Bacterial and fungal secondary infections occurring in COVID-19 patients followed in intensive care: a retrospective study.

INTRODUCTION: We aimed to investigate the effects of secondary bacterial and fungal infections on patient outcomes in patients followed up in the intensive care unit (ICU) due to coronavirus disease 2019 (COVID-19). METHODOLOGY: We retrospectively analyzed reverse transcriptase polymerase chain reaction (RT-PCR) positive COVID-19 patients followed in the ICU of our hospital between March 2020 and June 2021, using the hospital information system. Demographic data, pathogens causing a secondary infection, onset time of secondary infection, and patient outcomes were recorded. RESULTS: A total of 251 RT-PCR positive patients who met the inclusion criteria were evaluated. The mean length of stay (LOS) in the ICU was 13.3 ± 9.6 days. During this period, 165 (65.7%) patients died. When blood, urine, respiratory tract, and catheter cultures were examined, the number of patients with growth in at least one culture was 129 (51.4%). There was growth in a total of 227 cultures. The highest culture positivity rate was observed in respiratory tract samples (n = 94, 41.4%). Gram-negative bacterial pathogens (n = 130, 58.4%) predominated. Candida spp. was more frequent in urine cultures. The median day of the occurrence of secondary infection was 10 (range: 6-15). Patients who developed secondary infection had a longer LOS and higher mortality rate than patients who did not (p < 0.001). CONCLUSIONS: Gram-negative secondary infections, predominantly in respiratory tract cultures, occurred in COVID-19 patients followed in the ICU. As a result, the LOS was prolonged and mortality rates increased.

Comparison of the Effects of Anaesthesia Methods Used in Caesarean Delivery on Neonatal Cerebral and Renal Oxygenation: A Randomised Controlled Trial.

Background: During a newborn's adaptation to extrauterine life, many changes take place that are influenced by various factors. The type of delivery and anaesthesia strategy utilised during labour can modify these adaptive modifications. In this regard, this study was designed to compare the effects of general and spinal anaesthesia on cerebral and renal oxygenation after elective caesarean deliveries. Methods: This randomised controlled study comprised sixty parturient women who were over 18 years old and had a gestational age between 37 and 41 weeks. All participants had an ASA (American Society of Anesthesiologists) classification of II. Neonatal cerebral (CrSO2) and renal (RrSO2) regional oxygen saturations were assessed using near-infrared spectroscopy. Additionally, the 1st-5th min Apgar scores, preductal and postductal peripheral oxygen saturation (SpO2), and perfusion index were recorded in both the general anaesthesia and spinal anaesthesia groups. Results: There was no statistically significant difference between the two groups in terms of CrSO2 or RrSO2 values. The values of CrSO2 and RrSO2 in both groups showed a significant rise from the 10th to the 15th min, respectively. Conclusions: General and spinal anaesthesia techniques used for cesarean delivery have similar effects on neonatal cerebral and renal oxygenation.

The use of ultrasound guided combined peripheral nerve blocks in a high-risk patient: A case report.

Combined peripheral nerve blocks can be used as an alternative anesthetic technique for lower limb amputations in high-risk patients. The approach may vary according to the clinical condition of the patient. Presently described is the use of a combination of peripheral nerve blocks used for above-the-knee amputation in a high-risk patient: a sciatic nerve block with an anterior approach, a femoral nerve block, and a lateral femoral cutaneous nerve block.

Regional anesthesia in two consecutive surgeries in a patient with mitochondrial neurogastrointestinal encephalomyopathy: a case report.

Mitochondrial Neurogastrointestinal Encephalomyopathy (MNGIE) is a rare autosomal-recessive disorder which is due to mutations in TYMP. The case reported here is of an 18-year-old male with MNGIE syndrome who presented for two different operations on two different occasions under regional anesthesia. The patient presented with urinary incontinence and abdominal pain. A cystoscopy under spinal anesthesia was scheduled. At 3 months after discharge, gastric perforation was diagnosed and combined spinal-epidural anesthesia, surgical repair was planned. Surgical and perioperative periods were uneventful. Based on this experience, we believe that regional anesthesia can be considered safe for use in patients with MNGIE disease.

[S100B level and cognitive dysfunction after robotic-assisted laparoscopic radical prostatectomy procedures: a prospective observational study]. / Nível de S100B e disfunção cognitiva após prostatectomia radical laparoscópica assistida por robô: estudo observacional prospectivo.

