Ultrasound for diagnostic and procedural purposes is becoming a standard in daily clinical practice including anaesthesiology and peri-operative medicine. The project of European Society of ...Anaesthesiology (ESA) Task Force for the development of clinical guidelines on the PERioperative uSE of Ultra-Sound (PERSEUS) project has focused on the use of ultrasound in two areas that account for the majority of procedures performed routinely in the operating roomvascular access and regional anaesthesia. Given the extensive literature available in these two areas, this paper will focus on the use of ultrasound-guidance for vascular access. A second part will be dedicated to peripheral nerve/neuraxial blocks. The Taskforce identified three main domains of application in ultrasound-guided vascular cannulationadults, children and training. The literature search were performed by a professional librarian from the Cochrane Anaesthesia and Critical and Emergency Care Group in collaboration with the ESA Taskforce. The Grading of Recommendation Assessment (GRADE) system for assessing levels of evidence and grade of recommendations were used. For the use of ultrasound-guided cannulation of the internal jugular vein, femoral vein and arterial access, the level evidence was classified 1B. For other accesses, the evidence remains limited. For training in ultrasound guidance, there were no studies. The importance of proper training for achieving competency and full proficiency before performing any ultrasound-guided vascular procedure must be emphasised.
Context. Approximately 1 in 20 patients undergoing the percutaneous cardiac intervention (PCI) experience severe procedure-related access-site (A-S) pain. The multimodal pain management model (MPM) ...can reduce the intensity and prevalence of pain and this approach was not investigated in the postprocedural pain management area. To address this, a randomized controlled trial was conducted in Hospital of Lithuanian University of Health Sciences Kauno klinikos in 2018. Methods. 137 patients who underwent PCI procedure via radial artery were randomly assigned (1 : 1) to the control (CG, n = 68) and intervention (IG, n = 65) groups. IG received MPM (paracetamol, ibuprofen, and the arm physiotherapy), CG received pain medication “as needed.” Outcomes were assessed immediately after, 2, 12, 24, and 48 h, 1 week, and 1 and 3 months after PCI. The primary outcome was A-S pain prevalence and pain intensity numeric rating scale (NRS) 0–10. Results. Results showed that A-S pain prevalence during the 3-month follow-up period was decreasing. Statistically significant difference between the groups (CG versus IG) was after 24 h (41.2% versus 18.5, p=0.005), 48 h (30.9% versus 1.5%, p≤0.001), 1 week (25% versus 10.8%, p=0.042), 1 month (23.5% versus 7.7%, p=0.017) after the procedure. The mean of the highest pain intensity was after 2 h (IG-2.17 ± 2.07; CG-3.53 ± 2.69) and the lowest 3 months (IG-0.02 ± 0.12; CG-0.09 ± 0.45) after the procedure. A-S pain intensity mean scores were statistically significantly higher in CG during the follow-up period (Wilks’ λ = 0.84 F (7,125) = 3.37, p=0.002). Conclusion. In conclusion, MPM approach can reduce A-S pain prevalence and pain intensity after PCI. More randomized control studies are needed.
Background
This is a prospective, double-blind observational study in which different types of analgesia and its effect on postoperative pain reduction in patients undergoing craniotomy for brain ...tumor removal were compared.
Methods
The study included 141 adult craniotomy patients that were randomly separated into three equal groups. A group with scalp nerve blockade (B) and wound infiltration (I) received 0.25% bupivacaine combined with 1% lidocaine and 1:200,000 epinephrine. One gram of paracetamol and 2 mg/kg ketoprofen were administered intravenously (IV) after skin closure in a group with systemic analgesia (S). Pain intensity was evaluated after 1, 3, 6, and 24 h postoperatively using a visual analogue scale (VAS). The amount of rescue analgesia (ketorolac, paracetamol, and pethidine) and the duration for its first requirement were recorded.
