Abstract PDF: Background
Patients with a fractured femur experience intense pain during positioning for neuraxial block for definitive surgery. Femoral nerve block (FNB) is therefore often given prior to positioning for analgesia. In our study, we compare the onset and quality of block of 0.25% bupivacaine, 0.5% ropivacaine, and 1.5% lignocaine for FNB in fracture femur patients. Methods: Seventy-five adult femur fracture patients were equally and randomly divided into three groups to receive 15 ml of either 0.25% bupivacaine (group B), 0.5% ropivacaine (group R), or 1.5% lignocaine (group L) for FNB prior to positioning for neuraxial blockade. Onset and quality of block were assessed, as well as improvement in visual analog scale (VAS) score, ease of positioning, and patient satisfaction. Results: Percentage decrease in VAS was found to be highest in group R (82.8%) followed by groups L and B. Time to achieve a VAS of less than 4 was found to be 26.2±2.4 minutes in group B, 8.5±1.9 minutes in group R, and 4.1±0.7 minutes in group L (P<0.001). In group B, 12 patients required additional fentanyl to achieve a VAS <4. Patient positioning was reported to be satisfactory in all patients in group R and L, while in B it was satisfactory in 13 (52%) patients only. Patient acceptance of FNB was 100% in group R and L, but only 64% in group B. Conclusions: Based on our findings, 0.5% ropivacaine is a favorable choice for FNB due to early onset, ability to yield a good quality block, and good safety profile.

Background
Optic nerve sheath diameter (ONSD) is an emerging non-invasive, easily accessible, and possibly useful measurement for evaluating changes in intracranial pressure (ICP). The utilization of bedside ultrasonography (USG) to measure ONSD has garnered increased attention due to its portability, real-time capability, and lack of ionizing radiation. The primary aim of the study was to assess whether bedside USG-guided ONSD measurement can reliably predict increased ICP in traumatic brain injury (TBI) patients. Methods: A total of 95 patients admitted to the trauma intensive care unit was included in this cross sectional study. Patient brain computed tomography (CT) scans and Glasgow Coma Scale (GCS) scores were assessed at the time of admission. Bedside USG-guided binocular ONSD was measured and the mean ONSD was noted. Microsoft Excel was used for statistical analysis. Results: Patients with low GCS had higher mean ONSD values (6.4±1.0 mm). A highly significant association was found among the GCS, CT results, and ONSD measurements (P<0.001). Compared to CT scans, the bedside USG ONSD had 86.42% sensitivity and 64.29% specificity for detecting elevated ICP. The positive predictive value of ONSD to identify elevated ICP was 93.33%, and its negative predictive value was 45.00%. ONSD measurement accuracy was 83.16%. Conclusions: Increased ICP can be accurately predicted by bedside USG measurement of ONSD and can be a valuable adjunctive tool in the management of TBI patients.

Abstract PDF

The sixth cranial nerve (CN VI) is a rare site of complication associated with spinal anesthesia and can produce secondary symptoms of ocular muscle palsy. A 38-year-old man was admitted to the emergency department with complaint of diplopia and limited lateral gaze in the first week after endoscopic urological surgery under spinal anesthesia. Isolated unilateral CN VI palsy was considered after excluding differential diagnoses. Ocular palsy and diplopia regressed with conservative treatment during follow-up, and the patient was discharged. This article aims to show that CN VI palsy is a rare complication of spinal anesthesia, which can be observed in the emergency department.

Abstract PDF

Critical illness neuromyopathy (CINM) is a sporadically reported disease in the setting of an intensive care unit developing in the process of managing a critical illness. The disease primarily affects the motor and sensory axons and results in severe limb weakness rendering ventilator weaning extremely difficult. We report a case of CINM after cardiac valve surgery. Quadriplegia developed after the operation and resolved slowly over the following 2 months. The patient was discharged home free of neurologic symptoms.

Abstract PDF

In most cases, patients admitted to an intensive care unit (ICU) have suffered from severe trauma, undergone major surgery or been treated for a serious medical illness. Although they often experience more intense pain than general ward patients, they are frequently unable to communicate their experiences to health care providers, thus preventing accurate assessment and treatment of their pain. If appropriate measures are not taken to treat pain in critically ill patients, stress response or sympathetic overstimulation can lead to complications. The short-term consequences of untreated pain include higher energy expenditure and immunomodulation. Longer-term, untreated pain increases the risk of post-traumatic stress disorder. Because pain is quite subjective, the accurate assessment of pain is very difficult in the patients with impaired communication ability. The current most valid and reliable behavioral pain scales used to assess pain in adult ICU patients are the Behavioral Pain Scale and the Critical-Care Pain Observation Tool. Once pain has been accurately assessed using these methods, various pharmacologic and non-pharmacologic therapies should be performed by the multidisciplinary care team. Accurate assessment and proper treatment of pain in adult ICU patients will improve patients outcome, which reduces the stress response and decreases the risk of post-traumatic stress disorder.

