Factors related to post-thoracotomy pain following robotic-assisted thoracic surgery.

BACKGROUND: Robotic-assisted thoracic surgery (RATS) is a minimally invasive procedure; however, some patients experience persistent postoperative pain. This study aimed to investigate factors related to postoperative pain following RATS. METHODS: The data of 145 patients with lung cancer, who underwent RATS with a four-port (one in the sixth intercostal space [ICS] and three in the eighth ICS) lobectomy or segmentectomy between May 2019 and December 2022, were retrospectively analyzed. Factors associated with analgesic use for at least 2 months following postoperative pain (PTP group) were analyzed. RESULTS: Patients who underwent preoperative pain control for any condition or chest wall resection were excluded. Among the 138 patients, 45 (32.6%) received analgesics for at least 2 months after surgery. Patient height and transverse length of the thorax correlated with PTP in the univariate analysis (non-PTP vs. PTP; height, 166 vs. 160 cm; p < .001; transverse length of the thorax, 270 vs. 260 mm, p = .016). In the multivariate analysis, height was correlated with PTP (p = .009; odds ratio, 0.907; 95% confidence interval, 0.843-0.976). Height correlated with the transverse length of the thorax (r = .407), anteroposterior length of the thorax (r = .294), and width of the eighth ICS in the middle axillary line (r = .210) using Pearson's correlation coefficients. When utilizing a 165-cm cutoff value for height to predict PTP using receiver operating characteristic curve analysis, the area under the curve was 0.69 (95% confidence interval, 0.601-0.779). CONCLUSION: Short stature is associated with a high risk of postoperative pain following RATS.

Comparison of Postoperative Respiratory Function Between Patients After Thoracoscopic and Open Lobectomy.

Purpose: This study aimed to compare respiratory functions of patients after thoracoscopic lobectomy (TS) with those after thoracotomy (TR). Methods: This retrospective study was conducted in two centers, one of which adapted TS as a standard procedure in 2009 and the other performs it via TR. Data on patients who underwent lobectomy for congenital lung disease between 2009 and 2021 and underwent pulmonary function test (spirometry) were collected. Results: Ten patients underwent TS and 36 underwent TR. Distribution based on sex, prenatal diagnosis, pathological diagnosis, and resected lobe were similar between the two groups. The median [interquartile range] age at procedure in the TR group was significantly smaller than that in the TS group (13 [11-18] months versus 38 [13-79] months, P = .03). The procedure duration in the TR group was significantly shorter than that in the TS group (230 [171-264] minutes versus 264 [226-420] minutes, P = .02). Pulmonary function test was conducted at the age of eight in both groups, but the interval between the procedure, and the test was significantly shorter in the TS group (TR: 7 [5-8] years versus TS: 5 [2-7] years, P = .03). The ratio of forced vital capacity compared to predicted one (TR: 86.6 [76.6-95.3] versus TS: 88.7 [86.8-89.1], P = .58) and the ratio of forced expiratory volume in 1 second against that predicted (TR: 84.0 [80.5-88.7] versus TS: 88.7 [86.8-89.1], P = .08) were not significantly different between the two groups. Conclusions: Although TR was performed earlier than TS, respiratory function was similar between the two groups.

Fractures and other chest wall abnormalities after thoracotomy for esophageal cancer: A retrospective cohort study.

BACKGROUND: Chest pain following a thoracotomy for esophageal cancer is frequently reported but poorly understood. This study aimed to (1) determine the prevalence of thoracotomy-related thoracic fractures on postoperative imaging and (2) compare complications, long-term pain, and quality of life in patients with versus without these fractures. METHODS: This retrospective cohort study enrolled patients with esophageal cancer who underwent a thoracotomy between 2010 and 2020 with pre- and postoperative CTs (<1 and/or >6 months). Disease-free patients were invited for questionnaires on pain and quality of life. RESULTS: Of a total of 366 patients, thoracotomy-related rib fractures were seen in 144 (39%) and thoracic transverse process fractures in 4 (2%) patients. Patients with thoracic fractures more often developed complications (89% vs. 74%, p = 0.002), especially pneumonia (51% vs. 39%, p = 0.032). Questionnaires were completed by 77 after a median of 41 (P25 -P75 28-91) months. Long-term pain was frequently (63%) reported but was not associated with thoracic fractures (p = 0.637), and neither were quality of life scores. CONCLUSIONS: Thoracic fractures are prevalent in patients following a thoracotomy for esophageal cancer. These thoracic fractures were associated with an increased risk of postoperative complications, especially pneumonia, but an association with long-term pain or reduced quality of life was not confirmed.