BACKGROUND: The present study investigated the association between Postoperative Cognitive Dysfunction (POCD) and increased serum S100B level after Robotic-Assisted Laparoscopic Radical Prostatectomy (RALRP). METHODS: The study included 82 consecutive patients who underwent RALRP. Serum S100B levels were determined preoperatively, after anesthesia induction, and at 30 minutes and 24 hours postoperatively. Cognitive function was assessed using neuropsychological testing preoperatively and at 7 days and 3 months postoperatively. RESULTS: Twenty-four patients (29%) exhibited POCD 7 days after surgery, and 9 (11%) at 3 months after surgery. Serum S100B levels were significantly increased at postoperative 30minutes and 24 hours in patients displaying POCD at postoperative 7 days (p = 0.0001 for both) and 3 months (p = 0.001 for both) compared to patients without POCD. Duration of anesthesia was also significantly longer in patients with POCD at 7 days and 3 months after surgery compared with patients without POCD (p = 0.012, p = 0.001, respectively), as was duration of Trendelenburg (p = 0.025, p = 0.002, respectively). Composite Z score in tests performed on day 7 were significantly correlated with duration of Trendelenburg and duration of anesthesia (p = 0.0001 for both). CONCLUSIONS: S100B increases after RALRP and this increase is associated with POCD development. Duration of Trendelenburg position and anesthesia contribute to the development of POCD. TRIAL REGISTRY NUMBER: Clinicaltrials.gov (N° NCT03018522).

Comparison of ultrasound guided Erector Spinae Plane Block and quadratus lumborum block for postoperative analgesia in laparoscopic cholecystectomy patients; a prospective randomized study.

STUDY OBJECTIVE: Erector Spinae Plane Block (ESPB) is a recently described block. Both ESPB and Quadratus Lumborum block type II (QLB-II) have been reported to provide effective postoperative analgesia in patients undergoing laparoscopic cholecystectomy (LC). In this study, we compared the postoperative analgesic effects of ESPB and QLB-II in patients undergoing LC. DESIGN: Assessor Blinded, prospective, randomized, controlled study. SETTING: Tertiary hospital, postoperative recovery room & ward. PATIENTS: 80 patients (ASA I-II) were recruited. Patients were allocated in to two equal groups (ESB and QLB-II). All patients were included in analysis. INTERVENTIONS: Standard multimodal analgesia was performed in all groups. ESPB and QLB-II were performed under ultrasound guidance. MEASUREMENTS: Mean opioid consumptions and Numeric Rating Scores was measured during the first 24 postoperative hours. MAIN RESULTS: Demographic data was similar between groups. There was no difference between NRS scores and opioid consumption at any hour between the groups. CONCLUSION: While ESPB and QLB-II are not significantly different, they improve analgesia quality in patients undergoing LC.

Minimum effective volume of bupivacaine 0. 5% for ultrasound-guided retroclavicular approach to infraclavicular brachial plexus block / Volume mínimo efetivo de bupivacaína a 0, 5% para abordagem retroclavicular guiada por ultrassom no bloqueio do plexo braquial por via infraclavicular

Abstract Background and objectives: The current study aimed to determine the minimum effective volume (MEV) of bupivacaine 0.5% in 50% of patients for an ultrasound-guided retroclavicular approach to infraclavicular brachial plexus block. Methods: A total of 25 adult patients who were scheduled for upper limb surgery received an ultrasound-guided retroclavicular approach to infraclavicular brachial plexus block with bupivacaine 0.5%. The needle insertion point was posterior to the clavicle and the needle was advanced from cephalad to caudal. Block success was defined as a composite score of 14 at 30 min after local anesthetic (LA) injection. The minimum effective volume in 50% of patients was determined using the Dixon-Massey up-and-down staircase method. Minimum effective volume for a successful block in 95% of the patients was also calculated using logistic regression and probit transformation. Results: The minimum effective volume of bupivacaine 0.5% resulting in successful block in 50% of patients (MEV50) according to the up-and-down staircase method was found to be 9.6 mL (95% confidence interval (CI), 5.7-13.4). The calculated minimum effective volume required for a successful block in 95% of patients (MEV95) using the probit transformation and logistic regression analysis was 23.2 mL (95% CI, 18.8-36.7). Conclusions: The MEV50 of bupivacaine 0.5% for US-guided retroclavicular approach to infraclavicular brachial plexus block was 9.6 mL and the calculated MEV95 was 23.2 mL. Future studies are required for infraclavicular brachial plexus block with different approaches, other LA agents and different concentrations of bupivacaine.