Results
One hundred and forty-one patients were included in the study. The main pain scores were significantly lower in the groups with regional anesthesia compared to group S in the first hours post-surgery (p < 0.05). Significantly lower pain scores were observed in the group with a scalp nerve blockade compared to the group with systemic analgesia or wound infiltration after 24 h (p < 0.05). Regional anesthesia ensured a stable analgesic effect for all 24 h. Patients in groups B and I required significantly fewer rescue analgesics compared to patients in group S. The duration for the requirement of the first rescue analgesia was significantly longer in groups B and I compared to group S (p = 0.000).
Conclusions
The results of our study show that most patients experience pain in the early postsurgical hours. Regional analgesia could help reduce the incidence and severity of pain after a craniotomy and the amount of rescue analgesia used in this group of patients.
Acute postoperative pain is one of the most undesirable experiences for a patient in the postoperative period. Many options are available for the treatment of postoperative pain. One of the methods ...of multimodal analgesia is a combination of opioids and adjuvant agents, such as ketamine. The aim of this study was to evaluate the effect of a pre-incisional single injection of low-dose ketamine on postoperative pain after remifentanil infusion in patients undergoing laparoscopic gastric bypass or gastric plication surgery.
The prospective, randomized, double-blinded and placebo-controlled trial took place at the Hospital of the Lithuanian University of Health sciences KaunoKlinikos in 2015-2017. A total of 32 bariatric patients (9 men and 23 women) were randomly assigned to receive a single pre-incisional injection of ketamine (0.15 mg/kg (LBM)) (ketamine, K group) or saline (placebo, S group). Standardized protocol of anesthesia and postoperative pain management was followed for all patients. Postoperative pain intensity, postoperative morphine requirements, incidence of side effects and patients' satisfaction with postoperative analgesia were recorded.
Thirty-two patients undergoing bariatric surgery: 18 (56.25%; gastric bypass) and 14 (43.75%; gastric plication) were examined. Both groups did not differ in demographic values, duration of surgery and anesthesia and intraoperative drug consumption. Postoperative pain scores were similar in both groups (
= 0.105-0.941). Morphine consumption was 10.0 (7.0-12.5 mg) in group S and 9.0 (3.0-15.0 mg) in group K (
= 0.022). The incidence of side effects was similar in both groups (
= 0.412). Both groups demonstrated very high satisfaction with postoperative analgesia.
Pre-incisional single dose ketamine reduces postoperative opioids consumption, but does not have an effect of postoperative pain intensity and side effects after remifentanil infusions. Very high patient satisfaction is achieved if standard multimodal analgesia protocol with an individual assessment of pain and dosage of medications is followed.
During orthotopic liver transplantation, venous air embolism may occur due to iatrogenic injury of the inferior vena cava. However, venous air embolism followed by coagulopathy is a rare event. In ...this case report, we discuss a possible connection between venous air embolism and disseminated intravascular coagulation.
A 37-year-old male patient with chronic hepatitis B- and C-induced liver cirrhosis was admitted for orthotopic liver transplantation. During the dissection phase of the surgery, arterial blood pressure, heart rate, saturation and end-tidal carbon dioxide levels suddenly decreased, indicating the occurrence of venous air embolism. After stabilizing the patient's condition, various coagulation issues started developing. Venous air embolism-induced coagulopathy was handled by administering transfusions of various blood products. However, the patient's condition continued to deteriorate leading to a complete asystole.
This is a rare case of venous air embolism-induced disseminated intravascular coagulation. The real connection remains unclear as disseminated intravascular coagulation for end-stage liver disease patients can be induced by various causes during different stages of liver transplantation. Certainly, both venous air embolism and coagulopathy were significant and led to an unfavorable outcome. Further studies are needed to better understand the possible mechanisms and correlation between these two life-threatening complications.
