RESUMEN
Background: Postoperative pain management is an important aspect of anesthesia care and multimodal analgesic techniques are generally recommended. Objective: To compare the effect of spinal anesthesia + transversus abdominis plane (TAP) block application on postoperative analgesia quality and patient satisfaction with spinal anesthesia + intrathecal morphine (ITM) application. Methods: A total of 70 patients were randomly separated into 2 groups as spinal anesthesia + TAP block (TAP block group, n = 34) and spinal anesthesia + ITM group (ITM group, n = 36). The groups were compared in respect of age, body mass index values, and visual analog scale (VAS) values at 0 h, 2 h, 6 h, 12 h, and 18 h, and patient satisfaction was scored by Quality Improvement in Postoperative Pain Management at 24 h. Results: The mean age of the patients was 32.52 ± 6.50 years in the TAP block group and 30.11 ± 5.62 years in the ITM group, with no statistically significant difference determined. There was no statistically significant difference in terms of VAS values at 0 h, 2 h, 6 h, 12 h, and 18 h. When the factors affecting postoperative patient satisfaction were evaluated, feeling fatigue after the surgery (r = -0.811, P = 0.001) and postoperative complications such as nausea, vomiting, and itching (r = -0.831, P = 0.001) were found to have a negative effect on patient satisfaction. Conclusion: Due to low complication rates, TAP block is an effective application for postoperative analgesia management in varicocele operations that increases patient satisfaction postoperatively.
RESUMEN
PURPOSE: The aim of this study was to determine the usefulness of the lamina cribrosa thickness (LCT) and lamina cribrosa depth (LCD) in adolescence with attention-deficit hyperactivity disorder (ADHD) and compare with those receiving methylphenidate (MPH) and healthy controls. METHODS: Fifty-five children with ADHD (9.23 ± 1.92 years, mean ± standard deviation), 41 children with ADHD given MPH (9.24 ± 1.84 years), and 86 healthy controls (9.95 ± 2.16 years) were recruited for the study. All subjects were subjected to a complete eye exam and optical coherence tomography (OCT) was used to assess LCT and LCD. The severity of ADHD symptoms was evaluated by using parent-report measures, including Conners's Parent Rating Scale-Revised: Short Form (CPRS-R: S) and the Strengths and Difficulties Questionnaire: Parent Form (SDQ: P). RESULTS: The study showed a significant finding between the research groups with regard to LCT. LCT was shown to be significantly increased in ADHD subjects given MPH compared with the controls. However, LCD was not significantly different between cohorts. Also, a significant inverse correlation was found between the SDQ: P-Emotional Problems Subscale and LCT (r = -0.253; P = 0.030) in ADHD patients. CONCLUSION: Changes in lamina cribrosa (LC) in ADHD children receiving MPH suggest that the mechanism of action for MPH may target developing LC structures. More studies to define the relationship between MPH medications and the LC variations are defensible.

OBJECTIVES: This study was a comparison of the thickness of the choroid in pediatric patients with attention-deficit hyperactivity disorder (ADHD) and healthy pediatric controls. METHODS: This study was comparative, cross-sectional, and observational in design. The healthy controls were age- and sex-matched with the members of the ADHD group and had no history of psychosis. Choroidal thickness was determined using spectral-domain optical coherence tomography. RESULTS: A total of 138 patients were enrolled with a male:female ratio of 54 (69.2%): 24 (30.8%) in the ADHD group and 41 (68.3%): 19 (31.7%) in the control group (p=0.910). The ADHD patients had a mean age of 9.4±1.9 years (range: 6-12 years) and the controls had a mean age of 9.9±2.2 years (range: 6-12 years) (p=0.213). The ADHD group (n=78 eyes tested) had a significantly higher mean choroidal thickness at 1.5 mm (temporal-to-fovea, TTF) measurement than the controls (n=60 eyes tested) (281.12±46.63 µm vs. 264.40±48.61 µm, p=0.042). There were no significant differences in any of the other choroidal thickness measurements (p>0.05). CONCLUSION: The choroidal thickness measurement (TTF) at 1.5 mm was significantly greater in the ADHD patients. These findings suggest that choroidal thickness alterations may have a potential role in the underlying etiology of ADHD.
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.