Resumo Justificativa e objetivos: Determinar o volume mínimo efetivo (VE) de bupivacaína a 0,5% em 50% dos pacientes para uma abordagem retroclavicular guiada por ultrassom no bloqueio do plexo braquial por via infraclavicular. Métodos: Um total de 25 pacientes adultos agendados para cirurgia do membro superior receberam abordagem retroclavicular guiada por ultrassom para o bloqueio do plexo braquial por via infraclavicular com bupivacaína a 0,5%. O ponto de inserção da agulha foi posterior à clavícula e a agulha foi avançada de cefálica para caudal. O sucesso do bloqueio foi definido como um escore composto de 14 aos 30 min após a injeção do anestésico local. O VE em 50% dos pacientes foi determinado com o método de escalonamento progressivo-regressivo de Dixon-Massey. O VE para um bloqueio bem-sucedido em 95% dos pacientes também foi calculado com regressão logística e transformação probit. Resultados: O volume mínimo efetivo (VE50) de bupivacaína a 0,5% que resultou em bloqueio bem-sucedido em 50% dos pacientes, de acordo com o método de escalonamento progressivo-regressivo, foi de 9,6 ml (intervalo de confiança de 95%, IC 5,7-13,4). O cálculo do volume mínimo efetivo necessário para um bloqueio bem-sucedido em 95% dos pacientes (VE95) com a análise de transformação probit e regressão logística foi de 23,2 ml (IC 95%, 18,8-36,7). Conclusões: O VE50 de bupivacaína a 0,5% para abordagem retroclavicular guiada por US para o bloqueio do plexo braquial por via infraclavicular foi de 9,6 ml e o VE95 calculado foi de 23,2 ml. Estudos futuros são necessários para o bloqueio do plexo braquial por via infraclavicular com diferentes abordagens, outros anestésicos locais e diferentes concentrações de bupivacaína.

The effects of music on anxiety and pain in patients during carotid endarterectomy under regional anesthesia: A randomized controlled trial.

OBJECTIVE: Music can be used as an alternative method to decrease anxiety in awake patients during surgical procedures. The aim of this study was to test the hypothesis that listening to music during carotid endarterectomy (CEA) under regional anesthesia decreases the patient's anxiety and pain. DESIGN: A multicenter, prospective, randomized controlled trial. SETTING: Patients undergoing carotid endarterectomy under cervical plexus block. INTERVENTIONS: Patients scheduled for carotid endarterectomy under cervical plexus block were randomized into two groups: Music Group and Control Group. MAIN OUTCOME MEASURES: The primary endpoint of this study was the difference in intraoperative anxiety in patients with or without music during CEA under regional anesthesia, and the secondary endpoints were intraoperative and postoperative pain, use of additional local anesthetics, use of intravenous analgesics, patient and surgeon satisfaction and complications. Anxiety was assessed using State Trait Anxiety Inventory (STAI) and numeric rating scale (NRS). Visual analog scale (VAS) was used for pain assessment. RESULTS: The postoperative STAI scores were similar in both groups (p = 0.839). The NRS scores measured immediately after the end of the surgery were statistically higher in Music Group (p = 0.001). The intraoperative anxiety statistically increased in Music Group, when the scores of the intraoperative responses to the questions of "are you relaxed?" and "are you calm?" were compared. (p = 0.0001 and p = 0.0001, respectively). There were no statistical differences in terms of the amount of intraoperative and postoperative analgesic used (p = 0.801, p = 0.773, respectively). The intraoperative VAS scores, postoperative VAS scores, patient and surgeon satisfaction scores were similar in both groups (p = 0.586, p = 0.185, p = 0.302 and p = 0.599, respectively). Systolic, diastolic and mean arterial blood pressure and heart rate were no different between Music Group and Control Group at any of all time points during the intraoperative period. Surgical side and contralateral side cerebral rSO2 values are similar in both groups (p = 0.438, p = 0.397, respectively). CONCLUSIONS: Music use in CEA under regional anesthesia increased intraoperative patient anxiety, and had no effect on intraoperative and postoperative pain or patient satisfaction.