Abstract PDF: BACKGROUND
Early prediction of neurologic outcome is important to patients treated with therapeutic hypothermia after hypoxic brain injury. Hypoxic brain injury patients may have poor neurologic prognosis due to increased intracranial pressure. Increased intracranial pressure can be detected by optic nerve sheath diameter (ONSD) measurement in computed tomography (CT) or ultrasound. In this study, we evaluate the relation between neurologic prognosis and optic nerve sheath diameter measured in brain CT of hypoxic brain injury patients.
METHODS
We analyzed the patient clinical data by retrospective chart review. We measured the ONSD in initial brain CT. We also measured and calculated the gray white matter ratio (GWR) in CT scan. We split the patients into two groups based on neurologic outcome, and clinical data, ONSD, and GWR were compared in the two groups.
RESULTS
Twenty-four patients were included in this study (age: 52.6 +/- 18.3, 18 males). The mean ONSD of the poor neurologic outcome group was larger than that of the good neurologic outcome group (6.07 mm vs. 5.39 mm, p = 0.003). The GWR of the good neurologic outcome group was larger than that of the poor outcome group (1.09 vs. 1.28, p = 0.000). ONSD was a good predictor of neurologic outcome (area under curve: 0.848), and an ONSD cut off > or = 5.575 mm had a sensitivity of 86.7% and a specificity of 77.8%.
CONCLUSIONS
ONSD measured on the initial brain CT scan can predict the neurologic prognosis in cardiac arrest and hanging patients treated with therapeutic hypothermia.

Abstract PDF: Bilateral vocal cord paralysis may occur as a result of mechanical injury during neck surgery, nerve compression by endotracheal intubation or mass, trauma, and neuromuscular diseases. However, only a few cases of bilateral vocal cord paralysis have occurred following short-term endotracheal intubation. We report a case of bilateral vocal cord paralysis subsequent to extubation after endotracheal intubation and mechanical ventilation due to severe pneumonia for 2 days.

Abstract PDF: A 73-year-old man was scheduled for the surgical reduction of fractured femur which occurred ar 3 months ago by the accident. The mental status of the patient was stuporous (Glasgow coma scale: 5) due to the complication of the head trauma. We performed nerve blocks (femoral, sciatic, lateral femoral cutaneous, and illiohypogastric nerve blocks) for the surgical reduction of left femur with 55 ml of 0.25% ropivacaine. The electroencephalography was monitored continuously during the 4 hour operation as well as monitoring the hemodynamic and respiratory parameters. The operation was performed successfully and the patient recovered uneventfully.

Abstract PDF: Phrenic nerve palsy is a well-known complication following cardiac surgery in children. The incidence is approximately 1~2%. In infants and young children, it often causes a life-threatening respiratory distress. They must be treated with mechanical ventilation in the ICU. Many patients with phrenic nerve injury who is impossible to wean from a ventilator are candidates of diaphragmatic plication. Diaphragmatic plication is performed to restore the normal pulmonary parenchymal volume by replacing the diaphragm to its proper location. This is a case of 2-months-old infant who had phrenic nerve palsy after the removal of cavernous lymphangioma of the chest. He underwent 4 operations to remove the mass and to have pericardiotomy. We tried to wean him from the ventilator but failed several times in the ICU. After 4th operation, right diaphragmatic elevation was noted from the chest X ray. Phrenic nerve palsy was confirmed with fluoroscopy and he underwent diaphragmatic plication on 42 days after his 4th operation. Three days after the diaphragmatic plication, weaning was successfully carried out.

Abstract PDF: BACKGOUND: The barrier can be altered by a number of insults to the brain (e.g., hypertension, freezing, trauma, drug). But the effect of the blood brain barrier distruction immediately after the neural change is unknown. In the present study, we focused on the BBBD after cervical sympathetic chain block.
METHODS
13 male Sprague-Dawley rats were divided into 2 groups. Group 1 (N=7) was blocked with 0.5% bupivacaine on the right cervical sympathetic chain and group 2 (N=6) was blocked with 0.5% bupivacaine on the bilateral cervical sympathetic chain. All rats received 37degrees C, 25% mannitol (1.75 g/kg) via right carotid artery and then, the effect of cervical sympathetic chain block on blood-brain barrier disruption of four cerebral compartment using 99mTc-human serum albumin and Evans blue was evaluated.
RESULTS
Both groups showed blood-brain barrier disruption and there was no significant difference between group 1 and group 2 in the anterior and posterior hemisphere of the right side brain. But group 2 showed significant blood-brain barrier disruption than group 1 in anterior and posterior hemisphere of the left brain (p<0.01).
CONCLUSIONS
This results suggest that cervical sympathetic chain block can increase the degree of mannitol-induced blood-brain barrier disruption via neural arch or blood flow change.