Ultrasound-guided vascular access is a technique that can increase safety as well as technical and procedural success when performing invasive cardiovascular procedures. The aim of this study was to evaluate the effects of two cannulation techniques and vascular morphological properties on the success of femoral artery catheterisation in neonatal patients. We recruited 65 consecutive patients requiring femoral artery catheterisation and randomly divided them into two groups: Group 1, in-plane technique (n = 31) and Group 2, out-of-plane technique (n = 34). We compared the preparation duration, puncture duration, number of punctures, number of arterial punctures, number of unsuccessful interventions, hematoma incidence and vascular morphological characteristics between the groups. The mean age of Group 1 was 17.16 ± 7.04 days, and the mean age of Group 2 was 17.20 ± 7.40 days, with no difference observed between the groups (p > 0.05). Four patients in Group 1 and nine patients in Group 2 developed hematoma (p = 0.172). Hematoma was strongly correlated with the number of venous punctures (r = 0.632; p = 0.001) and the number of needle advancements (r = 0.415; p = 0.001). In terms of artery-vein position, patients whose artery overlapped the vein by > 50% required clearly longer artery cannulation durations than the other patients (p < 0.001). Although the in-plane technique has a steep learning curve, it was found superior in terms of procedure-related factors such as the number of trials, the incidence of hematoma and arterial puncture counts, as it offers advantages such as the ability to evaluate the lumen and a better control of the needle advancement direction.

PURPOSE: To define diurnal changes in anterior segment parameters of keratoconus patients by using Scheimpflug imaging. METHODS: All keratoconus patients had corneal topography measurements 3 times a day (around 09:00 AM, 13:00 PM and 17:00 PM) by the same experienced operator. Three consecutive scans in each measurement session were obtained. The average of three measurements was used for analysis. A repeated measures analysis of variance with one within-subject factor (time of day) was carried out to assess diurnal variation. RESULTS: This study included 26 eyes of 26 patients with keratoconus. Significant diurnal variation was found in CCT and TCT measurements (P < 0.01, and P < 0.01, respectively). The mean amplitudes of change in CCT and TCT were 4.2 ± 1 µm (95% CI: 1.7-6.8 µm) and 4.1 ± 1.1 µm (95% CI: 1.2-8.0 µm), while the mean of CCT and TCT were 462.4 ± 34.5 µm (95% CI: 448.4-476.6 µm) and 452.9 ± 6.6 µm (95% CI: 439.3-466.5 µm), respectively. The maximum value and the lowest value were observed at 09:00 AM and at 17:00 PM, respectively. Other parameters except CCT and TCT did not show diurnal variation. CONCLUSION: Statistically significant but clinically insignificant diurnal variation in CCT and TCT measurements of the keratoconus patients were detected over an 8-hour period (09:00 AM-17:00 PM).

BACKGROUND AND OBJECTIVES: Caudal epidural anesthesia is a widely used popular technique for postoperative analgesia but it has potential side effects and duration of analgesia is short. Quadratus lumborum block (QLB) was found to be an effective method for postoperative analgesia in lower abdominal surgeries. In this double-blind prospective randomized trial, we aimed to compare the postoperative analgesic efficacies of QLB and the caudal block in pediatric patients undergoing inguinal hernia repair and orchiopexy surgeries under general anesthesia. MATERIALS AND METHODS: After approval was obtained from the ethics committee, in this prospective randomized double-blind trial, 53 patients under general anesthesia undergoing inguinal hernia repair and orchiopexy surgeries randomly received caudal block or QLB. Demographic data, postoperative analgesic requirement, Face, Legs, Activity, Cry, and Consolability (FLACC) scores at 30 min, 1, 2, 4, 6, 12 and 24 hours, parent satisfaction scores and complications were recorded. RESULTS: The study included 52 patients, after excluding one patient because of a failed caudal block. There were no significant differences between the groups based on demographic data (p>0.05). The number of patients who required analgesics in the first 24 hours was significantly lower in QLB group (p=0.001). Postoperative 4, 6, 12 hours FLACC scores were significantly lower in the QLB group (p<0.001, p=0.001 and p<0.001, respectively). Parent satisfaction scores were higher in the QLB group (p=0.014). CONCLUSION: According to the results of this study, QLB can provide much more effective analgesia than caudal block without adjuvants in multimodal analgesia management of children undergoing inguinal hernia repair and orchiopexy surgeries. TRIAL REGISTRATION NUMBER: NCT03294291.