Determination of residual mass in left ventricle by intraoperative transesophageal echocardiography after a giant and floating left atrial myxoma resection / Determinação da massa residual em ventrículo esquerdo por ecocardiografia transesofágica intraoperatória após ressecção de mixoma gigante e flutuante em átrio esquerdo

Abstract Atrial myxoma is a benign tumor of the heart that occurs primarily in the left atrium. Floating or large left atrial myxomas frequently cause functional mitral stenosis, may also affect mitral valve structure and flow, and lead to mitral regurgitation. Systemic embolization occurs in around 30% of cases either from tumor fragmentation or complete tumor detachment hence it should be removed as soon as it is detected. Intraoperative transesophageal echocardiography has a vital importance in the surgery. After resection of myxoma, intraoperative transesophageal echocardiography must be performed to rule out residual mass. The case here reported is of a 48-year old female, who presented with giant and floating left atrial myxoma. Residue mass was detected with intraoperative transesophageal echocardiography in the left ventricle after the resection of myxoma. Subsequently, the residue mass was successfully removed. Complete resection must be required to prevent possible complications such as recurrence, embolization in atrial myxomas. Transesophageal echocardiography performed intraoperatively is vital importance to confirm that the myxoma is completely resected.

Resumo Mixoma atrial é um tumor benigno do coração que ocorre principalmente no átrio esquerdo. Os mixomas flutuantes ou grandes em átrio esquerdo com frequência causam estenose mitral funcional, podendo também afetar a estrutura e o fluxo da válvula mitral e levar à insuficiência mitral. A embolização sistêmica ocorre em cerca de 30% dos casos, quer pela fragmentação do tumor ou pelo desprendimento total do tumor; portanto, o tumor deve ser removido assim que detectado. A ecocardiografia transesofágica intraoperatória tem uma importância vital na cirurgia. Após a ressecção do mixoma, a ecocardiografia transesofágica intraoperatória deve ser feita para excluir a massa residual. O caso aqui relatado é o de uma paciente de 48 anos que apresentou um mixoma de átrio esquerdo gigante e flutuante. A massa residual foi detectada com ecocardiografia transesofágica intraoperatória no ventrículo esquerdo após a ressecção do mixoma. Posteriormente, a massa residual foi removida com sucesso. A ressecção completa é necessária para evitar possíveis complicações, como recorrência e embolização em mixomas atriais. A ecocardiografia transesofágica realizada no intraoperatório é de vital importância para confirmar a ressecção completa do mixoma.

A Randomized Controlled Trial Examining the Effect of the Addition of the Mandibular Block to Cervical Plexus Block for Carotid Endarterectomy.

OBJECTIVES: Although the cervical plexus block generally provides adequate analgesia for carotid endarterectomy, pain caused by metal retractors on the inferior surface of the mandible is not prevented by the cervical block. Different pain relief methods can be performed for patients who experience discomfort in these areas. In this study, the authors evaluated the effect of mandibular block in addition to cervical plexus block on pain scores in carotid endarterectomy. DESIGN: A prospective, randomized, controlled trial. SETTING: Training and research hospital. PARTICIPANTS: Patients who underwent a carotid endarterectomy. INTERVENTIONS: Patients scheduled for carotid endarterectomy under cervical plexus block were randomized into 2 groups: group 1 (those who did not receive a mandibular block) and group 2 (those who received a mandibular block). The main purpose of the study was to evaluate the mandibular block in addition to cervical plexus block in terms of intraoperative pain scores. MEASUREMENTS AND MAIN RESULTS: Intraoperative visual analog scale scores were significantly higher in group 1 (p = 0.001). The amounts of supplemental 1% lidocaine and intraoperative intravenous analgesic used were significantly higher in group 1 (p = 0.001 and p = 0.035, respectively). Patient satisfaction scores were significantly lower in group 1 (p = 0.044). The amount of postoperative analgesic used, time to first analgesic requirement, postoperative visual analog scale scores, and surgeon satisfaction scores were similar in both groups. There was no significant difference between the groups with respect to complications. No major neurologic deficits or perioperative mortality were observed. CONCLUSIONS: Mandibular block in addition to cervical plexus block provides better intraoperative pain control and greater patient satisfaction than cervical plexus block alone.

[Comparison of different methods of nasogastric tube insertion in anesthetized and intubated patients]. / Comparação de diferentes métodos de inserção de sonda nasogástrica em pacientes anestesiados e intubados.

