The role of social support on the relationships between internet use and sleep problems in adolescents during COVID-19 pandemic: a multicentre study.

BACKGROUND: This study examines the frequency of problematic internet use and sleep problems in adolescents aged 14-18 years during the COVID-19 pandemic and identifies the impact of factors such as sociodemographic characteristics, internet habits, changes in daily life, and perceived social support on these problems. METHODS: This multicentre study was a questionnaire-based online survey study. The questionnaire included the Young Internet Addiction Scale, the Pittsburgh Sleep Quality Index, and the Multidimensional Scale of Perceived Social Support, as well as questions about demographic information, internet habits, and changes in daily life during pandemic. Several multivariate Backward logistic regression models were run to determine the variables that predicted problematic internet use and poor sleep quality. RESULTS: It was determined that the frequency of problematic internet use was 15.5%, and the frequency of poor sleep quality was 47.8%. Poor sleep quality was found 2.5 times higher in problematic internet users. The perceived social support was found insufficient in adolescents with problematic internet use and poor sleep quality. Various factors such as the excessive use of internet and social media, low school success, lack of physical activity, lack of rules for internet use at home, and worsening of relationships with parents were found to be predictive factors for these problems. CONCLUSIONS: Problematic internet use during the pandemic is associated with worsening sleep quality in adolescents. It is important to create special interventions for problematic internet use and sleep problems that develop in adolescents as a result of restrictions during the pandemic.

Measuring potassium level in packed red blood cells before using: Word of caution for congenital cardiac surgery.

BACKGROUND AND AIM OF THE STUDY: Transfusion-associated hyperpotassemia is a serious complication of packed red blood cell (PRBC) transfusion after congenital cardiac surgery. Our study aimed to identify risk factors and potential preventive measures of transfusion-associated hyperpotassemia in neonates and infants after congenital cardiac surgery. METHODS: Pediatric patients who underwent congenital cardiac surgery and need transfusion were enrolled in this prospective study. The potassium concentration of PRBC was checked from the sample taken from the segment. The volume of transfusion, age of PRBC, potassium concentration of unit were recorded. The estimated increment of potassium level in patients after PRBC transfusion was calculated. RESULTS: Seventy-four individual patients, 95 distinct transfusions, 112 blood products were evaluated. The mean age of the blood unit was 3.8 ± 1.4 days. The mean potassium concentration in the PRBCs was 9.9 ± 2.4 mmol/L. A weak correlation was observed between the potassium value of the PRBC and the age of PRBC (p = 0.049, r = 0.2, y = 0.24 × x + -0.68). There was a weak correlation between the potassium value of PRBCs and the age of the unit (p < 0.001, r = 0.37, y = 2.8 × x + -3.6). CONCLUSIONS: Before transfusion, even PRBC is fresh, measuring the potassium level of PRBC and the potassium that will be given to the pediatric patient with transfusion can prevent transfusion-related hyperpotassemia and related complications. Otherwise, high potassium levels, which may be overlooked despite being fresh, may cause serious complications, even cardiac arrest, especially in neonates and infants.

A retrospective analysis of dexmedetomidine and morphine in the fast-track and ultra-fast-track extubation protocol after congenital cardiac surgery.

BACKGROUND AND AIM OF THE STUDY: After congenital cardiac surgery, the duration of mechanical ventilation (MV) is related to the clinical status, type of operation, and the sedative-analgesic agents used postoperatively. This study aims to examine the effects of dexmedetomidine and morphine on the fast-track extubation (FTE) and ultra-fast-track extubation (UFTE) protocol after congenital cardiac surgery. METHODS: A total of 251 pediatric patients were divided into two groups: 118 patients in the morphine group (Group M) and 133 patients in the dexmedetomidine group (Group D). We retrospectively reviewed medical data including hemodynamic parameters, duration of MV and cardiovascular intensive care unit (CICU), additional sedative/analgesic requirement, adverse events, the need for reintubation, and noninvasive MV, sedation, and pain scores. RESULTS: The mean mechanical ventilation duration of Group D was significantly shorter than Group M (3.74 ± 0.83 h in Group D, 5.72 ± 1.54 h in Group M, respectively) (p = .001; p < .05). In Group D, the success rate of FTE was 92.5% (n = 123) and UFTE was 7.5% (n = 10) (p = .001). In Group M, the success rate of FTE was 72.9% (n = 86) and UFTE was 0% (n = 0) (p > .05). CONCLUSIONS: Dexmedetomidine and morphine have clinical benefits which encourage their use for FTE protocol. Dexmedetomidine has more benefits compared to morphine. It can be used in UFTE protocol, besides its use in FTE protocol with fewer side effects.

