Background : Intraoperative fluid management based on pulse pressure variation has shown potential to reduce postoperative pulmonary complications (PPCs) and improve clinical outcomes in various surgical settings. However, its efficacy and safety have not been assessed in patients undergoing thoracic surgery with one-lung ventilation. Methods : Patients scheduled for pulmonary lobectomy using uniportal video-assisted thoracic surgery approach were randomly assigned to two groups. In the PPV group, fluid administration was guided by the pulse pressure variation parameter, while in the near-zero group, it was guided by conventional hemodynamic parameters. The primary outcome was the partial pressure of oxygen (PaO 2 )/ fraction of inspired oxygen (FiO 2 ) ratio 15 min after extubation. The secondary outcomes included extubation time, the incidence of postoperative pulmonary complications in the first three postoperative days, and the length of hospital stay. Results : The PaO 2 /FiO 2 ratio did not differ between the two groups (364.48 ± 38.06 vs. 359.21 ± 36.95; p = 0.51), although patients in the PPV group ( n = 44) received a larger amount of both crystalloids (1145 ± 470.21 vs. 890 ± 459.31, p = 0.01) and colloids (162.5 ± 278.31 vs 18.18 ± 94.68, p = 0.002) compared to the near-zero group ( n = 44). No differences were found in extubation time, type and number of PPCs, and length of hospital stay. Conclusions : PPV-guided fluid management in thoracic surgery requiring one-lung ventilation does not improve pulmonary gas exchange as measured by the PaO 2 /FiO 2 ratio and does not seem to offer clinical benefits. Additionally, it results in increased fluid administration compared to fluid management based on conventional hemodynamic parameters.

Introduction: Difficult intubation is the situation when a skilled anesthetist has difficulties to manage airway using face mask, laryngoscopy, supraglottic device, tracheal intubation, surgery. Videolaryngoscope and flexible fibroscope (FFS) represent valid alternatives for difficult airway management, with some limitations. However, literature lacks of studies about the efficacy of the combined use of videolaryngoscope and FFS., Case Report: We report a case of a man, with glottic lesion, who needs surgery under general anesthesia. Anesthesiologic pre-operative evaluation revealed that he's a difficult intubation case. So, in a supine position, intubation was performed on first attempt by videolaryngoscope combined with FFS. On post-op, no signs of injuries due to intubation have been found., Discussion: In 2022, the American Society of Anesthesiologists defined the guidelines to manage difficult intubation: based on patient' anatomical and clinical feature and anesthetist' skills, several intubation procedures could be used. Each procedure has pros and cons., Conclusion: It's the first case of anticipated difficult intubation in adult man that was intubated under general anesthesia by using videolaryngoscope combined with FFS. We demonstrated that this procedure is safe and useful in case of difficult airway and recommended in case of laryngeal lesions that hinder the visualization of glottic plane., Competing Interests: Conflict of interest statement The authors declare no conflict of interest., (Copyright © 2024 The Author(s).

Background: To evaluate the analgesic efficacy of continuous erector spinae plane block(c-ESPB) and serratus anterior plane block(c-SAPB) versus the intercostal nerve block (ICNB) in Uniportal-VATS in terms of pain control, drug consumption, and complications., Methods: Ninety-three consecutive patients, undergone one of the three peripheral nerve blocks after Uniportal-VATS, were prospectively enrolled. A 1:1 propensity score matching was used to minimize bias., Results: C-ESPB and c-SAPB groups had no difference in morphine request upon awakening compared to ICNB. A higher VAS-score was recorded in c-ESPB compared to ICNB in the first 12 h after surgery. A significantly lower consumption of paracetamol in II postoperative day (p.o.d.) and tramadol in I and II p.o.d. was recorded in the c-ESPB group compared to the ICNB group. A higher dynamic VAS score was recorded at 24 h and 48 h in the ICNB group compared to the c-SAPB. No difference was found in safety, VAS-score and drug consumption between c-ESPB and c-SAPB at any given time, except for a higher tramadol request in c-SAPB in II p.o.d., Conclusions: C-ESPB and c-SAPB appear to have the same safety and analgesic efficacy when compared between them and to ICNB in Uniportal-VATS approach. C-ESPB showed a delayed onset of analgesic effect and a lower postoperative drug consumption compared to ICNB.

Background and Objectives: There are no clinical studies that compare epidural infusion of ropivacaine and levobupivacaine in patients undergoing lung surgery. The aim of this prospective, randomized double-blind study was to evaluate the efficacy and safety of two commercially available solutions of ropivacaine (0.2% w/v) and levobupivacaine (0.125% w/v) when administered by continuous epidural infusion together with sufentanil in patients undergoing lung surgery., Methods: After obtaining informed consent, 54 patients, ASA physical status I-III undergoing lung resection, were enrolled. Patients were randomly assigned to two groups in which analgesia was performed by continuous thoracic epidural infusion of ropivacaine 0.2% w/v (Group R) or levobupivacaine 0.125% w/v (Group L) with or without sufentanil 1 microg mL(-1). After a test and a loading dose of each drug for the respective group, continuous epidural infusion, set at 5 mL h(-1), began. General anaesthesia was standardized. In the recovery room, patients were provided with intravenous morphine patient-controlled analgesia. Visual analogue scale at rest and when coughing, rescue patient-controlled analgesia morphine amount, haemodynamics, sensory and motor block, sedation, nausea and vomiting, patient satisfaction score, were evaluated within 48 h., Results: The two groups were similar regarding patient characteristics, quality of analgesia, level of sensory block, morphine consumption and satisfaction score. Postoperative haemodynamic profile was stable in all the patients. Minor side-effects occurred with a similar incidence. Motor block was not seen., Conclusions: Equivalent volumes of ropivacaine (0.2% w/v) and levobupivacaine (0.125% w/v) provided similar static and dynamic analgesia with similar incidence of minor side-effects after thoracotomy.

Aim: Combining an opioid with peridural local analgesia is an excellent technique to control post-operative pain. Sufentanil is a widely used opioid agent, but its optimal dosage has not yet been defined. In this study we wanted to determine the best dose of epidural sufentanil in major surgery., Methods: Before the operation, 45 major abdominal surgery patients received blended anesthesia through an epidural chest catheter. The patients were randomized into 3 groups of 15 subjects according to different sufentanil doses [0.2% ropivacaine combined with sufentanil at a dose of 0.5 microg/ml(-1), 0.75 microg/ml(-1), or 1 microg/ml(-1) (groups A, B and C, respectively)] administered through an epidural chest catheter connected to an elastometric pump (5 ml/h) for the first 36 postoperative hours. The level of postoperative analgesia in motion and at rest was measured using an analog visual scale (VAS-R, VAS-I)., Results: Analgesia was best in group A, and similar in groups B and C; 2 cases of pruritus were noted in group C. The VAS-I scores were <3 across all 3 patient groups., Conclusion: Epidural analgesia is an efficacious and reliable technique. The combination of 0.2% ropivacaine and 0.75 microg/ml(-1) sufentanil was found to be the optimum choice between analgesic efficacy and minor side effects, which correlated with the higher dose of sufentanil given to group C.

A case of wound botulism in a 41-year old man is reported. The patient had accidently been wounded when he fell on an iron bar. Some days later he developed typical clinical manifestations of botulism. Wound botulism was confirmed by detection and quantification of type B botulinal toxin in the serum. Ventilatory supportive care was necessary and botulinal antitoxin was not given. The patient was hospitalized for 30 days and recovery was complete.
