RESUMEN
BACKGROUND: Serratus anterior plane block (SAPB) was evaluated that in patients with the complaint of rib fracture pain in terms of total analgesic consumption and pain scores. METHOD: Sixty patients with rib fracture and NRS (Numeric Rating Scala) pain scores equal or greater than four were included in randomized controlled study. Patients were randomized to perform SAPB or control group. Primary outcome was total tramadol consumption in 24 h. Secondary outcomes were NRS scores (after Patient Controlled Analgesia (PCA) application 30 min, first, second, 4 th, 6 th, 12 th, 24 th hour), peripheral oxygen saturation (first and 24 th hour after PCA application), chronic pain. and complications. RESULTS: The total tramadol consumption significantly lower in group S (p = 0.02). NRS scores after 30 min, 1 h, 2 h, 4 h, 6 h, 12 h, and 24 h were significantly lower in group S than in group C (p < 0.001, p < 0.001, p < 0.001, p < 0.001, p = 0.002, p = 0.026). The total number of patients who reported of chronic pain at rest and during effort was significantly lower in group SAPB than in group C (p = 0.006). Nine patients in group C were reported of pain, four of whom had pain at rest and five had pain during effort. One patient in group S was reported of pain during effort. CONCLUSION: This study demonstrated that SAPB, as part of multimodal analgesia in pain management due to rib fractures, is safe and effective in reducing acute pain.

In low-flow anesthesia (LFA), there is a wash-in period in which usually high fresh gas flow (FGF) rates are used to achieve the required initial concentration of anesthetic agent in the alveoli. The aim of this study was to compare the efficiency, safety and the consumption of desflurane in LFA using constant FGF (1 L/min) and conventional LFA using high FGF (4 L/min) during the wash-in period. Eighty patients, who were scheduled for elective surgery under general anesthesia with endotracheal intubation, were enrolled in the study. Wash-in was accomplished with 1 L/min FGF (50% O2, 50% air) and 18% desflurane in group 1; and by 4 L/min FGF (50% O2, 50% air) and 6% desflurane in group 2. Throughout the surgery, the vaporizer was adjusted to maintain 0.6 to 0.8 minimum alveolar concentration (MAC). The time required to reach 0.7 MAC was shorter in group 1 (160 seconds [135-181] vs 288 seconds [240-500], P < .001). In 6 patients in group 1 and 13 in group 2, vaporizer settings were adjusted to maintain 0.6 to 0.8 MAC (P = .048). Desflurane consumption in the first hour and total desflurane consumption were higher in group 2 (P < .001 and P = .012, respectively). The efficiency of anesthesia in both the first hour and in total was higher in group 1 (P < .001). It is safe, more efficient, and economical to use 1 L/min FGF during the wash-in period in LFA.

Intraoperative neuromonitoring has become an increasingly commonly applied practice during surgical operations for preventing formation of neurological damage. Although it has been used on adults for a long time, the benefits and techniques of applying it in small children are not clear. We applied two different anesthesia protocols during meningomyelocele repair alongside motor-evoked potentials in a newborn and a small infant. We discussed our anesthesia management method and the effects of anesthesia on intraoperative neuromonitoring in our two very young cases in only one of which we obtained significant records.

During the wash-in period in low flow anaesthesia (LFA), high fresh gas flow is used to achieve the desired agent concentration. In this study, we aimed to evaluate the safety of fixed 1 L/min fresh gas flow desflurane anaesthesia in both the wash-in and maintenance periods in patients including the obese ones. 104 patients undergoing surgery under general anaesthesia were included. After endotracheal intubation, fresh gas flow was reduced to 1 L/min and the desflurane vaporizer was set at 18%. The time from opening the vaporizer to end-tidal desflurane concentration reaching 0.7 MAC was recorded (MAC 0.7 time). Throughout the surgery, hemodynamic variables, FIO2, MAC and BIS values were observed. MAC 0.7 time, BIS and MAC values at the start of surgery, number of adjustments in vaporizer settings, desflurane consumption were recorded. The average MAC 0.7 time was 2.9 ± 0.5 min. MAC and BIS values at the start of the surgery were 0.7 (0.6-0.8) and 39 ± 8.5 respectively. No individual patient had a BIS value above 60 throughout the surgery. Hemodynamic variables were stable and FIO2 did not fall below 30% in any patient. The number of adjustments in vaporizer settings was 56. Average desflurane consumption was 0.33 ± 0.05 mL/min. We demonstrated that LFA without use of initial high fresh gas flow during the wash-in period is an effective, safe and economic method which is easy to perform.