Learning curve of ultrasound measurement of subglottic diameter for endotracheal tube selection in pediatric patients.

BACKGROUND: Endotracheal tube size can be predicted according to ultrasound measurement of subglottic airway diameter. The learning curve for this method is not yet established. The aim was to evaluate the learning curve of anesthesiology residents in ultrasound measurement of subglottic airway diameter for prediction of endotracheal tube size using cumulative sum analysis. METHODS: Sixteen anesthesiology residents measured transverse subglottic airway diameter in children undergoing general anesthesia with cuffed endotracheal intubation. Each resident performed 30 ultrasound examinations. Primary outcome was the successful prediction of endotracheal tube size according to ultrasound measurement. Cumulative sum analysis was performed with acceptable and unacceptable failure rates set as 20 and 40%, respectively. RESULTS: Ten out of 16 residents (62.5%) were deemed successful as they were able to pass lower decision boundary, whereas six residents' CUSUM scores were between the decisions lines deeming them indeterminate. The overall success rate for determining the correct endotracheal tube size was 77.5%. Median number of attempts to cross lower decision boundary was 29 with minimum of 18 and maximum of 29 attempts among successful residents. CONCLUSION: Learning curves constructed with cumulative sum analysis in this study showed that only 62.5% of residents were able to correctly predict cuffed endotracheal tube size with 80% success rate. Considerable variability in achieving competency necessitates objective follow-up of individual improvement.

Outcome of treosulfan-based reduced-toxicity conditioning regimens for HSCT in high-risk patients with primary immune deficiencies.

INTRODUCTION: HSCT is the curative therapeutic option in PIDs. Due to the increase in survival rates, reduced-toxicity conditioning regimens with treosulfan have become another alternative. The purpose of this retrospective study was to analyze the outcome of treosulfan-based conditioning before HSCT for patients with PID. METHOD: A total of 15 patients that received a treosulfan-based conditioning regimen for HSCT were recruited. Type of diagnosis, donor and stem cell source, pretransplant organ damage, infections, engraftment, chimerism, and transplant-related toxicities were analyzed. RESULTS: At a median follow-up time of 32 months, the overall survival was 86.7%. Following HSCT, 14 of 15 patients had engraftment, with 86.7% of the cohort having full-donor chimerism. The most common toxicity was seen on the skin (53.3%). Acute GVHD and chronic GVHD were documented in 53% and 20% of the study population, respectively. Although the cohort consisted of patients with pretransplant liver damage, SOS manifestations were documented in 20%. CONCLUSION: Treosulfan-based conditioning regimens before HSCT are associated with lower toxicity compared to myeloablative regimens, are safe, and have high engraftment rates with full-donor chimerism in patients having PID, regardless of the specified genetic diagnosis and donor type.

A Practical Recommendation for Teaching Neck Anatomy During Neck Dissection in the Operating Room.

Anatomy knowledge is not only essential for surgeons but also has importance for anyone who performs an invasive procedure on a patient, and provides examination and diagnosis of patients and sharing of these findings to the patient and other medical professionals. It is accepted that most surgical procedures could facilitate anatomic perception in surgical internships. There is an educational tendency to explore innovative instructional tools and methods that can help support current education styles. This study investigates the effect of a green laser pointer on students' perceptions and educational effectiveness when neck dissection is performed in the operating room.