Local anesthetic systemic toxicity (LAST) in children is extremely rare, occurring at an estimated rate of 0.76 cases per 10,000 procedures. However, among reported cases of LAST in the pediatric ...population, infants and neonates represent approximately 54% of reported LAST cases. We aim to present and discuss the clinical case of LAST with full clinical recovery due to accidental levobupivacaine intravenous infusion in a healthy 1.5-month-old patient, resulting in cardiac arrest necessitating resuscitation.
A 4-kilogram, 1.5-month-old female infant, ASA I, presented to the hospital for elective herniorrhaphy surgery. Combined anesthesia was planned, involving general endotracheal and caudal anesthesia. After anesthesia induction, cardiovascular collapse was noticed, resulting in bradycardia and later cardiac arrest with EMD (Electromechanical Dissociation). It was noticed that during induction, levobupivacaine was accidentally infused intravenously. A local anesthetic was prepared for caudal anesthesia. LET (lipid emulsion therapy) was started immediately. Cardiopulmonary resuscitation was carried out according to the EMD algorithm, which lasted 12 min until spontaneous circulation was confirmed and the patient was transferred to the ICU. In ICU, the girl was extubated the second day, and the third day she was transferred to the regular pediatric unit. Finally, the patient was discharged home after a total of five days of hospitalization with full clinical recovery. A four-week follow-up has revealed that the patient recovered without any neurological or cardiac sequelae.
The clinical presentation of LAST in children usually begins with cardiovascular symptoms because pediatric patients are already under general anesthesia when anesthetics are being used, as was the case in our case. Treatment and management of LAST involve cessation of local anesthetic infusion, stabilization of the airway, breathing, and hemodynamics, as well as lipid emulsion therapy. Early recognition of LAST as well as immediate CPR if needed and targeted treatment for LAST can lead to good outcomes.
: As the latest research encourages the ultrasound-guided infraclavicular central venous approach, due to the lateral puncture site displacement, in comparison to the anatomical landmark technique ...based on subclavian vein catheterization, the need to re-calculate the optimal catheter insertion length and possibly to rename the punctuated vessel emerges. Although naming a particular anatomical structure is a nomenclature issue, a suboptimal catheter position can be associated with multiple life-threatening complications and must be avoided. The main study objective is to determine the optimal catheter insertion length by the most proximal ultrasound-guided, in-plane infraclavicular central vein approach, to compare results with the anatomical landmark technique based on subclavian vein catheterization and to clarify the punctuated anatomical structure.
: 109 patients were enrolled in this study. All procedures were performed according to the same catheterization protocol. In order to determine optimal insertion length, chest X-ray scans with an existing catheter were performed. The definition of punctuated vessel was based on computer tomography and evaluated by radiologists. Independent predictors for optimal insertion length were identified, prediction equations were generated.
: The optimal catheter insertion length is approximately 1.5 cm longer than estimated by Pere's formula and can be accurately calculated based on anthropometric data. Computed tomography revealed: five cases with subclavian vein puncture and three cases with axillary vein puncture.
: Even the most proximal ultrasound-guided infraclavicular central vein access does not guarantee subclavian vein catheterization. A more accurate term could be infraclavicular central venous access, with the implication that the entry point could be through either subclavian or axillary veins. The optimal insertion length is approximately 1.5 cm deeper than the length determined for the anatomical landmark technique based on subclavian vein catheterization.
