Inadvertent Puncture of Dilated Right Ventricle During Transversus Thoracic Muscle Plane Block: Lessons Learnt.

ABSTRACT: The transversus thoracic muscle plane (TTP) block is gaining widespread recognition in cardiac surgery, particularly in facilitating fast-tracking. Here, we report a case of inadvertent puncture of the right ventricle (RV) during the administration of ultra sound-guided (USG) TTP block in a 3-year-old child posted for atrial septal defect (ASD) closure and mitral valve repair. We also discuss the care that should be taken to avoid such complications and such cases require extra caution during TTP block.

A case report of atrial septal puncture "mistakenly" penetrated the aorta during left bypass radiofrequency ablation.

INTRODUCTION: Transseptal punctures (TSPs) are widely used in left atrium and left ventricle surgery. Accidental puncture of the puncture needle into the aorta is a rare complication that is rarely reported but has serious consequences. The appropriate management of this complication remains unclear. PATIENT CONCERNS: This report describes a case of a male with the chief complaint: paroxysmal palpitation for 1 year, aggravated for 1 month. DIAGNOSIS: The electrophysiological diagnosis was atrioventricular reentrant tachycardia caused by left-side bypass. INTERVENTIONS: Radiofrequency ablation of the heart was a necessary treatment and a TSP operation was needed, in which a puncture was mistakenly believed to have entered the aorta, a series of measures were taken urgently. Although the surgical procedure in this case was a false alarm, we still initiated a series of emergency plans. Emergency measures to address the complications were effectively implemented, and the emergency measures were promptly terminated after it was clear that complications had been misjudged. OUTCOMES: At last, it was confirmed that the angiogram was a pulmonary artery image, not an aorta image. Then the atrial septal puncture operation was successfully completed, and under the guidance of the Carto system, the ablation was successfully completed. Postoperative fluoroscopy showed no complications, such as pericardial effusion. After 2 years of follow-up, there was no reoccurrence of tachycardia, and there were no complications. It is crucial that emergency procedures are terminated in a timely manner after a clear miscarriage of performance. Although accidental puncture into the aorta is urgent and serious, performing a blockage or even thoracotomy in an emergency if complications are not clearly confirmed can cause further damage to the patient and would be a definitively wrong strategy. CONCLUSION: Strict and standardized TSP operations can avoid complications. Correct judgment of the authenticity of complications is crucial, and remedial measures that may cause further damage should not be blindly adopted. The retention of the aortic guide wire can provide convenient access for further differential diagnosis and remedial treatment.

Effect of photobiomodulation therapy on pain perception during anesthetic puncture of dental local anesthesia: A systematic review.

BACKGROUND: Local anesthetic puncture is often related to the experience of pain. This study aimed to systematically analyze the literature on changes in pain perception during the anesthetic puncture of dental local anesthesia after Photobiomodulation Therapy (PBMT). MATERIAL AND METHODS: An electronic search was performed in eight primary databases (Embase, LILACS, BBO, LIVIVO, MedLine via PubMed, SciELO, Scopus, and Web of Science) and three additional ones (EASY, Google Scholar, and OATD) to partially capture the "gray literature". The PICO strategy was used to identify randomized clinical trials evaluating the analgesic effect of PBMT in the anesthetic puncture site of dental local anesthesia compared to placebo or control groups, without restrictions on publication language and year. Two reviewers extracted the data and assessed the individual risk of bias of the eligible studies using the Cochrane Collaboration Risk of Bias Tool version 2.0. RESULTS: The electronic search found 3,485 records, of which eight met the eligibility criteria and were included in the qualitative synthesis. The studies were published from 2011 to 2022. None of the included studies had a low risk of bias. PBMT groups showed no significant difference in pain scores compared to placebo and control groups of most studies. CONCLUSION: Based on a low to very low certainty of evidence, PBMT seems to have no effect on pain perception during anesthetic puncture in patients undergoing dental local anesthesia.

The effect of the simulated intrauterine sound on behavioral and physiological indices of pain during capillary blood sampling for screening preterm infants: a randomized clinical trial study.