The role of ultrasound in appropriate endotracheal tube size selection in pediatric patients.

BACKGROUND: The aim of this prospective study was to investigate the success of ultrasound in pediatric patients in determining the appropriate sized cuffed endotracheal tube and to compare the results with conventional height-based (Broselow) tape and age-based formula tube size. METHODS: One hundred and fifty-two children of 1-10 years of age, who received general anesthesia for adenotonsillectomy were enrolled to the study. In all participants, the transverse diameter of the subglottis was measured with ultrasound during apnea. An endotracheal tube was chosen with the outer diameter matched to the measured subglottic airway diameter. An age-based (Motoyama-Khine) and height-based (Broselow) endotracheal tube size was calculated. If there was resistance to passage of the tube into the trachea or an airway pressure >25 cmH2 0 was required to detect an audible leak, the endotracheal tube was replaced with internal diameter of 0.5 mm smaller. If there was an audible leak at airway pressure <10 cmH2 O, or peak pressure >25 cmH2 0 or a cuff pressure > 25 cmH2 O was required to seal, the tube was changed to the 0.5 mm larger internal diameter. Best-fit tube internal diameter was the resultant tube internal diameter that met the previously stated conditions. The need for endotracheal tube replacement and peak airway pressure were recorded. RESULTS: The internal diameter of ultrasound determined tube was the same as best-fit tube in 88% of children. Endotracheal tube was replaced in 15 patients with a one size larger, and in three patients with one size smaller tube. Using Bland-Altman analysis, a better agreement was observed with ultrasound measurement rather than height-based estimation and age-based formulas. CONCLUSION: Our findings show that subglottic diameter measured by ultrasound appears to be a reliable predictor for the assessment of the subglottic diameter of the airway in estimating appropriate size pediatric endotracheal tube.

Bilateral hypoglossal nerve paralysis following elongated styloid process resection: case report.

We report a case of anesthetic management of a 43-year-old patient with Eagle's syndrome (ES) in whom post-extubation acute airway obstruction occurred due to bilateral hypoglossal nerve paralysis. After an accurate examination, elongated bilateral stylohyoid ligament was observed and surgical resection was planned. After completion of the surgery following extubation, significant dysfunction in swallowing, speech function, and tongue motion was observed. The clinical situation was evaluated as bilateral hypoglossal nerve paralysis related to the procedure. The patient was closely observed over 48 h in the intensive care unit. After 2 days, the patient was discharged to a surgical ward. Following clinical assessment, the patient was discharged from hospital for monthly return. At the 6-month follow-up, there were no further episodes of paresthesia and other symptoms. In conclusion, patients with ES represent a real challenge for physicians from diagnosis to treatment, especially regarding perioperative complications, and close collaboration between surgeons and anesthesiologists is of crucial importance.

The effect of pharyngeal packing on gastric volume in patients undergoing nasal surgery: a randomised, controlled trial.

OBJECTIVE: To explore the effects of pharyngeal packing on antral cross-sectional area, gastric volume and post-operative complications. METHODS: In this prospective, randomised, controlled study, 180 patients were randomly assigned to a control group or a pharyngeal packing group. Gastric antral dimensions were measured with pre- and post-operative ultrasound scanning. Presence and severity of post-operative nausea and vomiting and sore throat were recorded. RESULTS: Post-operative antral cross-sectional area and gastric volume were significantly larger in the pharyngeal packing group compared to the control group. The incidence and severity of post-operative nausea and vomiting were significantly less in the pharyngeal packing group. More frequent and severe sore throat was observed in the control group within the ward. An increased Apfel simplified risk score and post-operative antral cross-sectional area were associated with post-operative nausea and vomiting during the first 2 hours, whereas septorhinoplasty and functional endoscopic sinus surgery, absent pharyngeal packing, and lower American Society of Anesthesiologists' physical status were associated with post-operative nausea and vomiting within the ward. CONCLUSION: Regardless of operation type, pharyngeal packing use resulted in smaller gastric volume, which was associated with reduced post-operative nausea and vomiting frequency and severity, and lower sore throat incidence.