BACKGROUND: Nasogastric tube insertion may be difficult in anesthetized and intubated patients with head in the neutral position. Several techniques are available for the successful insertion of nasogastric tube. The primary aim of this study was to investigate the difference in the first attempt success rate of different techniques for insertion of nasogastric tube. Secondary aim was to investigate the difference of the duration of insertion using the selected technique, complications during insertion such as kinking and mucosal bleeding. MATERIAL AND METHODS: 200 adult patients, who received general anesthesia for elective abdominal surgeries that required nasogastric tube insertion, were randomized into four groups: Conventional group (Group C), head in the lateral position group (Group L), endotracheal tube assisted group (Group ET) and McGrath video laryngoscope group (Group MG). Success rates, duration of insertion and complications were noted. RESULTS: Success rates of nasogastric tube insertion in first attempt and overall were lower in Group C than Group ET and Group MG. Mean duration and total time for successful insertion of NG tube in first attempt were significantly longer in Group ET. Kinking was higher in Group C. Mucosal bleeding was statistically lower in Group MG. CONCLUSION: Use of video laryngoscope and endotracheal tube assistance during NG tube insertion compared with conventional technique increase the success rate and reduce the kinking in anesthetized and intubated adult patients. Use of video laryngoscope during nasogastric tube insertion compared to other techniques reduces the mucosal bleeding in anesthetized and intubated adult patients.

Comparison of the coracoid and retroclavicular approaches for ultrasound-guided infraclavicular brachial plexus block.

PURPOSE: This prospective randomized study compared the coracoid and retroclavicular approaches to ultrasound-guided infraclavicular brachial plexus block (IBPB) in terms of needle tip and shaft visibility and quality of block. We hypothesized that the retroclavicular approach would increase needle tip and shaft visibility and decrease the number of needle passes compared to the coracoid approach. METHODS: A total of 100 adult patients who received IBPB block for upper limb surgery were randomized into two groups: a coracoid approach group (group C) and a retroclavicular approach group (group R). In group C, the needle was inserted 2 cm medial and 2 cm inferior to the coracoid process and directed from ventral to dorsal. In group R, the needle insertion point was posterior to the clavicle and the needle was advanced from cephalad to caudal. All ultrasound images were digitally stored for analysis. The primary aim of the present study was to compare needle tip and shaft visibility between the coracoid approach and retroclavicular approach in patients undergoing upper limb surgery. The secondary aim was to investigate differences between the two groups in the number of needle passes, sensory and motor block success rates, surgical success rate, block performance time, block performance-related pain, patient satisfaction, use of supplemental local anesthetic and analgesic, and complications. RESULTS: Needle tip visibility and needle shaft visibility were significantly better in group R (p = 0.040, p = 0.032, respectively). Block performance time and anesthesia-related time were significantly shorter in group R (p = 0.022, p = 0.038, respectively). Number of needle passes was significantly lower in group R (p = 0.044). Paresthesia during block performance was significantly higher in group C (p = 0.045). There were no statistically significant differences between the two groups in terms of sensory or motor block success, surgical success, block-related pain, and patient satisfaction. CONCLUSION: The retroclavicular approach is associated with better needle tip and shaft visibility, reduced performance time and anesthesia-related time, less paresthesia during block performance, and fewer needle passes than the coracoid approach.

Use of McGrath MAC Videolaryngoscope to Assist Transesophageal Echocardiography Probe Insertion in Intubated Patients.

OBJECTIVES: Transesophageal echocardiography (TEE) probe insertion with the conventional blind insertion technique may be difficult in anesthetized and intubated patients. The use of a videolaryngoscope may facilitate the insertion of the TEE probe. The aim of this study was to compare the conventional technique with the use of the McGrath MAC videolaryngoscope for TEE probe insertion in terms of success rate, duration of insertion, and complications in patients undergoing cardiovascular surgery. DESIGN: A prospective, randomized study. SETTING: Training and research hospital. PARTICIPANTS: Eighty-six adult patients undergoing cardiovascular surgery were included. INTERVENTIONS: Eighty-six adult patients were randomized into 2 groups: conventional group (n = 43) and McGrath videolaryngoscope group (n = 43). Success rates, duration of insertion, complications, and hemodynamic changes during insertion were recorded. MEASUREMENTS AND MAIN RESULTS: The success rate of TEE probe insertion at the first attempt was higher in the McGrath videolaryngoscope group (90.5%) than in the conventional group (43.9%) (p = 0.012). The mean duration for successful insertion of the TEE probe at the first attempt was longer in the McGrath videolaryngoscope group (24 s v 11 s) (p = 0.016). The total time for successful insertion of the TEE probe was similar in both groups. Pharyngeal injuries were observed more frequently in the conventional group (17.1% v 2.4%) (p = 0.037). The rate of blood presence on the probe tip in the conventional group was higher than in the McGrath group (21.9% v 4.8%). There were no statistical differences between the 2 groups in systolic blood pressure, mean arterial pressure, diastolic blood pressure, and heart rate before and after TEE insertion. CONCLUSIONS: The use of the McGrath MAC videolaryngoscope for TEE insertion in cardiovascular surgery patients increases the success rate and reduces pharyngeal injuries compared to the conventional technique. The use of the McGrath MAC videolaryngoscope for TEE insertion causes similar hemodynamic changes as in the conventional blind insertion technique.