Congenital insensitivity to pain with anhidrosis (CIPA) syndrome is a neuropathy characterized by insensitivity to pain, impaired thermoregulation, anhidrosis, and mental retardation. A 9-year old boy with CIPA syndrome, underwent 2 operations for a calcaneal ulcer. During the first operation standard monitorization was performed. In the second operation, Bispectral Index (BIS) monitoring was added and temperature was monitored with an esophageal probe. In the first operation, in which anesthesia induction was applied with ketamine and midazolam, extremity movements with surgical stimuli were seen. Despite pain insensitivity, as extremity movements were seen with surgical stimuli, propofol was administered in the second operation. Throughout the operation, the BIS values varied from 19-58 and body temperature was measured as 36.1°C-36.9°C. In conclusion, despite the absence of pain sensitivity in CIPA syndrome cases, there is an absolute need for the administration of anesthesia in surgical procedures because of tactile hyperesthesia.

BACKGROUND AND OBJECTIVES: Truncal blocks have a place within multimodal analgesia techniques in abdominal surgery. The quadratus lumborum block is a new abdominal truncal block used for somatic analgesia of both the upper and lower abdomen. In this prospective, double-blind, randomized study, we aimed to compare quadratus lumborum block and transversus abdominis plane block in pediatric patients undergoing lower abdominal surgery. METHODS: Fifty-three children undergoing unilateral inguinal hernia repair or orchiopexy surgery were randomized into 2 groups: transversus abdominis plane block and quadratus lumborum block. All blocks were performed under general anesthesia before surgery. Pain levels were assessed using an FLACC (Face, Legs, Activity, Cry, Consolability) scale. RESULTS: The study included 50 patients, after excluding 3 patients who were not eligible. The number of patients who required analgesia in the first 24 hours postoperatively was significantly lower in the quadratus lumborum block group (P < 0.05). In the quadratus lumborum block group, the postoperative 30-minute and 1-, 2-, 4-, 6-, 12-, and 24-hour FLACC scores were lower compared with those of the transversus abdominis plane block group (P < 0.05). Parent satisfaction scores were higher in the quadratus lumborum block group (P < 0.05). CONCLUSIONS: The results of this study showed that in pediatric patients undergoing unilateral inguinal hernia repair or orchiopexy the quadratus lumborum block provided longer and more effective postoperative analgesia compared with the transversus abdominis plane block. CLINICAL TRIALS REGISTRATION: The trial was registered prospectively at clinicaltrials.gov (NCT02715999).

INTRODUCTION: Diabetic patients are susceptible to bacterial, viral and fungal infections because of various deficiencies in the immune system. AIM: To investigate a possible link between hepatitis B/C prevalence and microvascular complications as well as duration of diabetes. MATERIAL AND METHODS: In total 1263 diabetic patients (1149 type 2, 114 type 1) were enrolled in the study. The control group consisted of 1482 healthy blood donors who were over 40 years old. All diabetic patients were tested for HBsAg, anti-HBs and anti-HCV beside routine laboratory tests. Diabetic patients were divided into three groups according to their diabetes duration, and all of the patients were scanned for microvascular complications. Demographic data of all patients were recorded. RESULTS: HBsAg seropositivity was 3.7% in diabetic patients and 1.08% in the control group; this difference was statistically significant (p < 0.001). HBsAg positivity rates in type 1 and type 2 diabetics were 0.8% and 4%, respectively (p = 0.09). HCV seropositivity was 2.2% for diabetics and 0.5% for the control group; this difference was statistically significant (p < 0.001). Anti-HCV seropositivity in type 1 and type 2 diabetics was 1.75% and 2.26%, respectively. There was no relationship between diabetes duration and hepatitis B-C prevalence (p > 0.05). Also, no relationship was found between microvascular complications of diabetes and hepatitis B/C seropositivity. CONCLUSIONS: Hepatitis B and C seroprevalence was found to be increased in diabetes mellitus; however, there was no relationship between hepatitis seroprevalence and the duration or microvascular complications of diabetes.
RESUMEN
PURPOSE: Pulsed magnetic field (PMF) as an important non- invasive alternative therapeutic option has been investigated in several pre-clinical and clinical studies. We also hypothesized that sequenced PMF formed with different frequencies can modulate the diabetes-induced neuropathic signs differently. MATERIALS AND METHODS: Therapeutic actions of sequenced PMF including 1, 5, 1, 5 Hz (low (L)-PMF) or 30, 40, 30, 40 Hz (high (H)-PMF) were examined on improving signs and symptoms of diabetic neuropathic pain in the streptozotocin-induced diabetic rat models by measuring nociceptive parameters such as hyperalgesia and allodynia, and various cytokine levels (tumor necrosis factor [TNF]-alpha, interleukin [IL]-1 beta, IL-6 and IL-10) of spinal cord and sciatic nerve tissues. RESULTS: Ameliorating potential of L-PMF application on signs of diabetes is significantly higher than those of H-PMF. L-PMF partially attenuated the diabetes-induced increase in the blood glucose level, enhanced the decreased thresholds and latency during the experiments. Diabetes enhanced the pro-inflammatory cytokine, TNF-alpha, IL-1 beta and IL-6, levels in spinal cord and sciatic nerve of rats. L-PMF treatments to diabetic rats decreased these, but enhanced the production of anti-inflammatory cytokine, IL-10. CONCLUSIONS: The present results demonstrated that sequenced L-PMF treatment can relieve neuropathic signs of diabetes in rats. Anti-hyperglycemic, anti-allodynic and anti-hyperalgesic effects of L-PMF treatment can be closely correlated with each other. Furthermore, decreasing actions of L-PMF on pro-inflammatory/anti-inflammatory cytokine ratio can suggest that the therapeutic potential of L-PMF in diabetes induced neuropathy may involve the regulation of the neuroinflammatory/neuroimmune processes.