Factors influencing blood loss and postoperative morbidity in children undergoing craniosynostosis surgery: a retrospective study.

BACKGROUND: Craniosynostosis is a condition resulting from the premature fusion of cranial sutures. Corrective surgery is often associated with a large amount of blood loss, with transfusion of red blood cells (RBC) and fresh frozen plasma (FFP). The aims of this study were to determine the variables associated with increased blood loss and postoperative complications. METHODS: A retrospective analysis was performed of 42 pediatric patients who underwent craniosynostosis surgery. We analyzed the following: demographic parameters, duration of surgery, intraoperative blood loss, RBC, FFP and fluid transfusion, urine output, and hemodynamic parameters. In addition, we recorded the postoperative length of stay in the intensive care unit and hospital, postoperative blood loss and early complications. RESULTS: The mean age, weight and surgical duration were 9.2 ± 3.2 months, 9.3 ± 2.0 kg and 255.8 ± 46.7 min, respectively. Intraoperative blood loss was 61.2 ± 15.3 ml/kg and RBC, FFP and fluid transfusion were 27.3 ± 7.1 ml/kg, 16.5 ± 4.7 ml/kg and 21.7 ± 4.6 ml/kg/h, respectively. Greater intraoperative blood loss was associated with longer surgical duration (p = 0.001, correlation coefficient = 0.495, R2 = 0.245) and lower patient weight (p < 0.001, correlation coefficient = -0.557, R2 = 0.311). Longer hospital stay was associated with greater intraoperative blood loss (p < 0.001, correlation coefficient = 0.754, R2 = 0.568) and greater intraoperative RBC transfusion (p < 0.001, correlation coefficient = 0.795, R2 = 0.632). CONCLUSION: Severe blood loss occurred in all children who underwent craniosynostotic corrections. Furthermore, the duration of surgery, patient weight and certain surgical procedures correlated with greater blood loss. Careful hemodynamic monitoring and evaluation of a patient's hematocrit value and volume status together may be helpful in maintaining the balance between insufficient and excessive blood product transfusion.

Airway management during unusual tracheal stenosis: A clinical feasibility trial.

Objectives: Prolonged intubation is a known risk factor of LTS. LTS related to COVID-19 may result in a different phenotype: pronation affects the location of stenosis and COVID-19 pneumonia can decline lung mechanics. Therefore, airway management in these patients may carry unique challenges for both anesthesiologists and surgeons.This prospective observational feasibility trial aims to evaluate the use of a novel thin, cuffed, endotracheal tube (Tritube) in combination with flow-controlled ventilation (FCV) in the management of patients with COVID-19-related LTS undergoing laryngeal surgery. Methods: 20 patients suffering from COVID-19-related LTS, as diagnosed by CT, requiring endolaryngeal surgery, with or without CO2 laser, were included. Ultrathin endotracheal tube Tritube, together with FCV was used for airway management and ventilation. Feasibility, ventilation efficiency, and surgical exposure were evaluated. Results: Median duration of mechanical ventilation during their ICU stay was 17 days, (range, 7-27), and all patients had been pronated. In 18/20 patients, endoscopic diagnosis confirmed the initial CT diagnosis: posterior subglottic stenosis. Surgeons' satisfaction on the view was rated 9 out of 10 (range 7-10), where 0 was the worst view and 10 was the best view. Hemodynamic and respiratory variables were within the normal clinical range during the surgical procedure. One patient that had a SpO2 of 90% before induction of anesthesia, a temporal drop to 89%, caused meeting the predefined requirement of "respiratory complication." Conclusion: This study demonstrates the feasibility of using Tritube with FCV in patients with relatively unusual subglottic posterior location tracheal stenosis, undergoing laryngotracheal surgery. Tritube provides a good surgical field and FCV provides highly adequate ventilation especially in patients with compromised lung mechanics. Level of Evidence: IV, non-comparitive prospective clinical trial with 20 patients.

Integration of functional capacity to medically necessary, time-sensitive scoring system: A prospective observational study.