The aim of this study was to take ultrasonographic measurements of the length of the ligamentum flavum (LF), the LF-skin distance and the interspinous distance, which are critical for the application of neuraxial anaesthesia, with volunteers in the sitting position and with lateral tilt of the operating table at different angles to evaluate whether the target structures in neuraxial anaesthesia can be better visualised with the lateral tilt position and to determine whether or not these measurements change at different angles. The study included 29 volunteers. For the measurements, the operation table was first set into the neutral position and the length of the LF, the skin-LF distance and the interlaminar distance were measured at between L1-S1 spaces with a paramedian oblique sagittal approach with a linear ultrasound probe. Then the table was moved into 5°, 10° and 15° lateral tilt positions and the LF, LF-skin distance and the interlaminar distance were measured at the L1-S1 interspaces and recorded. At L2-3, L3-4, L4-5 and L5-S1 intervertebral interspaces, as the lateral tilt angle increased, so the measured LF length and interlaminar distance was determined to increase, this increase was statistically significant. In the ultrasonographic measurements of the skin-LF distance, at L3-4 and L4-5 intervertebral interspaces, there was a statistically significant increase. With lateral tilt applied to the table, there was determined to be an increase in ultrasonographic measurements of the LF length in the lumbar intervertebral interspaces. Therefore, for neuraxial blocks applied in the sitting position, the procedure may be facilitated with lateral tilt of the operating table.

The quadratus lumborum block (QLB) is a newly described block providing successful, safe, and long-lasting analgesia with the guidance of ultrasound. The QLB allows local anesthetic to spread posterior to the quadratus lumborum muscle and expand beyond the middle layer of the thoracolumbar fascia and paravertebral space. We present our experience with the use of an unilateral QLB to provide postoperative analgesia in a 3-year-old pediatric patient weighing 14 kg who underwent a unilateral inguinal hernia repair. His family was satisfied with the general status and pain cessation in the patient.

OBJECTIVE: This study aimed to investigate the preoperative level of serum leptin in cesarean section (C-section) patients with and without acute labor pain and its association with postoperative analgesic consumption and preoperative pain threshold. MATERIALS AND METHODS: Preoperative leptin levels, preoperative pain threshold, postoperative analgesic consumption in the first 24 h, and postoperative pain severity (visual analog scale (VAS) scores at 1, 2, 4, 6, 12, and 24 h postoperatively) in C-section patients with labor pain (emergency C-section; n = 21) and without labor pain (elective C-section; n = 25) were compared. RESULTS: There were no signiï¬cant differences between the groups regarding the demographic characteristics. Leptin levels, postoperative VAS scores, and analgesic consumption were significantly higher in the group with labor pain, while the preoperative pain threshold was lower. Serum leptin levels correlated negatively with pain threshold and positively with postoperative analgesic consumption. Multiple linear regression analyses in our study revealed that the preoperative leptin levels and having an emergency C-section independently affected the postoperative analgesic consumption and preoperative pain threshold, whereas their combined effects on these parameters were statistically not significant. CONCLUSION: Preoperative levels of serum leptin were higher in C-section patients with labor pain than in those without labor pain, and increased serum leptin levels were associated with decreased preoperative pain threshold and increased postoperative analgesic consumption in our study population. Postoperative analgesic requirements may vary among patients, and their requirements might be predicted using preoperative indicators. Serum levels of leptin might be one such indicator and this warrants further studies with larger sample sizes.

PURPOSE: The aim of this prospective, randomized, double-blind study was to compare the tumescent anesthesia method and erector spinae block with respect to postoperative analgesia consumption, pain scores and patient satisfaction, in patients receiving breast reduction surgery under general anesthesia. METHODS: The study included 44 females, aged 20-65 years, who were to undergo breast reduction surgery, without adjunctive liposuction on the breast. Using the closed envelope method, the patients were randomly separated into two groups to receive tumescent anesthesia or erector spinae block (ESB). Patients in the ESB group received the block before general anesthesia by a single anesthetist (G.Ö.). RESULTS: The 24-h tramadol consumption with PCA, which was the primary outcome of the study, was determined to be statistically significantly less in the ESB group (p < 0.001). The NRS scores were compared at 30 min postoperatively and then at 1, 2, 4, 6, 12 and 24 h. At all the measured time points, the pain scores of the ESB group were statistically significantly lower (p < 0.001). Additional analgesia was required by one patient in the ESB group and by seven patients in the tumescent group and was applied as 1 g paracetamol. The requirement for additional analgesia was statistically significantly lower in the ESB group (p < 0.024). Patient satisfaction was statistically significantly better in the ESB group (p < 0.001). CONCLUSIONS: According to the results of this study, bilateral ESB performed under ultrasound guidance in breast reduction surgery was more effective than tumescent anesthesia concerning postoperative analgesia consumption and pain scores. ESB could be an appropriate, effective and safe postoperative analgesia method for patients undergoing reduction mammoplasty surgery.

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.