Erector spinae plane block as an anesthesia technique for an emergent thoracotomy; a case report.

BACKGROUND: The erector spinae plane block (ESPB) is a novel regional block technique for pain management following thoracic surgeries. However, there are minimal cases in which the technique was used as the main anesthesia technique during surgery. CASE PRESENTATION: Here, we report the successful use of ESBP for applying anesthesia in a case during an emergent thoracotomy for performing pericardiotomy and loculated tamponade evacuation. CONCLUSIONS: Using ESPB with a higher concentration of local anesthetics, in this case, prepared appropriate anesthesia for performing an emergent thoracotomy while avoiding multiple needle insertions and the risk of further hemodynamic instability.

Analysis of Risk Factors for Postoperative Dysuria in Patients Undergoing Thoracotomy under General Anaesthesia.

BACKGROUND: Thoracotomy under general anaesthesia is one of the most difficult surgeries and is prone to result in postoperative complications. This study explored risk factors for postoperative dysuria in patients undergoing thoracotomy under general anaesthesia to provide a reference for the formulation and selection of subsequent clinical management programs. METHODS: Patients undergoing thoracotomy under general anaesthesia (n = 179) admitted to our hospital from June 2019 to June 2021 were selected. They were divided into dysuria group (n = 79) and normal urination group (n = 100) according to whether they had dysuria after surgery. Logistic regression analysis was conducted to explore risk factors affecting postoperative dysuria. RESULTS: Univariate analysis showed that dysuria was related to gender, age, surgical time, intraoperative and postoperative infusion volume, usage time of analgesic pump and retention time of urethral catheter (p < 0.001). Logistic regression analysis showed that male, age ≥60 years, surgical time ≥120 min, intraoperative infusion volume >1200 mL, postoperative infusion volume >800 mL, analgesic pump usage time ≥18 h and urethral catheter retention time of ≥72 h were risk factors for postoperative dysuria. CONCLUSIONS: The occurrence of postoperative dysuria in patients undergoing thoracotomy under general anaesthesia is related to gender, age, surgical time, intraoperative infusion volume, postoperative infusion volume, usage time of analgesic pump and retention time of urethral catheter. Clinical attention should be given to this patient group, and targeted intervention measures should be implemented.

Five-Year Sustained Impact of a Thoracic Enhanced Recovery After Surgery Program.

BACKGROUND: Our thoracic enhanced recovery program (ERP) decreased the use of postoperative morphine equivalents and hospital costs 1 year after implementation at our tertiary center. The sustainability and potential increasing benefit of this program were evaluated. METHODS: From 2015 to 2021, we prospectively analyzed the outcomes of patients who underwent elective pleural, pulmonary, or mediastinal operations at our institution. Patients were separated on the basis of the incision (video-assisted thoracoscopic surgery [VATS] or thoracotomy). The ERP protocol was initiated on May 1, 2016, and includes preoperative education, carbohydrate loading, opioid-sparing analgesia, conservative fluid management, protective ventilation, and early ambulation. Outcomes of patients before (2015, pre-VATS and pre-thoracotomy) and after (May 1, 2016, to December 31, 2021, ERP-VATS and ERP-thoracotomy) ERP implementation were compared. RESULTS: The cohort included 1079 patients (pre-ERP era, n = 224 [21%]; ERP era, n = 855 [79%]). There was a median reduction of 1.5 hospital days per patient for ERP-thoracotomy and 1 hospital day per patient for ERP-VATS. Median postoperative morphine equivalents decreased in both groups (125 vs 45 mg, in ERP-thoracotomy; 84 vs 23 mg, ERP-VATS; P < .001), as did total admission cost ($32,118 vs $23,775, ERP-thoracotomy; $17,367 vs $11,560, ERP-VATS; P < .001). Median total fluid balance during the hospital stay decreased significantly. Rates of postoperative atrial fibrillation and urinary retention decreased across both subgroups. CONCLUSIONS: ERP for thoracic surgery is sustainable and has been demonstrated to improve patient outcomes, to decrease opioid use, and to lower hospital costs. Therefore, it has the potential to become the standard of care.