OBJECTIVES: To evaluate 2 new modifications to medically necessary, time-sensitive (MeNTS) scoring systems integrating functional capacity assessment in estimating intensive care unit (ICU) requirements. METHODS: This prospective observational study included patients undergoing elective surgeries between July 2021 and January 2022. The MeNTS scores and our 2 modified scores: MeNTS-METs (integrated Duke activity status index [DASI] as metabolic equivalents [METs]) and MeNTS-DASI-5Q (integrated modified DASI [M-DASI] as 5 questions) were calculated. The patients' ICU requirements (group ICU+ and group ICU-), DASIs, patient-surgery-anesthesia characteristics, hospital stay lengths, rehospitalizations, postoperative complications, and mortality were recorded. RESULTS: This study analyzed 718 patients. The MeNTS, MeNTS-METs, and MeNTS-DASI-5Q scores were higher in group ICU+ than in group ICU- (p<0.001). Group ICU+ had longer operation durations and hospital stay lengths (p<0.001), lower DASI scores (p<0.001), and greater hospital readmissions, postoperative complications, and mortality (p<0.001). The MeNTS-METs and MeNTS-DASI-5Q scores better predicted ICU requirement with areas under the receiver operating characteristic curve (AUC) of 0.806 and 0.804, than the original MeNTS (AUC=0.782). CONCLUSION: The 5-questionnaire M-DASI is easy to calculate and, when added to a triage score, is as reliable as the original DASI for predicting postoperative ICU requirements.

Premature atherosclerosis in children with ß-thalassemia major.

OBJECTIVES: In this study, we aimed to investigate the relationship between chronic hemolysis and increased body iron burden with development of premature atherosclerosis by carotid intima-media thickness (IMT), ferritin, serum lipid profile, homocysteine, nitrate/nitrite, and chitotriosidase enzyme activity in children with ß-thalassemia major. MATERIALS AND METHODS: A total of 31 children with a diagnosis of ß-thalassemia major between the ages of 4 to 16 years constituted the study group. Control group was consisted of 36 age-matched healthy children. Complete blood count, serum glucose, lipid profile, ferritin, homocysteine, calcium, chitotriosidase, and nitrate/nitrite levels were measured and electrocardiographic and echocardiographic investigation and carotid IMT measurement were performed. RESULTS: In study group serum total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol levels were found to be significantly reduced, and very-low-density lipoprotein cholesterol levels were found to be significantly elevated. Plasma nitrate/nitrite levels were significantly reduced; chitotroisidase enzyme activity was significantly increased and carotid IMT was significantly increased in study group. Nitrate/nitrite was found to be the only variable that was statistically significantly related to carotid IMT. CONCLUSIONS: Subclinical atherosclerosis in children with ß-thalassemia major begins early in life, and these children are at risk for development of premature atherosclerosis.

Postoperative Pain in Adolescent Idiopathic Scoliosis Surgery: A Randomized Controlled Trial.

BACKGROUND: Adolescent idiopathic scoliosis (AIS) is the most common type of scoliosis, and its treatment is essentially surgical for curves above 40 degrees. Posterior spinal instrumentation (PI) is the usual technique, while the vertebral body tethering (VBT) method is tested technique for this study as a new treatment option. OBJECTIVES: To compare postoperative pain outcomes between PI and VBT with mini-thoracotomy surgeries performed in AIS patients. STUDY DESIGN: Prospective, randomized controlled study registered with the Clinical Trials Portal (NCT04822935). SETTING: Department of Anesthesiology. METHODS: We randomly divided 31 adolescents (28 women, 3 men) aged 11 to 18, with a diagnosis of AIS into 2 groups using computer software: the PI and the VBT groups. Postoperative morphine consumption and the Numeric Pain Rating Scale (NRS) scores at the 1st, 4th, 8th, 12th, 24th, and 48th hours and at 4 weeks were recorded. Length of hospital stays, length of intensive care unit (ICU) stays, duration of operation, postoperative patient satisfaction with the Likert scale, and complications such as bleeding and respiratory distress were recorded. Preoperative and follow-up Oswestry Disability Index (ODI) questionnaires were obtained to assess patient outcomes at 4 weeks postoperatively. RESULTS: Postoperative morphine consumption and the NRS scores at the 1st, 4th, 8th, 12th, 24th, and 48th hours were significantly higher in group VBT (P < 0.05). The amount of bleeding was significantly higher in group PI (P = 0.002). The ICU and the hospital length of stays in the VBT group were significantly higher (respectively, P = 0.011; P = 0.032). Discharge NRS scores, ODI scores as well as patients' satisfaction were similar in both groups (P > 0.05). LIMITATIONS: Firstly, this was a single-centered study with a small sample owing to the rarity of AIS surgeries. Moreover, double-blinding was not applied to the patients and doctors because of the surgery incision places. CONCLUSION: From our results, both techniques can be employed for AIS surgery, but a meticulous approach is essential for the prevention of acute pain for VBT.

