The need of central vein cannulation has been increased since the increased case of critical patients and patients underwent high-risk patients. Supraclavicular approach of central vein cannulation is an alternative approach to central vein cannulation due to fewer anatomical variance, good longitudinal vein view, better visualization of needle during procedure, clear demarcation of landmarks, larger target area, better patient comfort, and fewer complications. This case study presents an ultrasound guided central vein cannulation using supraclavicular approach in 30 year old male patient diagnosed with septic shock, anemia, trombcytopenia, and electrolyte imbalance post laparotomy. The indication of central vein cannulation in the patient was to deliver volume resuscitation, to provide emergency vein access, to provide nutritional support, to deliver chemically caustic agents, and central vein pressure monitoring.

Abstract Background: Ultrasound-guided fine needle aspiration cytology (FNAC US) has been proven to be an accurate and efficient tool in thyroid nodule evaluation. Thyroid nodule aspiration can be acquired with either of two techniques: the short axis, in which only the tip of the needle is observed, and the long axis, in which the entire length of the needle is observed. Our retrospective study aimed to compare the adequacy of the two techniques. Methods: FNAC US was performed in 357 thyroid nodules between January 2019 and December 2019. Data on the technique and the diagnostic accuracy were collected. Results: A total of 181 nodules were aspirated using the long axis technique, and 176 nodules were aspirated using the short axis technique. The diagnostic adequacies of the long axis technique were significantly higher than those of the short axis technique. technique (93% versus 83%, respectively, p< 0.001). Conclusion: In our study, the long axis technique provided more accurate cytological evaluation than the short axis technique.

Abstract Background Airway anesthesia is pivotal for successful awake intubation provided either topically or by nerve blocks. The widespread use of ultrasonography allows anesthesiologists to evaluate complex and varied anatomy before needle insertion. This study aims to evaluate the effect of ultrasound-guided technique for the block of the internal branch of the superior laryngeal nerve in difficult airway patients in comparison to blind anatomical technique. Sixty patients aged 18–60 years, of either sex, with the American Society of Anesthesiologists’ physical status (ASA) I–II were divided into two groups 30 patients of each. Group (L): using anatomical landmark technique to bilateral block internal branch of the superior laryngeal nerve (ibSLN) with 1 mL 2% Lidocaine and group (U): using ultrasound technique to bilateral block the ibSLN with 1 mL 2% Lidocaine. Assessment of the excellence of airway anesthesia during intubation by using the 5 points grading scale, time for intubation, effects on hemodynamic variables, and evaluation of patient awareness of pain and discomfort during fiber-optic intubation using numerical rating scale were compared. Results The duration of tracheal intubation was shorter in the ultrasound group as compared to the anatomical group; also, patient comfort was significantly better in the ultrasound group besides the effect of tracheal intubation on hemodynamics which was significant with a higher peak value during intubation and post-intubation in the anatomical group compared to the ultrasound group. Conclusions This study concludes that an ultrasound-guided block of ibSLN used as a part of the preparation of the airway for awake fiber-optic intubation enhances the quality of airway anesthesia and patient tolerance during the procedure.

Objective. To investigate the effects of different doses of hydromorphone under the guidance of ultrasound on ropivacaine blocking the superior inguinal iliac fascia and postoperative analgesia. Methods. From January 2020 to June 2021, 90 American Society of Anesthesiologists (ASA) I-II patients undergoing elective total hip arthroplasty (THA) were selected and randomly divided into 3 groups, 30 patients in each one. Ultrasound-guided superior inguinal iliac fascia block was performed in the patients of the 3 groups before operation. The L group: 0.3% ropivacaine 30 ml; the H1 group: 0.3% ropivacaine + 25 μg/kg hydromorphone 30 ml; the H2 group: 0.3% ropivacaine + 50 μg/kg hydromorphone 30 ml. The time until the occurrence of pain, pain intensity, sufentanil remedial dose, the number of PCIA presses, and effective times were compared among the 3 groups. The VAS and Ramsay scores of 3 groups were recorded at 12 h, 24 h, 36 h, and 48 h after operation. Results. The time from the end of surgery to the appearance of pain in the H2 group was higher than that in the H1 group and the L group, and the time in the H1 group was higher than that in the L group ( P < 0.05 ). The VAS score in the H2 group was lower than that in the H1 group and the L group, and the VAS score in the H1 group was lower than that in the L group ( P < 0.05 ). The VAS scores of 12 h, 24 h, 36 h, and 48 h after operation in the H2 group were lower than those of the H1 group and the L group, and the H1 group was lower than the L group ( P < 0.05 ). The Ramsay scores at 12 h, 24 h, 36 h, and 48 h after operation in the H2 group and the H1 group were higher than those in the L group ( P < 0.05 ), and the difference was not statistically significant in the H2 group and the H1 group ( P > 0.05 ). The remedial dosage of sufentanil, times of PCIA compression, and effective times in the H2 group were lower than those in the H1 group and the L group, and the level in the H1 group was lower than that in the L group ( P < 0.05 ). The incidence rates of adverse reactions in the L group, the H1 group, and the H2 group were 13.33%, 23.33%, and 30.00%, respectively. There was no significant difference in the incidence rate of adverse reactions among the 3 groups ( P > 0.05 ). Conclusion. 25 μg/kg and 50 μg/kg hydromorphone used in the ultrasound-guided superior inguinal iliac fascia block can enhance the time effect of ropivacaine and improve analgesic effects, with good safety. In addition, time effect and analgesic effect of 50 μg/kg hydromorphone in enhancing ropivacaine were more obvious.