Mitral valve repair facilitated with transapical beating heart NeoChord implantation in a non-Hodgkin's lymphoma patient.

Elderly patients with severe hematological malignancies may require cardiac surgery. The combined impact of cardiopulmonary bypass (CPB) and surgical trauma is a potent inflammatory activator and is increased by intraoperative and postoperative complications. To avoid the adverse effects of CPB, minimally invasive off-pump techniques may be used in these patients. The transapical off-pump mitral valve intervention with NeoChord implantation (TOP-MINI) is a minimally invasive technique for mitral valve repair, which makes it possible to avoid the risks of CPB in selected patients, such as elderly, cancer or immunosuppressive patients. We report here the case of a 78-year-old male with B-cell non-Hodgkin's lymphoma, who presented with severe mitral regurgitation. The patient was successfully treated with the TOP-MINI procedure.

Comparison of Combined (Deep and Superficial) and Intermediate Cervical Plexus Block by Use of Ultrasound Guidance for Carotid Endarterectomy.

OBJECTIVES: Carotid endarterectomy under regional anesthesia may be performed by using superficial, intermediate, deep or combined cervical plexus block. The authors compared the combined and intermediate cervical plexus block by use of ultrasound guidance in patients undergoing carotid endarterectomy. DESIGN: A prospective, randomized, double-blinded trial. SETTING: Education and research hospital. PARTICIPANTS: Adult patients undergoing carotid artery surgery. INTERVENTIONS: Forty-eight patients were randomized to receive either combined cervical plexus block (deep plus superficial) or intermediate cervical plexus block by use of ultrasound guidance for carotid endarterectomy. The primary outcome measure was the amount of supplemental 1% lidocaine used by the surgeon. Secondary outcome measures were the time for the first analgesic requirement after surgery, block-related complications, postoperative visual analog scale score, and patient and surgeon satisfaction. MEASUREMENTS AND MAIN RESULTS: Intraoperative supplemental lidocaine requirements were 3.0±1.9 mL in the combined-block group and 7.8±3.8 mL in the intermediate block group. These differences were statistically significant. There were no significant differences between the 2 groups in block-related complications and the time between the block completion and the first administration of the first dose of intravenous analgesic. In the combined-block group, maximum visual analog scale score was lower at 3 hours (2.2 [1-5] v 5.3 [3-8]), and patient satisfaction score was higher than the intermediate-block group (4.3 [3-5] v 3.1 [1-4]). One regional anesthesia procedure was converted to general anesthesia in the combined-block group. CONCLUSIONS: Ultrasound-guided combined cervical plexus block compared to intermediate cervical plexus block led to less additional analgesic use, lower visual analog scale score, and higher patient satisfaction.

Effects of Parasternal Block on Acute and Chronic Pain in Patients Undergoing Coronary Artery Surgery.

Background Sternotomy causes considerable postoperative pain and postoperative pain management encompasses different analgesic regimens. In this study, we aimed to investigate the effect of peroperative parasternal block with levobupivacaine on acute and chronic pain after coronary artery bypass graft surgery. Materials and Methods A total of 81 patients undergoing coronary artery bypass graft surgery were included in this study. Patients were randomly allocated by opening an envelope to receive either parasternal block with pharmacologic analgesia (group P; before sternal wire placement: sternotomy and mediastinal tube sites were infiltrated with local anesthetics) or pharmacologic analgesia alone (group C) for postoperative pain relief. All patients received intravenous tramadol with patient-controlled analgesia at the end of the surgery. Demographic characteristics, vital signs, tramadol consumption, analgesic intake, and intensity of pain with a visual analogue scale were recorded for each patient. Six months after surgery, the patients' type of chronic pain was evaluated using the Leeds Assessment Neuropathic Symptoms and Signs pain scale questionnaire. Results Patients who received parasternal block experienced less pain and needed less opioid analgesic (125.75 ± 28.9 mg in group P vs 213.17 ± 61.25 mg in group C) for 24 hours postoperatively (P < .001). There was no significant difference in nociceptive and neuropathic pain between the groups. Conclusion Parasternal block had a benefical effect on the management of postoperative acute pain and decreased opioid consumption after surgery but had no significant effect in chronic post surgical pain.