INTRODUCTION: Due to medical procedures, preterm infants are at high risk for side effects of pain. In this regard, heel lancing for capillary blood sampling is a common painful procedure. The present study was conducted to assess the effectiveness of a simulated intrauterine sound on behavioral and physiological indices of pain due to heel-prick blood sampling in preterm infants. METHODS: A double­blind randomized clinical trial (RCT) was conducted. The data were collected from September 23 to December 22, 2019. We measured the effect of a simulated intrauterine sound on changes in the behavioral and physiological parameters of pain (heart rate, SPO2) caused by heel lance that was measured 5 min before the intervention, during the sampling, and 5 min after the procedure. We measured behavioral pain by video recording the infants' faces and then the scoring neonatal infant pain scale (NIPS). Heart rate and SPO2 were measured using a pulse oximeter device. The data were analyzed using analysis of variance (ANOVA) and independent t­test in SPSS software version 20.0. RESULTS: Eighty infants were randomized (40 in each group). Mean scores NIPS during and after intervention were in the intervention group (3.55 ± 0.84, 95% CI: 3.30-3.80(, and (1.15 ± 0.84, 95%: 0.95-1.35) and in the control group (5.57 ± 0.95, 95% CI:5.30-5.85) and (3.00 ± 0.98) respectively. There were significant differences in scores of NIPS between the two study groups during (p < 0.001) and five min after heel lancing (p < 0.001). Mean scores of heart rate in the three phases of before, during, and five min after the intervention were respectively in the intervention group (127.57 ± 4.45, 95% CI:126.27-128.99), (131.07 ± 6.54, 95% CI:129.20-133.22), (128.45 ± 5.15, 95% CI:127.02-130.07) and in the control group (128.67 ± 4.57, 95% CI:127.32-130.07), (136.07 ± 7.24, 95% CI:133.90-138.37), and (132.42 ± 6.47, 95% CI:130.37-134.49). There were significant differences in heart rate between the intervention and the control group during (p = 0.002) and five min after the heel lance (p = 0.003). Mean scores of SPO2 in the three phases of baseline, during, and five min after the intervention were respectively in the intervention group (96.72 ± 0.93, 95% CI:96.42-97.00), (91.47 ± 1.46, 95% CI:91.05-91.92), (94.17 ± 1.03, 95% CI:93.22-94.00) and in the control group (96.6 ± 0.84, 95% CI:96.35-96.85), (91.5 ± 1.24, 95% CI:91.12-91.87), and (93.60 ± 1.27, 95% CI:93.85-94.50). CONCLUSION: This study showed that the simulated intrauterine sound reduces the behavioral pain and heart rate in the intervention group during and after heel lance. These results suggest using the method during the painful heel lancing to reduce pain parameters in preterm infants.

Golden bifid treatment regulates gut microbiota and serum metabolites to improve myocardial dysfunction in cecal ligation and puncture-induced sepsis mice.

Myocardial damage is a major consequence and a significant contributor to death in cases of sepsis, a severe infection characterized by a distinct inflammatory response and a potential threat to the patient's life. Recently, the effects of intestinal microbiota and serum metabolites on sepsis have garnered increasing attention. Herein, the effects of golden bifid treatment upon cecal ligation and puncture (CLP)-induced sepsis in mice as a model for myocardial dysfunction were explored. Our results demonstrated that golden bifid treatment partially improved myocardial dysfunction and apoptosis, cardiac inflammation and oxidative stress, and intestinal mucosal permeability and barrier dysfunction in CLP-induced sepsis mice. The intestinal microbiota diversity and abundance were also altered within sepsis mice and improved by golden bifid treatment. Mucispirillum schaedleri, Acinetobacter baumannii and Lactobacullus intestinalis were significantly correlated with heart damage markers, inflammatory factors, or oxidative stress indicators. Serum differential metabolite levels were also significantly correlated with these parameters. Altogether, golden bifid treatment might be an underlying approach for treating sepsis-induced myocardial dysfunction and highlight the underlying effect of intestinal microbiota and serum metabolites on the pathogenesis and treatment of sepsis-triggered myocardial dysfunction.