Background/aim: This study was planned by considering that the use of bispectral index (BIS) monitoring ensures sufficient depth of anesthesia and avoids anesthetic awareness and patient movement in the oocyte pick-up (OPU) procedure.Materials and methods: Ninety-eight patients undergoing OPU were randomly divided into 2 groups as the control group (n = 48) and BIS group (n = 50). After propofol and remifentanil induction, the control group was given additional propofol according to reaction response, while the BIS group was given propofol at BIS values of 60 and above with the aim that BIS values be 40?60. Total procedure time, recovery time, patient movement, additional propofol consumption, total number of oocytes, and awareness during anesthesia were recorded. Results: Demographic data were similar in the two groups (P > 0.05 for all). The recovery time in the BIS group was significantly shorter compared to the control group (P < 0.001) while additional propofol consumption was found to be significantly lower (P < 0.001). Baseline BIS values fell compared to all other times after induction significantly (P < 0.001). No patient had anesthesia awareness.Conclusion: During the OPU procedure BIS monitoring is considered to prevent anesthesia awareness, intraoperative movement, and complications caused by insufficient anesthetic use as it ensures optimal doses of anesthetic agents used and early recovery.
RESUMEN
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.

Abstract Background and objectives Ultrasound-guided transversus abdominis plane block demonstrated efficacy in providing post-operative analgesia by prolonging the time to first analgesic requirement and reducing the total analgesic consumption. The surgical transversus abdominis plane block, a novel technique, can be performed safely in obese patients in whom muscle layers cannot be sufficiently exposed. Here, we compared applicability, efficacy and complications of surgical transversus abdominis plane and ultrasound-guided transversus abdominis plane blocks in obese pregnant women following cesarean section under general anesthesia. Methods Seventy-five pregnant women with pre- and post-pregnancy body mass index > 30 were randomized and allocated into two groups: Ultrasound-guided transversus abdominis plane block (UT group; n = 38) and surgical TAP block (ST group; n = 37). Visual analogue scale scores at post-operative 0, 2, 6, 12 and 24 hours (h), time to first analgesic requirement, total analgesic consumption amount in 24 h, post-operative side effects, complications and patient satisfaction were recorded. Results and conclusions Age, American Society of Anesthesiologist score, operative duration, body mass index, mean time to first analgesic requirement and total analgesic consumption in 24 h were similar between groups, while significant differences in pre- and post-pregnancy body mass index were observed between groups. Block procedure durations were 7 and 10 minutes in ST and UT groups, respectively. No significant differences in visual analogue scale scores were observed between the groups at all times; itching and nausea was observed in one (UT group) and four (UT and ST groups) patients, respectively. Surgical transversus abdominis plane block was safe in obese pregnant patients and provided similar post-operative analgesia to ultrasound-guided transversus abdominis plane block.
Resumo Justificativa e objetivos O bloqueio do plano transverso abdominal (TAP) guiado por ultrassom (US) demonstrou eficácia no fornecimento de analgesia no pós-operatório ao prolongar o tempo até a primeira necessidade de analgésico e reduzir o consumo total de analgésico. O bloqueio TAP cirúrgico (uma nova técnica) pode ser realizado com segurança em pacientes obesas nas quais as camadas musculares não podem ser suficientemente expostas. Comparamos a aplicabilidade, a eficácia e as complicações do bloqueio TAP cirúrgico e do bloqueio TAP-US em gestantes obesas submetidas à cesárea sob anestesia geral. Método Setenta e cinco mulheres grávidas com índice de massa corporal (IMC) pré e pós-gravidez > 30 foram randomicamente alocadas em dois grupos: bloqueio TAP-US (Grupo TAP-US, n = 38) e bloqueio TAP cirúrgico (Grupo TAP-C, n = 37). Os escores da escala visual analógica (VAS) nos tempos 0, 2, 6, 12 e 24 horas de pós-operatório, o tempo até a primeira necessidade de analgésico, o consumo total de analgésico em 24 horas, os efeitos colaterais no pós-operatório, as complicações e a satisfação do paciente foram registrados. Resultados e conclusões Idade, estado físico ASA, tempo cirúrgico, IMC, média de tempo até a primeira necessidade de analgésico e consumo total de analgésico em 24 horas foram semelhantes entre os grupos, enquanto diferenças significativas foram observadas entre os grupos em relação ao IMC pré- e pós-gravidez. As durações dos procedimentos de bloqueio foram de 7 e 10 minutos nos grupos TAP-US e TAP-C, respectivamente. Não houve diferença significativa nos escores VAS entre os grupos em todos os momentos; prurido e náusea foram observados em um paciente (Grupo TAP-US) e em quatro (Grupo TAP-C), respectivamente. O bloqueio TAP cirúrgico foi seguro nas pacientes grávidas obesas e forneceu analgesia similar à do bloqueio TAP-US no pós-operatório.

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).