Background: Epidural block placement in pediatric patients is technically challenging for anesthesiologists. The use of ultrasound (US) for the placement of an epidural catheter has shown promise. We compared landmark-guided and US-guided lumbar or lower thoracic epidural needle placement in pediatric patients.Methods: This prospective, randomized, comparative trial involved children aged 1–6 years who underwent abdominal and thoracic surgeries. Forty-five children were randomly divided into two groups using a computer-generated random number table, and group allocation was performed by the sealed opaque method into either landmark-guided (group LT) or real-time ultrasound-guided (group UT) epidural placement. The primary outcome was a comparison of the procedure time (excluding US probe preparation). Secondary outcomes were the number of attempts (re-insertion of the needle), bone contacts, needle redirection, skin-to-epidural distance using the US in both groups, success rate, and complications.Results: The median (interquartile range [IQR]) time to reach epidural space was 105.5 (297.0) seconds in group LT and 143.0 (150) seconds in group UT; P = 0.407). While the first attempt success rate was higher in the UT group (87.0% in UT vs. 40.9% in LT; P = 0.004), the number of bone contacts, needle redirections, and procedure-related complications were significantly lower. Conclusions: The use of US significantly reduced needle redirection, number of attempts, bone contact, and complications. There was no statistically significant difference in the time to access the epidural space between the US and landmark technique groups.

Abstract Delivery of enteral nutrition in critical infants post-paediatric cardiac surgery is sometimes hampered, necessitating direct feeding into the small intestine. This study is highlighting the role of ultrasound-guided post-pyloric feeding tube insertion performed by the paediatric cardiac ICU intensivist in critically ill infants. Methods: We carried out a prospective pilot observational experimental study in peri-operative cardiac infants with feeding intolerance between 2019 and 2021. Feeding tube insertion depends on a combination of ultrasound and gastric insufflation with air-saline mixture. Insertion was confirmed by bedside abdominal X-ray. Results: Out of 500 peri-operative cardiac infants, 15 needed post-pyloric feeding tube insertion in median 15 postoperative day. All were under 6 months of age with average weight of 3 ± 0.2 kg. Median Risk Adjustment for Congenital Heart Surgery Categories was 4. Median insertion time was 15 minutes. No complications have been reported. First pass success rate was 87%, while a second successful insertion attempt was needed in 2 cases (13%). Target daily calorie intake was achieved within average of 3.5 ± 0.4 days. Mean post-pyloric feeding tube stay was 20 ± 3 days. Out of 15 infants, 3 patients died, 1 patient needed gastrostomy tube, and 11 patients were discharged home on oral feeds. Conclusions: Ultrasound-guided post-pyloric feeding tube insertion using gastric insufflation with air-saline mixture in peri-operative cardiac infants with feeding intolerance is a useful and practical bedside tool, and it can be performed by a trained paediatric cardiac ICU intensivist. It may have potential positive effects on morbidity and outcome.

Abstract Background Examinations based on lung tissue specimen can play a significant role in the diagnosis for critically ill and intubated patients with lung infiltration. However, severe complications including tension pneumothorax and intrabronchial hemorrhage limit the application of needle biopsy. Methods A refined needle biopsy technique, named bronchus-blocked ultrasound-guided percutaneous transthoracic needle biopsy (BUS-PTNB), was performed on four intubated patients between August 2020 and April 2021. BUS-PTNB was done at bedside, following an EPUBNOW (evaluation, preparation, ultrasound location, bronchus blocking, needle biopsy, observation, and withdrawal of blocker) workflow. Parameters including procedure feasibility, sample acquisition, perioperative conditions, and complications were observed. Tissue specimens were sent to pathological examinations and microbial tests. Results Adequate specimens were successfully obtained from four patients. Diagnosis and treatment were correspondingly refined based on pathological and microbial tests. Intrabronchial hemorrhage occurred in patient 1 but was stopped by endobronchial blocker. Mild pneumothorax happened in patient 4 due to little air leakage, and closed thoracic drainage was placed. During the procedure, peripheral capillary hemoglobin oxygen saturation (SPO2), blood pressure, and heart rate of patient 4 fluctuated but recovered quickly. Vital signs were stable for patient 1–3. Conclusions BUS-PTNB provides a promising, practical and feasible method in acquiring tissue specimen for critically ill patients under intratracheal intubation. It may facilitate the pathological diagnosis or other tissue-based tests for intubated patients and improve clinical outcomes.