Mechanism of chronic iatrogenic CSF leak following dural puncture-ventral dural leak: case report.

BACKGROUND: Postdural puncture headache has been traditionally viewed as benign, self-limited, and highly responsive to epidural blood patching (EBP) when needed. A growing body of data from patients experiencing unintended dural puncture (UDP) in the setting of attempted labor epidural placement suggests a minority of patients will have more severe and persistent symptoms. However, the mechanisms accounting for the failure of EBP following dural puncture remain obscure. An understanding of these potential mechanisms is critical to guide management decisions in the face of severe and persistent cerebrospinal fluid (CSF) leak. CASE PRESENTATION: We report the case of a peripartum patient who developed a severe and persistent CSF leak unresponsive to multiple EBPs following a UDP during epidural catheter placement for labor analgesia. Lumbar MRI revealed a ventral rather than dorsal epidural fluid collection suggesting that the needle had crossed the thecal sac and punctured the ventral dura, creating a puncture site not readily accessible to blood injected in the dorsal epidural space. The location of this persistent ventral dural defect was confirmed with digital subtraction myelography, permitting a transdural surgical exploration and repair of the ventral dura with resolution of the severe intracranial hypotension. CONCLUSIONS: A ventral rather than dorsal dural puncture is one mechanism that may contribute to both severe and persistent spinal CSF leak with resulting intracranial hypotension following a UDP.

A Case Report of Radial Artery Pseudoaneurysm After Repeated Radial Puncture for Arterial Blood Gas.

Arterial blood gas, with subsequent radial arterial puncture as a simple access point, comprises a ubiquitous medical procedure in the diagnostic workup of patients admitted to the emergency department with dyspnea. Despite being a relatively safe and technically straightforward procedure, due to its considerable use, it is of vital importance to be able to promptly recognize its potential complications. We present the case of a 96-year-old female patient admitted to the emergency department with dyspnea and cough who underwent left radial arterial puncture for arterial blood gas. A total of three puncture attempts were performed until arterial blood was collected. Roughly two weeks upon observation, the patient was readmitted to the emergency department after the insidious appearance of a painful swelling in the left wrist, with progressive worsening since hospital discharge. On physical examination, a painful erythematous pulsatile swelling in the left wrist's volar aspect was observed, and further point-of-care ultrasound evaluation documented a cysticlike collection, communicating with the radial artery's lumen, and suggesting the probable diagnosis of iatrogenic radial pseudoaneurysm. The patient was hospitalized and underwent surgical resection of radial pseudoaneurysm, with subsequent arterial repair. Although severe complications from arterial blood gas have a low incidence rate, prompt diagnosis and management are required. Therefore, point-of-care ultrasound, as an additional diagnostic tool, may play a role in minimizing the risk of procedural complications.

Improving Arterial Puncture Success in Neonatal Patients Using Transillumination.

BACKGROUND: Arterial punctures are a common procedure used to obtain blood samples for lab tests that guide treatment of neonatal patients. These punctures can be painful and have associated risks, emphasizing the importance of keeping attempts to a minimum. PURPOSE: The purpose of this quality improvement initiative was to determine whether using transillumination to visualize arteries before and while obtaining a blood sample would improve outcomes in neonatal patients. METHODS: Quantitative data were collected pre- and postimplementation of education for the use of a transillumination device for arterial punctures on neonates in a level III neonatal intensive care unit (NICU). Outcomes followed included the success rate, average time to obtain a blood sample, and the average number of sticks to obtain a blood sample. Data were collected on 47 blood draw attempts in the control group (preimplementation) and 19 blood draw attempts in the experimental group (postimplementation). RESULTS: A statistical analysis concluded that the use of the studied transillumination device does positively affect the incidence of successful blood draws, particularly for the novice NICU nurse. In addition, the average number of sticks to obtain a blood sample significantly decreased in the experimental group. Finally, the average time to obtain a blood sample using the device was not impacted in this study. IMPLICATIONS FOR PRACTICE AND RESEARCH: Use of a transillumination device does appear to result in improved outcomes for arterial punctures in neonatal patients. More research is needed to confirm these findings due to the small sample size of the study.