Comparison of Stroke Volume Variation-based goal-directed Therapy Versus Standard Fluid Therapy in Patients Undergoing Head and Neck Surgery: A Randomized Controlled Study

Background: Perioperative fluid therapy is used to avoid dehydration and hypovolemia. Optimum perioperative fluid administration may improve postoperative outcomes after major surgery, and the optimal strategy remains controversial and uncertain. Aims: The primary outcome was the total amount of intraoperative fluids given between perioperative goal-directed fluid therapy (GDFT) guided by a hemodynamic monitoring system and standard fluid therapy based on "mean arterial pressure-diuresis" data in patients undergoing head and neck surgery. The secondary outcomes were the hemodynamics and laboratory variables, postoperative complications, length of mechanical ventilation, intensive care unit and hospital stay. Study Design: A randomized controlled study. Methods: Sixty patients were scheduled and randomized into two groups of 30 patients each: in the study group, an arterial pressure catheter was inserted and connected to the FloTrac system, whereas in the control group, an arterial pressure catheter was inserted and integrated into the hemodynamic monitoring system with a special transducer. The control group had fluids administered at the discretion of the anesthesiologist according to the mean arterial pressure >65 mmHg and diuresis >0.5 ml/kg/h. In the study group, fluid management was administered to achieve a target value of ≤13% through the stroke volume variation. Results: The total amounts of fluid in the intraoperative period were different between the groups, with the study group receiving significantly more fluids (P = 0.0455). The length of hospital stay was significantly longer in the study group than in the control group (P = 0.012), but prolonged oxygen demand was significantly more frequent in the control group than in the study group (P = 0.017). No difference was found in hemodynamics, lactate kinetics, and vasoactive agent requirements. Conclusion: The standard fluid therapy guided by conventional circulatory parameters appears sufficient for patients with low-tomoderate risk during head and neck surgery.

Magnesium and dexmedetomidine combination reduces sodium nitroprusside requirement in laparoscopic pheochromocytoma.

BACKGROUND: Anesthesia management of pheochromocytoma excision surgery is associated with severe hemodynamic fluctuations. The objective of this study is to compare the number of hypertensive crisis requiring sodium nitroprusside (SNP) administration between the groups treated with magnesium (Mg)-dexmedetomidine (Dex) and conventional group in pheochromocytoma. METHODS: This retrospective cohort study included patients who underwent pheochromocytoma surgery between 2011 and 2020. Patients were examined into two groups: 1-Conventional group (GC) included patients who were operated between 2011 and 2015 under standard anesthesia care and who did not receive perioperative additional medication. 2- Mg-Dex therapy group (GMD) comprised the patients who were operated between 2015 and 2020 and who had received 300 mg Mg per oral daily 1 week before the surgery and Mg-Dex infusion intraoperatively. Blood pressure, heart rate (HR), and SNP requirement were recorded throughout surgery as well as demographics and operative data. Hypertensive crisis was defined as systolic blood pressure (SBP) >180 mmHg, and tachycardia was defined as HR >110 bpm. RESULTS: A total of 78 patients' data were analyzed from 108 patients' documentary. (38 in GC, 40 in GMD) SNP requirement was significantly higher in GC (39.5%) comparing GMD (7.5%) (p=0.001). SBPs during tumor manipulation period were statistically higher in GC than in GMD at 10th, 15th, 20th, 25th, 30th, and 35th min. HR values were significantly higher in GC compared to GMD at 10th and 15th min of tumor manipulation period (p<0.05). CONCLUSION: Combination of Mg-Dex seems to be an alternative therapy for reducing vasodilator requirement in perioperative management of pheochromocytoma.

