, P = 0.046; vs. placebo, P = 0.001); fewer patients in the dipyrone group required rescue analgesics compared with placebo (P = 0.008). Significantly fewer patients in the lornoxicam group had nausea (vs. dipyrone, P = 0.022; vs. placebo, P = 0.006); no significant differences were found between the other two groups. Antiemetic use was significantly lower in the lornoxicam group (vs. dipyrone, P = 0.002; vs. placebo, P = 0.001). Conclusions: Lornoxicam has better tolerability and is a more effective analgesic than dipyrone when administered by patient‐controlled analgesia for postoperative analgesia after septorhinoplasty.

Femoral and sciatic nerve block with 0.25% bupivacaine for surgical management of diabetic foot syndrome: an anesthetic technique for high-risk patients with diabetic nephropathy

A case series of patients with diabetic nephropathy, who underwent lower limb debridement or amputation below the knee during successful combined sciatic and femoral nerve block with bupivacaine 0.25%, is presented. Because impaired nerve conduction in diabetes mellitus results in lower local anesthetic agent requirement, a dose-sparing, minimal effective concentration for surgical anesthesia for peripheral nerve blockade may be more favorable for patients with diabetes and chronic renal disease.

A combination of ketamine and dexmedetomidine sedation with caudal anesthesia during incarcerated inguinal hernia repair in three high-risk infants

indicated because of a suspected intestinal perforation. His general condition was bad, tachypnoic, with an enlarged abdomen. His BW was 3350 g. Laboratory results were normal, but for a low level of thrombocytes. He received one dose of platelets before the operation. We performed balanced anesthesia. For fluid replacement, besides cristaloids with albumin 20%, he received erythrocytes, FFP and HES 130 ⁄ 0.4, 20 mLÆh. The operation lasted 4 h. The patient was stable during the operation. Laboratory values and coagulation status remained unchanged. Hydroxyethyl starch 130 ⁄ 0.4 is a relatively new colloid, approved by the FDA on 27 December 2007. It is a poly (O-2-hydroxyethyl) starch in 0.9% NaCl, with an average molecular weight of 130 000 D and a degree of substitution of 0.4 (HES 130 ⁄ 0.4) and osmolality 308 mOsmol l. When compared with albumin, it is seven times cheaper. Standl et al. (1) reported that there is no difference regarding perioperative stabilization of hemodynamics, coagulation parameters, blood gas analyses and other laboratory values between albumin and HES 130 ⁄ 0.4 in children. Moreover they claimed no significant differences in the amount of red blood cells, fresh frozen plasma or platelet concentrations in the two groups. We report two neonates who underwent major surgeries and received HES 130 ⁄ 0.4 along with albumin. Patients were stable during and after the operation. There were no changes in the coagulation status (platelet count, bleeding time, coagulation time, prothrombin time and partial thromboplastin time), although some larger investigations reported some changes (2). No other adverse events occurred. A question remains on the use of colloids vs crystalloids for fluid resuscitation in cricitally ill patients (3), and also which colloid solution is the best (4), particularly in relation to newborns. This case report shows that using HES 130 ⁄ 0.4 can be useful in newborns who undergo major surgeries, with no significant adverse effects, especially in a situation when one does not have other preferable colloids and blood or blood products at one’s disposal. Further studies are needed in this regard.

A Prospective Randomized Double-Blind Study to Determine the Effect of Thoracic Epidural Neostigmine on Postoperative Ileus After Abdominal Aortic Surgery

BACKGROUND: Postoperative ileus is a major gastrointestinal complication of abdominal aortic surgery leading to increased rates of morbidity and mortality, longer lengths of hospital stay, and higher costs. In this study, we evaluated the effect of epidurally administered neostigmine on postoperative ileus after abdominal aortic surgery. METHODS: We enrolled 45 patients who were scheduled for elective abdominal aortic surgery at our institution. All patients received identical general and epidural anesthesia. Before the induction of general anesthesia, an epidural catheter was placed at the T7–T8 intervertebral space, and 20 mL bupivacaine (0.5%) was injected over 15 min. Patients were randomized into two groups. Patients received a 5 mL bolus of neostigmine (1 &mgr;g/kg) diluted with normal saline (Group 1) or a 5 mL bolus of normal saline (Group 2) via an epidural catheter at the end of surgery and 8 h postoperatively. Times of bowel sounds were recorded postoperatively in the intensive care unit. Times of daily passage of flatus and defecation also were recorded. RESULTS: Times to the first bowel sounds and the first flatus were significantly shorter in Group 1 than they were in Group 2 (11.6 ± 11.2 h vs 22.6 ± 12.8 h and 21.8 ± 15.6 h vs 36.6 ± 19.1 h, respectively, P < 0.05). The times to first defecation were similar in both groups (P > 0.05). Nausea was more frequent in patients in Group 2 than in Group 1 (P < 0.05). The incidence of postoperative complications was similar between the groups (P > 0.05). CONCLUSIONS: Thoracic epidural neostigmine enables faster restoration of bowel sounds and shortens duration of postoperative ileus after abdominal aortic surgery.