Treatment Patterns and Postoperative Activities of Daily Living in Patients with Non-small Cell Lung Cancer: A Retrospective Study Using Nationwide Health Services Utilization Data in Japan.

BACKGROUND: The number of older patients with cancer has been increasing. This study aimed to determine the proportion of postoperative decline in activities of daily living (ADL), hospital mortality rate, home healthcare services use, and adjuvant chemotherapy treatment patterns of patients with early-stage non-small cell lung cancer (NSCLC) across age groups. METHODS: We analyzed health service utilization data of patients aged ≥ 40 years diagnosed with clinical stage I or II NSCLC in 2015 who underwent thoracoscopy or thoracotomy. The Barthel index was used to determine the proportions of patients aged 40-64, 65-74, ≥ 75 years who experienced a decline in the ADL of ≥ 10 points at postoperative discharge compared to the ADL at admission. RESULTS: Overall, 19,780 patients were analyzed. The proportion of patients with ADL decline slightly increased with increasing age: 1.1%, 1.6%, and 3.5% after thoracoscopic surgery, and 1.4%, 2.8%, and 4.8% after thoracotomy among those aged 40-64, 65-74, and ≥ 75 years, respectively. The hospital mortality rate and proportion of home healthcare services use was fewer than 10 cases, or < 2%. The unexpected readmission rate was slightly higher among those aged ≥ 75 years (3.7% for thoracoscopic surgery, 4.7% for thoracotomy) than among those aged 40-64 years (1.8% for thoracoscopic surgery, 2.5% for thoracotomy). CONCLUSION: The difference in the proportion of patients with ADL decline between those aged 40-64 and ≥ 75 years was approximately 3%. This study provides practical information for clinicians involved in the care of older patients who undergo thoracic surgery.

Negative pressure dressings and the impact on pain management on thoracic incisions in patients undergoing oesophagectomy: a pilot study.

BACKGROUND: Pain control is recognised as a crucial post-operative measure for patients undergoing oesophagectomy with a thoracotomy incision for oesophageal cancer, where ineffective breathing due to pain is directly correlated with increased morbidity. The analgesic benefits of negative pressure wound therapy (NPWT) appear to be a relatively new and emerging finding. This pilot study aims to investigate the effects of NPWT on post-operative pain control and determine the feasibility of a larger trial. METHOD: Ten consecutive patients undergoing oesophagectomy were prospectively enrolled to have a PREVENA Incision Management System placed over a closed thoracotomy wound. This dressing was changed at post-operative day 5 and removed after day 10. Post-operative morbidity was recorded and analgesia was prescribed by the Acute Pain Service who were blinded to the study aims. Analgesia requirements were recorded in oral morphine equivalents (OME) and compared to 30 patients that had previously undergone oesophagectomy via thoracotomy. RESULTS: One patient was withdrawn from the study and there was no significant differences in patient demographics. The study group had less average daily analgesia requirements and reduced overall reported pain. Patients in the study group were less likely to develop pneumonia (44% and 57%) and less likely to require re-operation for complications of their surgery (0% and 10%). CONCLUSION: This pilot study shows reduced post-operative analgesia requirements and reduced morbidity when using NPWT over a closed thoracotomy wound, and affirms the feasibility of a future randomized control trial.

[Postoperative pulmonary torsion after upper lobectomy by thoracotomy]. / L'image du mois. Torsion pulmonaire en post-opératoire après lobectomie supérieure par thoracotomie.

The aim of this case report is to describe a lobar torsion after elective pulmonary resection. This is a rare but potentially fatal condition in which the lung rotates on its own axis. Although this condition may occur spontaneously, it most often follows lobectomy. Early diagnosis and prompt surgical intervention are essential to prevent complications. Treatment is surgical, and involves repositioning the lung in a physiological position. However, the presence of ischaemic lesions may lead to the resection of the lung portion concerned.