Systemic blood pressure is regulated by three mechanisms: the sympathetic nervous system, the renin-angiotensin system, and the arginine-vasopressin system. Hypotension is a condition that can occur at any stage of management of general anaesthesia, including induction, extubation, and maintenance. Many of the medications used for anaesthesia produce a mild to moderate decrease in systemic vascular resistance (SVR) with a subsequent decrease in arterial blood pressure. Profound and sustained hypotension, however, can have a global impact, resulting in a failure to adequately perfuse systemic capillary networks. The following report describes the case of a 69-year-old man undergoing surgery for total hip replacement who had hypotension that was refractory to fluid administration and inotropic agents at the end of the surgery. In this case study, the role of methylprednisolone therapy in catecholamine-resistant hypotension is also discussed.
RESUMEN
BACKGROUND AND OBJECTIVE: The pneumoperitoneum has been shown to decrease femoral blood flow, resulting in venous stasis. We analyzed the effects of the pneumoperitoneum and epidural analgesia on femoral vein diameter and the peak flow rate of femoral vein during laparoscopic cholecystectomy. PATIENTS AND METHODS: Forty patients were randomly allocated to receive either combined epidural analgesia (EA) and general anesthesia (GA) (group EA/GA) or GA alone (group GA). Laparoscopic cholecystectomy was the standard operation for the selected patients. Then, 10 mL of 1% lidocaine in group EA/GA or physiologic serum in group GA was injected via epidural catheter. Peak flow rates (PFRs) of femoral vein cross-sectional areas (CSAs) were measured from the right femoral vein at three different times: after induction of anesthesia, during the pneumoperitoneum, and after abdominal deflation, but prior to reversal of anesthesia. RESULTS: The two groups were similar in age, sex, body mass index, and duration of operation. The CSA slightly increased after the induction of anesthesia, compared with the previous measurements, although there was no statistical significance between them for both groups (P > 0.05). The PFR decreased, whereas the CSA increased during the pneumoperitoneum in each group. The PFR values after basal measurements were significantly higher in the EA/GA than in the GA group (P < 0.05). Group EA/GA had significantly lower heart-rate and blood-pressure levels during surgery than those in group GA (P < 0.05). CONCLUSIONS: Abdominal insufflation during laparoscopic cholecystectomy results in dilation and decreased flow in the common femoral vein. Epidural analgesia added to the GA partially compensated for the reduction in femoral PFR.

To augment the effects of classical antidepressant drugs by combination therapies in drug-resistant patients has been an emerging treatment strategy. In the present study, the potential synergistic effect of [1H-[1,2,4]Oxadiazole[4,3-a]quinoxalin-1-one] (ODQ) and antidepressant drugs in the forced swimming test was evaluated. While 5mg/kg intraperitoneal administration of imipramine, fluoxetine or desipramine caused no effect in the duration of immobility in the forced swimming test (sub-effective doses), higher doses (20, 10 and 10mg/kg, respectively) reduced the immobility period (effective doses). When sub-effective doses of ODQ (15mg/kg) and imipramine (5mg/kg) were applied, there was a significant reduction in the immobility time compared with those of each drug alone. Similarly the reduction seen with the effective dose of imipramine (20mg/kg) was also augmented by the co-administration of ODQ (15mg/kg). By its sub-effective dose, ODQ exerted statistically significant augmentations in the responses to either sub-effective (5mg/kg) or effective dose (10mg/kg) of fluoxetine. By contrast, desipramine was not influenced by the co-administration of ODQ (15mg/kg). None of the drugs used in the present study had any effects on the locomotor activity test over the dose range applied. The results show that co-administration of imipramine/fluoxetine and ODQ exhibits a supra-additive effect and that serotonergic rather than noradrenergic pathway may be involved in the synergistic effect of ODQ.