Paravertebral block versus erector spinae plane block for analgesia in modified radical mastectomy: a randomized, prospective, double-blind study.

BACKGROUND: Pain control after breast surgery is crucial and supported with regional techniques. Paravertebral block (TPVB) is shown to be effective in postoperative pain management. Erector spinae plane block (ESPB) is assumed to have a similar analgesic effect as an easier and safer block. Our aim was to compare TPVB and ESPB for modified radical mastectomy (MRM) in terms of analgesic efficiency and dermatomal spread. METHODS: Patients were randomized into Group E (ESPB) and Group P (TPVB). Total 83 patients completed study 42 in Group E and 41 in Group P. Blocks were performed under ultrasonography with 20 mL 0.375% bupivacaine at T4 prior to surgery. T1-10 dermatomal block was examined via pin-prick sensation on the midaxillary and midclavicular lines. Primary outcome was 24-hour morphine consumption. Dermatomal coverage, postoperative 0th minute, 30th minute, 1st, 4th, 6th, 12th and 24th hours pain scores, rescue analgesia requirement and adverse events were secondary outcomes. RESULTS: Morphine consumption was lower in Group P (19.2±2.9 vs. 21±3.1, P=0.007; mean difference 1.8 mg, 95%CI=0.48-3.1 mg). The number of dermatomes with total loss of sensation was higher in Group P. Pain scores were significantly lower in Group P at all time points. The incidence of complications and adverse events was similar in both groups. CONCLUSIONS: Thoracal paravertebral block reduced morphine consumption compared to ESPB after MRM, albeit a small difference. A through coverage of TPVB may be preferred with experienced operators in MRM due to lower pain scores.

Transcutaneous Bilirubin Levels and Risk of Significant Hyperbilirubinemia in Early-Term and Term Newborns.

OBJECTIVE: To compare the course of the transcutaneous bilirubin (TcB) values of early-term newborns with those of term newborns in the first month of life and to investigate whether early-term newborns have an increased risk of significant hyperbilirubinemia requiring treatment. DESIGN: A prospective, controlled cohort analysis. SETTING: A tertiary level mother-child birth and health care center. PARTICIPANTS: Four hundred early-term (37 0/7 to 38 6/7 weeks) and 320 term (39 0/7 to 41 6/7 weeks) newborns born during a 27-month period. METHODS: A total of six TcB measurements in a longitudinal manner were made in early-term and term newborns: the first two at 6 and 48 hours after birth and the next four on routine examination days (Days 4, 7, 15, and 30). Demographic characteristics, values of daily TcB measurements, number of newborns with significant hyperbilirubinemia, and risk of jaundice requiring treatment were compared between the two groups. RESULTS: All six TcB values were significantly greater in the early-term group than in the term group (p < .001 for each). Early-term newborns had a statistically significant increased risk of jaundice requiring treatment compared to term newborns (risk ratio = 1.91; 95% confidence interval [1.23-2.96]; p = .0046). Results of the repeated-measures analysis of variance and post hoc adjusted multiple comparison analysis showed that TcB levels increased to and peaked at 96 hours after birth and then gradually decreased to baseline (first measurement) levels at 30 days after birth in each group. CONCLUSIONS: Early-term newborns should not be treated as full-term newborns because they have significantly higher TcB levels. These newborns should be closely monitored for pathologic jaundice because they have increased risk for significant hyperbilirubinemia requiring phototherapy.