Intravenous paracetamol and dipyrone for postoperative analgesia after day-case tonsillectomy in children: a prospective, randomized, double blind, placebo controlled study

UNLABELLED Tonsillectomy is associated with severe postoperative pain for which, several drugs are employed for management. OBJECTIVE In this double-blind, placebo-controlled study we aimed to evaluate the efficacy of intravenous paracetamol and dipyrone when used for post-tonsillectomy analgesia in children. METHOD 120 children aged 3-6 yr, undergoing tonsillectomy with or without adenoidectomy and/or ventilation tube insertion were randomized to receive intraoperative infusions of paracetamol (15 mg/kg), dipyrone (15 mg/kg) or placebo (0.9% NaCl). Evaluation was carried out at 0.25, 0.50, 1, 2, 4, 6h postoperatively. Pethidine 0.25 mg/kg was utilized as rescue analgesic. Cumulative pethidine requirement was the primary outcome. Pain intensity measurement, pain relief, sedation level, nausea and vomiting, postoperative bleeding and any other adverse effects were noted. RESULTS No significant difference was found in pethidine requirement between paracetamol and dipyrone groups. Cumulative pethidine requirement was significantly less in paracetamol and dipyrone groups vs. placebo. No significant difference was observed between groups in postoperative pain intensity scores throughout the study. CONCLUSION Intravenous paracetamol is found to have a similar analgesic efficacy as intravenous dipyrone and they both help to reduce the opioid requirement for postoperative analgesia in pediatric day-case tonsillectomy.

An Alternative Central Venous Route for Cardiac Surgery: Supraclavicular Subclavian Vein Catheterization

OBJECTIVE To evaluate the clinical success rate, safety, and usefulness for intraoperative central venous pressure monitoring, and the intravenous access of the supraclavicular subclavian vein approach when compared with the infraclavicular subclavian vein approach and the internal jugular vein approach for central venous catheterization during open-chest cardiac surgery. DESIGN A prospective, randomized, single-center study. SETTING A university hospital. PARTICIPANTS One hundred ninety-five patients scheduled for open-chest cardiac surgery. INTERVENTIONS The study population consisted of patients for whom central vein catheterization was intended during cardiac surgery. Patients were randomized to 3 groups according to the route of central vein catheterization: the supraclavicular group: the supraclavicular approach for the subclavian vein (n = 65); the infraclavicular group: the infraclavicular approach for the subclavian vein (n = 65); and the jugular group: the internal jugular vein approach (n = 65). After the induction of anesthesia, central venous catheterization was performed according to the assigned approach. MEASUREMENTS AND MAIN RESULTS The success rates for the assigned approach were 98%, 98%, and 92% for the supraclavicular, infraclavicular, and jugular groups, respectively (p > 0.05). The success rates in the first 3 attempts in patients who were catheterized successfully according to the assigned approach were 96%, 100%, and 96% for the supraclavicular, infraclavicular, and jugular groups, respectively (p > 0.05). There was no difference among groups in catheter insertion time (p > 0.05). After sternal retraction, central venous pressure trace loss and difficulty in fluid infusion were significantly more frequent in the infraclavicular group (21%) when compared with the supraclavicular (3%) and jugular groups (0%) (p = 0.01). There was no difference among groups in terms of catheter malposition, complications during catheterization, and rate of catheter-related infection. CONCLUSION The supraclavicular approach for subclavian vein catheterization is an acceptable alternative for central venous access during cardiac surgery in terms of procedural success rate, ease of placement, rate of complications, and usability after sternal retractor expansion.

On-pump/beating-heart myocardial protection for isolated or combined coronary artery bypass grafting in patients with severe left ventricle dysfunction : assessment of myocardial function and clinical outcome