Pediatricians' focus of sight at pain assessment during a neonatal heel puncture.

OBJECTIVE: To evaluate the focus of pediatricians' gaze during the heel prick of neonates. METHODS: Prospective study in which pediatricians wearing eye tracker glasses evaluated neonatal pain before/after a heel prtick. Pediatricians scored the pain they perceived in the neonate in a verbal analogue numerical scale (0=no pain; 10=maximum pain). The outcomes measured were number and time of visual fixations in upper face, lower face, and hands, in two 10-second periods, before (pre) and after the puncture (post). These outcomes were compared between the periods, and according to pediatricians' pain perception: absent/mild (score: 0-5) and moderate/intense (score: 6-10). RESULTS: 24 pediatricians (31 years old, 92% female) evaluated 24 neonates. The median score attributed to neonatal pain during the heel prick was 7.0 (Interquartile range: 5-8). Compared to pre-, in the post-periods, more pediatricians fixed their gaze on the lower face (63 vs. 92%; p=0.036) and the number of visual fixations was greater on the lower face (2.0 vs. 5.0; p=0.018). There was no difference in the number and time of visual fixations according to the intensity of pain. CONCLUSIONS: At bedside, pediatricians change their focus of attention on the neonatal face after a painful procedure, focusing mainly on the lower part of the face.

A rare complication: hydrophilic coating of puncture guide wire found floating in the pulmonary artery.

A 62-year-old woman with atrial fibrillation was admitted to Sichuan Provincial People's Hospital, and radiofrequency ablation therapy was planned.

Bloodletting puncture in the treatment of acute ischemic stroke: protocol for a mixed-method study of a multi-center randomized controlled trial and focus group.

This study is to investigate the effectiveness and safety of bloodletting puncture (BP) for acute ischemic stroke (AIS) when used in combination with standard treatment, as well as the patients' feelings and attitudes toward the treatment. This is a mixed method research which includes a multi-center, superiority, randomized controlled clinical trial, and focus group interview. A total of 360 AIS participants will be enrolled. They will be randomized into one of the following two groups for 7 d: (a) BP with standard treatment group (n = 180); (b) standard treatment group (n = 180). The primary outcome will be National Institute of Health stroke scale (NIHSS) score at day 7 after treatment. Secondary outcomes will be changes of Glasgow Coma Scale score, NIHSS score, mRS and Traditional Chinese Medicine syndrome score from baseline to 7, 14, and 30 d after treatment, recurrence rate and all-cause mortality rate within 30 d, and the safety assessments. The focus group will be conducted with a purposive sample of 1-2 acupuncturists and 1-2 patients respectively at each center at 7 and 30 d after treatment. We designed a mixed method study to evaluate the effect of BP, an acupuncture therapy for patients with AIS. If the findings of this study confirm the effectiveness of BP to reduce the NIHSS score and other related outcomes and patients are willing to accept the therapy, we believe this study will help the implementation of this therapy in clinical practice, and provide new evidence for the treatment of AIS.

[Dynamic indicators of the use of puncture method for the treatment of acute maxillary sinusitis in healthcare institutions of the city of Moscow]. / Dinamicheskie pokazateli primeneniya punktsionnogo metoda lecheniya ostrogo verkhnechelyustnogo sinusita v uchrezhdeniyakh zdravookhraneniya goroda Moskvy.