Background and Objectives: Early postoperative recovery after surgery is a key point for patients’ safety and comfort. Moreover, operating room turnover depends on recovery time. Our aim was to ...assess which method of remifentanil administration, manual (MI) or target-controlled infusion (TCI), could reduce patient time in recovery room. In this study, patients’ recovery times were registered and compared among the groups. Materials and Methods: We enrolled 31 morbidly obese patients in this prospective study. All of them had undergone bariatric surgery at the Hospital of Lithuanian University of Health Sciences Kauno Klinikos in 2020. Sevoflurane/remifentanil anaesthesia was performed for all patients. The patients were randomly assigned to the manual infusion (MI) (control group) or target-controlled infusion (TCI) group for the method of the administration of remifentanil. While the patients were waking up after the surgery, we recorded spontaneous breathing and airway reflexes recovery time, time of extubation, eye opening, recovery of orientation and beginning of the following oral command. For the TCI group, we also documented remifentanil concentrations in the blood (automatic infusion pump). Results: Patients did not differ in demographic values and duration of remifentanil infusion. We found that remifentanil consumption in the TCI group was lower, p = 0.02. Despite lower remifentanil consumption in the TCI group patients, they demonstrated longer total recovery time than the control group patiens: 14 (12–20) vs. 10 (6–16), p = 0.001. Conclusions: The study showed that, upon comparing the TCI method with MI, manual infusion produced better results in postoperative patient recovery. Additionally, higher doses of remifentanil were consumed using MI. In conclusion, the dosage recommended by highly qualified anaesthesiologists is favourable for morbidly obesity patients when compared to the TCI method.
Objectives. The aim of this study is to assess the prevalence and predictive factors for developing chronic access-site (A-S) pain after percutaneous coronary intervention (PCI) via radial artery ...access. Methods. Data of selected patients (n = 161) who underwent elective PCI were collected prospectively and analysed in 2020. Verbal analogue scale was used to evaluate pain intensity after 12, 24, and 48 h and 3 months after PCI. The univariate logistic regression analysis was used. Results. Pain prevalence decreased from 29% straight after PCI and 54% two hours later to 3.7% following 3 months after procedure. The predictors for A-S pain chronicity are diabetes (OR = 5.77 95% CI (1.07–31.08), p=0.041), hematoma (OR = 6.48, 95% CI (1.06–39.66), p=0.043), A-S hand neuropathy (OR = 19.93 95% CI (1.27–312.32), p=0.033), A-S pain immediately after PCI (OR = 14.60 95% CI (1.63–130.27), p=0.016), after 12 h (OR = 17.2 95% CI (1.60–185.27), p=0.019), 24 h (OR = 48 95% CI (4.87–487), p=0.01), and 48 h (OR = 23.46 95% CI (3.81–144.17), p=0.001), and pain intensity immediately after procedure (OR = 3.30 95% CI (1.65–6.60), p=0.001), after 2 h (OR = 2.56 95% CI (1.15–5.73), p=0.022), after 12 h (OR = 3.02 95% CI (1.70–5.39), p<0.001), after 24 h (OR = 3.58 95% CI (1.90–6.74), p<0.001), and after 48 h (OR = 2.89 95% CI (1.72–4.87), p<0.001). Pain control was performed with Ketoprofen and Ibuprofen as most used NSAIDs. 10 mg of Morphine intravenously was the choice from strong opioids if necessary. Conclusions. The prevalence of chronic A-S pain is 3.7%. Main predictive factors for the A-S pain chronicity are diabetes, hematoma, and persistent pain and pain intensity during 48 h period after PCI.
For many years the impact of pain on children has been underestimated. Nowadays it is known to cause a wide spectrum of negative consequences. Therefore, this article aimed to report the ...effectiveness and success of the patient-controlled wound infiltration (PCWI) – one of the most recent postoperative pain management approaches.
We carried out three cases of the PCWI technique for patients aged nine-to-ten years in the Hospital of Lithuanian University of Health Sciences Kaunas Clinics. During surgery, the leading surgeon placed a multi-holed catheter preperitoneally, which was then connected to patient-controlled analgesia (PCA) device containing a pump with the analgesic solution filled beforehand. After the surgery, the patients evaluated their pain scores using a visual analogical scale every 3 h up until the removal of the catheter.
The average pain score of all three patients did not exceed more than 3.5 points with an overall pain score tendency to decrease over time when PCWI was applied. Moreover, no analgesia nor catheter-related complications were observed.
PCWI showed to be a good pain-relieving, easily used, and applied method with no incidence of complications and no adverse effects of medications when applied for no longer than 48 hours.