BACKGROUND Myocardial protection in coronary artery bypass grafting (CABG) with severe left ventricular (LV) dysfunction is still a surgical dilemma. Preoperative myocardial infarction (MI) and postoperative low output syndrome are serious complications in cases of inadequate protection of the heart, which has limited myocardial reserve. The aim of this study was to evaluate myocardial function and clinical outcome after on-pump/beating-heart CABG in patients with severe LV dysfunction. METHODS Between March 2001 and March 2004, clinical, operative, and postoperative data were prospectively collected from patients with LV ejection fraction (EF) < 30% who underwent on-pump/beating-heart CABG and associated procedures. RESULTS There were 46 patients and the mean patient age was 58.38 +/- 9.23. The mean EF was 25.6 +/- 2.8%. Operating time was 275 +/- 63 minutes. The frequency of distal anastomosis was 3.06 +/- 1.04. Twenty-four patients required aneurysmectomy in addition to CABG, and 2 of the 24 required mitral repairs. Inotropic support was required in 14 patients (30%) and 5 of them (10.9%) also required IABP. The LV EF improved significantly after the operation when compared to preoperative measurements (25.6 +/- 2.8 versus 33.64 +/- 4.69, P < .05). Hospital mortality rate was 4.3% (2 of the 46 patients). No mortality was observed at a mean followup of 16 months after discharge from the hospital. CONCLUSIONS On-pump/beating-heart CABG technique is effective in protecting myocardial functions in patients with severe LV dysfunction. The main advantage of the on-pump/beating-heart technique is the ability it provides one to perform complete revascularization, and intracavitary procedures with low morbidity and mortality even in impaired LV function.

Comparison of Intrathecal Levobupivacaine Combined with Sufentanil, Fentanyl, or Placebo for Elective Caesarean Section: A Prospective, Randomized, Double-Blind, Controlled Study ☆

Background The addition of opioids to local anesthetics contributes to the quality of spinal anesthesia and postoperative analgesia. Objective In our prospective, randomized, double-blind, controlled study, our aim was to compare the effect of low-dose sufentanil plus levobupivacaine or a fentanyl plus levobupivacaine mixture on anesthesia quality, block characteristics, newborn and mother well-being, surgeon satisfaction, and duration of postoperative analgesia. Methods Ninety-three patients were randomized into 3 groups (n = 31). Patients in Group C received 0.5% levobupivacaine (2.2 ± 0.2 mL), Group S received 2.5 µg sufentanil plus 0.5% levobupivacaine (2.2 ± 0.2 mL), and Group F received 10 µg fentanyl plus 0.5% levobupivacaine (2.2 ± 0.2 mL) intrathecally completed to a volume of 3 mL with the addition of saline in all groups. Patients’ demographics, sensory and motor block characteristics, hemodynamics, Apgar scores, umbilical blood gas values, maternal side effects, surgeon satisfaction score, time to first analgesia requirement, and additional analgesic use within 24 hours were recorded. Results In Group S and Group F, target levels of sensory and motor block were achieved more rapidly (P < 0.001). The hemodynamic values were lower (P < 0.05), and the duration of sensory blockade and the time of first analgesic requirement were longer (P < 0.001) in Group S. Additional analgesic requirement during first 24-hour period was lowest in Group S, and highest in Group C (P < 0.001). Apgar scores and umbilical blood gas samples were similar between groups. Postoperative pruritus was more frequent in Group S (P < 0.001) and surgeon satisfaction score was significantly lower in Group C (P = 0.003). Conclusions We suggest that the addition of sufentanil and fentanyl to intrathecal levobupivacaine during caesarean section surgery is more effective than the administration of levobupivacaine alone. The addition of sufentanil to levobupivacaine allowed rapid onset time for sensory and motor block levels. It also extended the duration of postoperative analgesia and led to a decrease in total analgesic requirement. ClinicalTrials.gov identifier: NCT01858090.

Our experiences with spinal anesthesia in pediatric patients

OBJECTIVES The aim of this study was to evaluate the characteristics of spinal anesthesia, including its efficacy, adverse effects and complications, in order to determine if it can be applied safely in pediatric patients at high-risk for general anesthesia. We emphasize our positive outcomes in children undergoing lower abdominal surgery in our previous experience. METHODS The perioperative data of 86 pediatric patients who received spinal anesthesia between 2007 and 2008 were scanned retrospectively. Demographic data, operation types, anesthetic applications, duration of surgery, motor blockade degree, two dermatomes regression time, postoperative analgesic requirements, adverse effects, and complications were recorded. RESULTS The operation time and two dermatomes regression times were found as 49.8 ± 24.1 minutes and 73.0 ± 21.9 minutes, respectively. At the end of the operation, motor blockade had disappeared in 17 patients and persisted in 68 patients. Block time was measured as 67.3 ± 16.2 minutes in these patients. During the intraoperative period, hypotension was observed in two patients, and bradycardia occurred in one patient. Except for these, hemodynamic parameters did not change more than 20% from control values at any time. In three children, surgery was continued under general anesthesia. Forty-six patients required additional analgesic doses in the postoperative period. The time to first analgesic requirement was 2.3 ± 1.2 hours. During the postoperative period, no hemodynamic or respiratory complications were observed. CONCLUSION Spinal anesthesia continues to gain acceptance as an alternative to general anesthesia in children. However, we conclude that accumulated experience is required in order to apply this technique safely in pediatric patients. We emphasize the positive outcomes, adverse events and complications observed in our experience.