Le but de cet article est de décrire le cas d'une torsion pulmonaire survenue après une résection pulmonaire élective. C'est une affection rare, mais potentiellement mortelle, qui se traduit par une rotation du poumon sur son propre axe. Bien que cette affection puisse survenir de manière spontanée, elle apparaît le plus souvent dans les suites d'une lobectomie. Un diagnostic précoce et une intervention chirurgicale rapides sont essentiels afin de prévenir les complications. Le traitement est chirurgical et consiste à repositionner le poumon en position physiologique. Toutefois, la présence de lésions ischémiques peut conduire à une résection plus large de la portion pulmonaire concernée.

Video-assisted thoracic surgery or thoracotomy for lung cancer surgery in obese patients? An analysis of the European Society of Thoracic Surgeons database.

OBJECTIVES: There is a lack of evidence on whether perioperative outcomes differ in obese patients after video-assisted thoracic surgery (VATS) or open lobectomy. We queried the European Society of Thoracic Surgeons database to assess morbidity and postoperative length of hospital stay in obese patients submitted to VATS and open pulmonary lobectomy for non-small-cell lung cancer. METHODS: We collected all consecutive patients from 2007 to 2021 submitted to lobectomy through VATS or thoracotomy with a body mass index greater than or equal to 30. An intention-to-treat analysis was carried out. Primary outcomes were morbidity rate, mortality and postoperative length of stay (LOS). Differences in outcomes were assessed through univariable, multivariable-adjusted and propensity score-matched analysis. RESULTS: Out of a total of 78 018 patients submitted to lung lobectomy, 13 999 cases (17.9%) were considered in the analysis, including 5562 VATS lobectomies and 8437 thoracotomy lobectomies. The VATS group showed a lower complication rate (23.2% vs 30.2%, P < 0.001), mortality (0.8% vs 1.5%, P < 0.001) and postoperative LOS (median 5 vs 7 days, P < 0.001). After propensity score matching, the VATS approach confirmed a lower complication rate (24.7% vs 29.7%, P = 0.002) and postoperative LOS (median 5 vs 7 days, P < 0.001). Moreover, these results were consistently observed when analyzing the severe obese subgroup (body mass index 35-39.9) and morbid obese subgroup (body mass index ≥40). CONCLUSIONS: In obese patients with non-small cell lung cancer, VATS lobectomy was found to be associated with improved postoperative outcomes than open lobectomy. Consequently, it should be considered the approach of choice for the Obese population.

Bupivacaine combined with morphine for patient-controlled epidural analgesia after thoracotomy: high volume and low concentration vs. low volume and high concentration.

OBJECTIVE: In this prospective randomized controlled study, we aimed to evaluate the effects of the administration of equal doses of bupivacaine and morphine (BM) at high volume and low concentration (HV-LC) or low volume and high concentration (LV-HC) on the number of drugs consumed, pain scores and side effects. PATIENTS AND METHODS: We randomized 64 patients who underwent thoracotomy into two groups. Group 1 received a solution prepared with 0.12% bupivacaine and 0.05 mg/cc morphine, administered with a basal infusion rate of 4 cc/h, a 2-cc bolus dose, and a 30-minute lockout time. Group 2 received a solution prepared with 0.48% bupivacaine and 0.2 mg/cc morphine, administered with a basal infusion rate of 1 cc/h, a 0.5-cc bolus dose, and a 30-minute lockout time. We compared patient-controlled epidural analgesia (PCEA) usage doses, pain scores, sensory and motor block, hemodynamic effects, side effects, and patient satisfaction in the postoperative periods. RESULTS: An increase in drug consumption with PCEA was found in the first 24 hours postoperatively in Group 2 (p<0.05). Resting visual analog scale (VAS) scores were statistically significantly higher at hours 2, 28, 32, 36, 44 and coughing VAS scores were also higher at hours 2 and 20 in Group 2. Heart rates in Group 2 were lower than in Group 1 at hours 16, 24, 44 and 48 (p<0.05). The cephalic spread of the sensory block in Group 1 was more extensive (p<0.05). The groups demonstrated no significant differences regarding side effects and patient satisfaction (p>0.05). CONCLUSIONS: The HV-LC approach resulted in better analgesia, less drug consumption, and greater cephalic spread of sensory block than the LV-HC approach. Both applications were effective and safe in terms of analgesia and side effects.