According to the statistical forms medical and preventive treatment centres (MPTC), the analysis of dynamic indicators of the treatment of patients with acute sinusitis (AS) in outpatient polyclinic centers (OPC) and ENT hospitals in Moscow for the period from 2017 to 2021 was carried out. The total number of visits to an otorhinolaryngologist in the OPC in Moscow for 2017-2021 amounted to 6 834 952 patients, including 245 172 patients with AS (3.6%).The total number of hospitalizations in the departments of otorhinolaryngology for the same period amounted to 184 735 patients, including 12 906 patients with AS (7%).The number of patients with AS who was consulted by an otorhinolaryngologist from 2017 to 2021 decreased by 18.2%, which can be explained by a change in the routing of patients with mild form of AS to general practitioners. An analysis of the dynamic indicators of maxillary sinus punctures carried out in the medical and preventive treatment centres (MPTC) in Moscow during the period from 2017 to 2021 showed that there was a redistribution of this manipulation from ENT hospitals to the OPC. At the same time, the proportion of patients requiring puncture treatment in the OPC for 2017-2019 was stable and amounted to 9.3%. However, since 2020, there has been an increase in this indicator by more than 2 times (21.7%), which probably indicates an increase in the treatment of patients with moderate forms of AS in the OPC. The frequency of maxillary sinus punctures that were performed in ENT hospitals in 2017-2019 amounted to 83.5%, in 2020-2021 decreased to 63.4%. The average number of maxillary sinus punctures per patient in ENT hospitals from 2017 to 2019 was 13.3. Since 2020, this value has decreased by about 2 times and has become equal to 8.5. The decrease in the number of maxillary sinus punctures that were performed in ENT hospitals is probably due to the fact that patients with severe and complicated forms of acute sinusitis hospitalized from 2020 to 2021 required more radical surgical treatment.

Indwelling Needle Puncture and Irrigation in the Conservative Treatment of Breast Abscess During Non-Lactation Period.

The objective of this study is to observe the effect of indwelling needle puncture and irrigation in the conservative treatment of breast abscesses in the non-lactation period. Non-lactating breast abscess patients were treated at the Daping Medical Breast Surgery Clinic, Chongqing. In the Incisive drainage group, 21 patients were treated with conventional incision and drainage. In the Indwelling needle group, 20 patients were treated by puncture and irrigation with a 20 G indwelling needle. The pain VAS scores and wound satisfaction in the Indwelling needle group were significantly lower than those in the Incisive drainage group (P < 0.001), and the cure time and complications were also significantly lower in the Indwelling needle group (P < 0.05). The cure rates of the two groups were similar (P > 0.05). There was a difference in the duration of illness, location, and number of pus cavities between the treatment failure and the treatment recovery (P < 0.05). However, there was no difference in the size of the pus cavity and the maximum amount of pus aspiration (P > 0.05). The indwelling needle can be used as an effective tool for puncture and irrigation of single breast abscess in a non-lactation period, potentially for non-invasive treatment of breast abscesses.

Stattic ameliorates the cecal ligation and puncture-induced cardiac injury in septic mice via IL-6-gp130-STAT3 signaling pathway.

AIM: Sepsis-induced cardiac dysfunction is the leading cause of higher morbidity and mortality with poor prognosis in septic patients. Our recent previous investigation provides evidence of the hallmarks of signal transducer and activator of transcription3 (STAT3) activation in sepsis and targeting of STAT3 with Stattic, a small-molecule inhibitor of STAT3, has beneficial effects in various septic tissues. We investigated the possible cardioprotective effects of Stattic on cardiac inflammation and dysfunction in mice with cecal ligation and puncture (CLP)-induced sepsis. MAIN METHODS: A polymicrobial sepsis model was induced by CLP in mice and Stattic (25 mg/kg) was intraperitoneally given at one and twelve hours after CLP operation. The cecum was exposed in sham-control mice without CLP. After 18 h of surgery, electrocardiogram (ECG) for anaesthized mice was registered followed by collecting of samples of blood and tissues for bimolecular and histopathological assessments. Myeloperoxidase, a marker of neutrophil infiltration, was assessed immunohistochemically. KEY FINDINGS: CLP profoundly impaired cardiac functions as evidenced by ECG changes in septic mice as well as elevation of cardiac enzymes, and inflammatory markers with myocardial histopathological and immunohistochemical alterations. While, Stattic markedly reversed the CLP-induced cardiac abnormalities and restored the cardiac function by its anti-inflammatory activities. SIGNIFICANCE: Stattic treatment had potential beneficial effects against sepsis-induced cardiac inflammation, dysfunction and damage. Its cardioprotective effects were possibly attributed to its anti-inflammatory activities by targeting STAT3 and downregulation of IL-6 and gp130. Our investigations suggest that Stattic could be a promising target for management of cardiac sepsis and inflammation-related cardiac damage.

