Guillain-Barré Syndrome Following Lung Adenocarcinoma Surgery: A Case Report and Literature Review.

BACKGROUND Guillain-Barre syndrome (GBS) is a rare immune-mediated peripheral nerve disorder. Among non-infectious factors, surgery has been identified as a potential trigger of the disease. This report presents the case of a 74-year-old man who developed GBS 15 days after a right lower lobectomy for lung adenocarcinoma. CASE REPORT We present a case of a patient who was a former smoker who underwent uniportal video-assisted (U-VATS) right lower lobectomy for localized lung adenocarcinoma. Fifteen days after surgery, he exhibited bilateral lower-limb weakness, widespread paresthesia, and postural instability. Comprehensive diagnostic workup, including clinical assessment, serological tests, cerebrospinal fluid (CSF) analysis, and nerve conduction studies (NCS), confirmed the diagnosis. Notably, CSF analysis revealed albumin-cytological dissociation, with albumin 453.2 mg/L, protein 757 mg/L, glucose 67 mg/dl, 3 white blood cells (WBC)/uL, and polymorphonucleates (PMN) 33%. NCS demonstrated motor and sensory abnormalities. Prompt administration of intravenous immunoglobulins (IVIG) 2 g/kg daily for 5 days resulted in complete recovery within 3 months. CONCLUSIONS This case emphasizes the importance of prompt recognition and management of GBS as a postoperative complication. Neurological examination, neuroimaging, and electrophysiological studies are essential for accurate diagnosis. IVIG therapy remains a cornerstone in GBS management, with favorable outcomes observed in this case. Enhanced awareness among clinicians about the potential association between surgery and GBS is vital to prevent more serious complications and ensure optimal patient management. Further research is crucial to determine the precise pathogenesis and mechanisms of GBS following lung surgery.

I-gel® as airways management in a challenging adult tracheobronchial foreign body aspiration.

Tracheobronchial foreign body (TFB) aspiration is an uncommon but potentially life-threatening event. This case report discusses the successful extraction of a metallic screw aspirated by a 48-year-old woman with intellectual disability, using flexible bronchoscopy through the i-gel® laryngeal mask under general anesthesia. The i-gel® device proved effective in maintaining airway access and facilitating bronchoscopy, emphasizing its utility in challenging cases. The report underscores the significance of careful assessment, skillful intervention, and multidisciplinary teamwork in managing TFB aspirations, especially in uncooperative patients with comorbidities.

Rectus sheath block added to parasternal block may improve postoperative pain control and respiratory performance after cardiac surgery: a superiority single-blinded randomized controlled clinical trial.

BACKGROUND: The population undergoing cardiac surgery confronts challenges from uncontrolled post-sternotomy pain, with possible adverse effects on outcome. While the parasternal block can improve analgesia, its coverage may be insufficient to cover epigastric area. In this non-blinded randomized controlled study, we evaluated the analgesic and respiratory effect of adding a rectus sheath block to a parasternal block. METHODS: 58 patients undergoing cardiac surgery via median sternotomy were randomly assigned to receive parasternal block with rectus sheath block (experimental) or parasternal block with epigastric exit sites of chest drains receiving surgical infiltration of local anesthetic (control). The primary outcome of this study was pain at rest at extubation. We also assessed pain scores at rest and during respiratory exercises, opiate consumption and respiratory performance during the first 24 hours after extubation. RESULTS: The median (IQR) maximum pain scores (on a 0-10 Numeric Rate Scale (NRS)) at extubation were 4 (4, 4) in the rectus sheath group and 5 (4, 5) in the control group (difference 1, p value=0.03). Rectus sheath block reduced opioid utilization by 2 mg over 24 hours (IC 95% 0.0 to 2.0; p<0.01), reduced NRS scores at other time points, and improved respiratory performance at 6, 12, and 24 hours after extubation. CONCLUSION: The addition of a rectus sheath block with a parasternal block improves analgesia for cardiac surgery requiring chest drains emerging in the epigastric area.

Ultrasound Guided Parasternal Block for Perioperative Analgesia in Cardiac Surgery: A Prospective Study.

Ultrasound guided parasternal block is a regional anaesthesia technique targeting the anterior branches of intercostal nerves, which supply the anterior thoracic wall. The aim of this prospective study is to assess the efficacy of parasternal block to manage postoperative analgesia and reduce opioid consumption in patients undergoing cardiac surgery throughout sternotomy. A total of 126 consecutive patients were allocated to two different groups, receiving (Parasternal group) or not (Control group) preoperative ultrasound guided bilateral parasternal block with 20 mL of 0.5% ropivacaine per side. The following data were recorded: postoperative pain expressed by a 0-10 numeric rating scale (NRS), intraoperative fentanyl consumption, postoperative morphine consumption, time to extubation and perioperative pulmonary performance at incentive spirometry. Postoperative NRS was not significantly different between Parasternal and Control groups with a median (IQR) of 2 (0-4.5) vs. 3 (0-6) upon awakening (p = 0.07); 0 (0-3) vs. 2 (0-4) at 6 h (p = 0.46); 0 (0-2) vs. 0 (0-2) at 12 h (p = 0.57). Postoperative morphine consumption was similar among groups. However, intraoperative fentanyl consumption was significantly lower in the Parasternal group [406.3 ± 81.6 mcg vs. 864.3 ± 154.4, (p < 0.001)]. Parasternal group showed shorter times to extubation [(191 ± 58 min vs. 305 ± 72 min, (p)] and better performance at incentive spirometer with a median (IQR) of 2 raised balls (1-2) vs. 1 (1-2) after awakening (p = 0.04). Ultrasound guided parasternal block provided an optimal perioperative analgesia with a significant reduction in intraoperative opioid consumption, time to extubation and a better postoperative performance at spirometry when compared to the Control group.

The VL3 videolaryngoscope for tracheal intubation in adults: A prospective pilot study.

BACKGROUND: Videolaryngoscopy (VLS) is recommended by international guidelines for the management of difficult airways. We conducted an observational prospective pilot study to assess the efficacy of the new VL3 videolaryngoscope for routine tracheal intubation (TI) in adults; in terms of success rate, the number of attempts, and maneuver duration, including both normal and difficult airways. METHODS: This prospective observational pilot study comprised a sample of 56 adult patients undergoing elective general anesthesia. For each patient, we performed VLS by VL3 recording the following data: successful TI rate, number of attempts, time of intubation, time to glottis visualization, Cormack-Lehane grade (CL), need for external laryngeal pressure, and presence of post-laryngoscopy side effects. RESULTS: TI was successfully carried out in the totality of patients. In only 4 out of 56 cases, the VL3 offered a CL II. The first attempt intubation was achieved in 48 patients (85.7%). In one case, external laryngeal pressure was needed. No CL III or CL IV were observed. We did not find any significant difference between the predicted difficult airways sample and the rest of the population. CONCLUSION: VL3 videolaryngoscope showed to be an effective and safe device for routine TI, even in those patients with predicted difficult airway. More studies are needed to confirm our findings and verify its efficacy even in other settings.

Percutaneous closure of patent foramen ovale in a patient with situs viscerum inversus.

We describe the case of a patient with situs viscerum inversus totalis in whom we performed percutaneous closure of a patent foramen ovale. This case report may represent a further contribution to illustrate instrumental and interventional issues to consider in patients with situs viscerum inversus; it is also an example in which a background in embryology and congenital heart disease may aid cardiologists for the well-tolerated and effective diagnosis and treatment of adult patients with cardiac anomalies.