Study protocol for a randomised controlled trial to investigate the effectiveness of thoracic epidural and paravertebral blockade in reducing chronic post-thoracotomy pain: 2 (TOPIC 2).

BACKGROUND: Thoracotomy is considered one of the most painful surgical procedures and can cause debilitating chronic post-surgical pain lasting months or years postoperatively. Aggressive management of acute pain resulting from thoracotomy may reduce the likelihood of developing chronic pain. This trial compares the two most commonly used modes of acute analgesia provision at the time of thoracotomy (thoracic epidural blockade (TEB) and paravertebral blockade (PVB)) in terms of their clinical and cost-effectiveness in preventing chronic post-thoracotomy pain. METHODS: TOPIC 2 is a multi-centre, open-label, parallel group, superiority, randomised controlled trial, with an internal pilot investigating the use of TEB and PVB in 1026 adult (≥ 18 years old) patients undergoing thoracotomy in up to 20 thoracic centres throughout the UK. Patients (N = 1026) will be randomised in a 1:1 ratio to receive either TEB or PVB. During the first year, the trial will include an integrated QuinteT (Qualitative Research Integrated into Trials) Recruitment Intervention (QRI) with the aim of optimising recruitment and informed consent. The primary outcome is the incidence of chronic post-surgical pain at 6 months post-randomisation defined as 'worst chest pain over the last week' equating to a visual analogue score greater than or equal to 40 mm indicating at least a moderate level of pain. Secondary outcomes include acute pain, complications of regional analgesia and surgery, health-related quality of life, mortality and a health economic analysis. DISCUSSION: Both TEB and PVB have been demonstrated to be effective in the prevention of acute pain following thoracotomy and nationally practice is divided. Identification of which mode of analgesia is both clinically and cost-effective in preventing chronic post-thoracotomy pain could ameliorate the debilitating effects of chronic pain, improving health-related quality of life, facilitating return to work and caring responsibilities and resulting in a cost saving to the NHS. TRIAL REGISTRATION: NCT03677856 [ClinicalTrials.gov] registered September 19, 2018. https://clinicaltrials.gov/ct2/show/NCT03677856 . First patient recruited 8 January 2019.

Survival outcomes and surgical morbidity based on surgical approach to pulmonary metastasectomy in pediatric, adolescent and young adult patients with osteosarcoma.

BACKGROUND: Thoracotomy is considered the standard surgical approach for the management of pulmonary metastases in osteosarcoma (OST). Several studies have identified the advantages of a thoracoscopic approach, however, the clinical significance of thoracotomy compared to thoracoscopy is yet to be evaluated in a randomized trial. AIMS: The primary aim was to determine the survival outcomes in OST patients based on surgical approach for pulmonary metastasectomy (PM) and secondary aim was to assess the post-operative morbidities of OST PM through various surgical approaches. MATERIALS AND METHODS: We conducted a single institution retrospective study to compare survival outcomes and surgical morbidity according to the surgical approach of the management of pulmonary metastases in patients with OST. RESULTS: Sixty-one patients with OST underwent PM. Twenty-one patients were metastatic at diagnosis and underwent PM during primary treatment; nine had thoracotomy, six thoracoscopy, and six combined thoracoscopy with thoracotomy (CTT). Forty-three patients with first pulmonary relapse or progression underwent PM; 18 had thoracotomy, 16 thoracoscopy and nine CTT. There was no difference in survival between surgical approaches. There were significantly more postoperative morbidities associated with thoracotomy for initial PM (pain and postoperative chest tube placement), and for PM at first relapse (pneumothoraces, pain, Foley catheter use and prolonged hospitalizations). CONCLUSION: Our study demonstrates that patients with OST pulmonary metastases have comparable poor outcomes despite varying surgical approaches for PM. There were significantly more postoperative morbidities associated with thoracotomy for PM. Surgical bias and other competing risks could not be assessed given the limitations of a retrospective study and may be addressed in a prospective trial evaluating surgical approach for PM in OST.

Pain management after thoracic surgery or chest trauma.