Aloe-Emodin Ameliorates Cecal Ligation and Puncture-Induced Sepsis.

Sepsis remains a major challenge owing to its severe adverse effects and high mortality, against which specific pharmacological interventions with high efficacy are limited. Mitigation of hyperactive inflammatory responses is a key factor in enhancing the likelihood of survival in patients with sepsis. The Aloe genus has several health benefits, including anti-inflammatory properties. The toxicological implications of aloe-emodin (AE), extracted from various Aloe species, remain uncertain in clinical contexts. However, AE has been shown to inhibit inflammatory responses in lipopolysaccharide-induced mice, indicating its potential as a therapeutic approach for sepsis treatment. Nonetheless, there is a paucity of data regarding the therapeutic benefits of AE in the widely recognized cecal ligation and puncture (CLP)-induced sepsis model, which is commonly used as the gold standard model for sepsis research. This study demonstrates the potential benefits of AE in the treatment of CLP-induced sepsis and investigates its underlying mechanism, along with the efficacy of postoperative AE treatment in mice with CLP-induced sepsis. The results of this study suggest that AE can mitigate sepsis in mice by diminishing systemic inflammation and regulating the gut microbiota. The study provides novel insights into the molecular mechanisms underlying the anti-inflammatory effects of AE.

Risk Factors for Postoperative Puncture Site Bleeding after Interventional Treatment of Cerebrovascular Disease via Common Femoral Artery Puncture: A Retrospective Analysis of 710 Cases.

This study aimed to identify the risk factors associated with puncture site bleeding following percutaneous puncture of the common femoral artery during interventional treatment of cerebrovascular disease (CVD). A retrospective analysis was conducted on 710 patients who underwent interventional treatment for CVD via femoral artery puncture. Among them, 26 individuals (3.66%) experienced bleeding at the femoral artery puncture site. Binary logistic regression analysis was performed to identify risk factors for puncture site bleeding. The impact of salt bag compression on postoperative bleeding was evaluated in patients with intermediate to high bleeding risk scores. The bleeding group showed higher blood pressure, lower platelet counts, longer prothrombin time and activated partial thromboplastin time, as well as a higher prevalence of larger vascular sheath sizes and variations in the timing of anti-coagulant and anti-platelet therapy administration. The bleeding risk score was higher in the bleeding group, indicating its predictive value for bleeding risk. Higher bleeding risk score, unstable blood pressure, repeated puncture, and serious vascular conditions were significant risk factors for puncture site bleeding. Application of salt bag compression for a duration of 2 hours reduced postoperative puncture site bleeding in patients with intermediate to high bleeding risk scores. Our study identified several significant risk factors for puncture site bleeding after cerebral vascular intervention via femoral artery puncture, including the bleeding risk score, blood pressure, repeated puncture, and vascular conditions. Implementing salt bag compression as a preventive measure can help mitigate bleeding complications in these high-risk patients.

The effectiveness of the puncture channel plugging for reduction of complications after CT-guided percutaneous transthoracic needle biopsy.

The effect of plugging the puncture channel with a mixture of hemocoagulase injection on the complications of CT-guided percutaneous transthoracic need biopsy (PTNB) was discussed. The medical records of PTNB were retrospectively studied from June 2017 to May 2022. In the study, the puncture channel of 626 patients were blocked, while remain 681 patients' were not. The Mantel Haenszel method performed layered analysis and evaluated the correlation of adjusted confounding factors. The Odds Ratio and its 95% confidence interval were calculated using the Woof method. The incidence of high-level pulmonary hemorrhage was significantly reduced in patients with lesions ≤ 2 cm and different needle lengths. Patients with different pleural-needle tip angle and perineedle emphysema were blocked, and the incidence of pneumothorax and thoracic implants was significantly reduced. Through puncture channel plugging, the incidence of pulmonary hemorrhage, pneumothorax and thoracic catheterization of PTNB under CT guidance was reduced.