Accidental or surgically induced thoracic trauma is responsible for significant pain that can impact patient outcomes. One of the main objectives of its pain management is to promote effective coughing and early mobilization to reduce atelectasis and ventilation disorders induced by pulmonary contusion. The incidence of chronic pain can affect more than 35% of patients after both thoracotomy and thoracoscopy as well as after chest trauma. As the severity of acute pain is associated with the incidence of chronic pain, early and effective pain management is very important. In this narrative review, we propose to detail systemic and regional analgesia techniques to minimize postoperative pain, while reducing transitional pain, surgical stress response and opioid side effects. We provide the reader with practical recommendations based on both literature and clinical practice experience in a referral level III thoracic trauma center.

[Intraoperative and early surgical complications after VATS lobectomy]. / Intraoperatsionnye i rannie khirurgicheskie oslozhneniya pri torakoskopicheskikh lobektomiyakh.

OBJECTIVE: To improve the results of thoracoscopic anatomic lung resections (lobectomy) via reducing the incidence of intraoperative and early surgical complications. MATERIAL AND METHODS: The study enrolled 479 patients who underwent thoracoscopic lobectomy. We determined the main criteria of complications: injury of vascular structures with severe bleeding, damage of the bronchi and adjacent organs. RESULTS: Potentially life-threatening conditions requiring additional surgical manipulations (bleeding in 35 patients, bronchial trauma in 3 patients) were diagnosed in 7.9% (38/479) of cases. Vascular injury with severe bleeding occurred in 7.3% of patients (n=35). Three patients had bronchial trauma (7.9%). We stopped bleeding without thoracotomy in 48.5% (17/35) of patients. In 51.5% (18/35) of cases, emergency thoracotomy was performed. CONCLUSION: The problem of safety is still urgent despite widespread thoracoscopy in lung resections. Knowledge of the factors contributing to complications and working out appropriate algorithm of actions are of great importance.

Potential harms of emergency department thoracotomy in patients with persistent cardiac arrest following trauma: a nationwide observational study.

Emergency department thoracotomy (EDT) was incorporated into traumatic out-of-hospital cardiac arrest (t-OHCA) resuscitation. Although current guidelines recommend EDT with survival predictors, futility following EDT has been demonstrated and the potential risks have not been thoroughly investigated. This study aimed to elucidate the benefits and harms of EDT for persistent cardiac arrest following injury until hospital arrival. This retrospective cohort study used a nationwide trauma registry (2019-2021) and included adult patients with t-OHCA both at the scene and on hospital arrival. Survival to discharge, hemostatic procedure frequency, and transfusion amount were compared between patients treated with and without EDT. Inverse probability weighting using a propensity score was conducted to adjust age, sex, comorbidities, mechanism of injury, prehospital resuscitative procedure, prehospital physician presence, presence of signs of life, degree of thoracic injury, transportation time, and institutional characteristics. Among 1289 patients, 374 underwent EDT. The longest transportation time for survivors was 8 and 23 min in patients with and without EDT, respectively. EDT was associated with lower survival to discharge (4/374 [1.1%] vs. 22/915 [2.4%]; adjusted odds ratio [OR], 0.43 [95% CI 0.22-0.84]; p = 0.011), although patients with EDT underwent more frequent hemostatic surgeries (46.0% vs. 5.0%; adjusted OR, 16.39 [95% CI 12.50-21.74]) and received a higher amount of transfusion. Subgroup analyses revealed no association between EDT and lower survival in patients with severe chest injuries (1.0% vs. 1.4%; adjusted OR, 0.72 [95% CI 0.28-1.84]). EDT was associated with lower survival till discharge in trauma patients with persistent cardiac arrests after adjusting for various patient backgrounds, including known indications for EDT. The idea that EDT is the last resort for t-OHCA should be reconsidered and EDT indications need to be deliberately determined.Trial registration This study is retrospectively registered at University Hospital Medical Information Network (UMIN ID: UMIN000050840).

Regional Anesthesia With Paravertebral Blockade Is Associated With Improved Outcomes in Patients Undergoing Minithoracotomy Cardiac Surgery.

OBJECTIVE: Severe postoperative pain has been shown to affect many patients following minimally invasive cardiac surgeries (MICS). Multimodal pain management with regional anesthesia, particularly by delivery of local anesthetics using a paravertebral catheter (PVC), has been shown to reduce pain in operations involving thoracotomy incisions. However, few studies have reported high-quality safety and efficacy outcomes of PVCs following MICS. METHODS: Patients who underwent MICS at Vancouver General Hospital between 2016 and 2019 (N = 123) were reviewed for perioperative opioid-narcotic use. Primary outcomes were postoperative opioid use and hospital length of stay (LOS). Statistical analyses were performed using univariate and multivariable regression models to determine independent risk factors. RESULTS: A total of 54 patients received routine systemic analgesia (control), 53 patients received a paravertebral catheter (PVC), and 16 patients received another mode of regional analgesia (non-PVC). The mean hospital LOS was significantly different in patients in the PVC group at 5.8 ± 2.0 days versus 8.3 ± 7.1 days in the control and 6.6 ± 2.3 days in the non-PVC group (P = 0.033). The percentage of patients who did not require postoperative oxycodone was significantly higher in the PVC group (48.1%), compared with the control (24.5%) and non-PVC (37.5%; P = 0.043) groups. CONCLUSIONS: The administration of regional anesthesia using PVCs was associated with reduced need for opioids and a shorter LOS. The reduction in postoperative opioids may reduce the risk of potential opioid dependency in this population. Future studies should involve randomized controlled trials with systematic evaluation of pain scores to verify current study results.

Is preoperative pulmonary rehabilitation effective in the postoperative period after lung resection?

Objective: Investigating the effects of the preoperative short term intensive pulmonary rehabilitation program applied for patients who have undergone lung resection by thoracotomy, on lung functions, complication rates and length of hospital stay during the postoperative period. Methods: A prospective randomized trial of sixty patients were enrolled who would undergo pulmonary resection by thoracotomy and were randomly divided in two groups. Intensive pulmonary rehabilitation was performed on these patients in the study group 3 hours a day throughout 7 days during the preoperative period. Groups were compared with respect to their spirometric pulmonary functions, respiratory parameters, blood gas parameters, complication rates and length of hospital stay. Results: Total incidence rate of complications in the patients from the control group significantly increased(p=0,028). When patients who underwent lobectomy and wedge resection were observed, length of hospital stay of those in the control group was seen to be statistically higher in comparison with the study group(p<0,05). Conclusion: We consider that it will be very beneficial to perform a short term and intensive pulmonary rehabilitation program on every patient possible who is planned to undergo thoracotomy and lobectomy or wedge resection treatment.

Chronic pain after posterolateral and axillary approaches to lung surgery: a monocentric observational study.

PURPOSE: Post-thoracotomy pain syndrome (PTPS) and chronic postsurgical neuropathic pain (CPNP) were evaluated 4 months after thoracic surgery whether the approach was a posterolateral (PL) incision or the less invasive axillary (AX) one. METHODS: Patients, 79 in each group, undergoing a thoracotomy between July 2014 and November 2015 were analyzed 4 months after surgery in this prospective monocentric cohort study. RESULTS: More PL patients suffered PTPS (60.8% vs. 40.5%; p = 0.017) but CPNP was equally present (45.8% and 46.9% in the PL and AX groups). Patients with PTPS have more limited daily activities (p < 0.001) but a similar psychological disability (i.e., catastrophism). Patients with CPNP have an even greater limitation of daily activities (p = 0.007) and more catastrophism (p = 0.0002). Intensity of pain during mobilization of the homolateral shoulder at postoperative day 6 (OR = 1.40, CI 95% [1.13-1.75], p = 0.002); age (OR = 0.97 [0.94-1.00], p = 0.022), and presence of pain before surgery (OR = 2.22 [1.00-4.92], p = 0.049) are related to the occurrence of PTPS; while, height of hypoesthesia area on the breast line measured 6 days after surgery is the only factor related to that of CPNP (OR = 1.14 [1.01-1.30], p = 0.036). CONCLUSION: Minimally invasive surgery was associated with less frequent PTPS, but with equal risk of CPNP. Pain before surgery and its postoperative intensity are associated with PTPS. This must lead to a more aggressive care of pain patients before surgery and of a better management of postoperative pain. CPNP can be forecasted according to the early postoperative height of hypoesthesia area on the breast line.
