Shoulder and arm pain: A “red herring” chief complaint in a smoker diagnosed with Pancoast-Tobías syndrome

Introduction: A Pancoast tumor is a rare apical lung cancer that can lead to a constellation of signs and symptoms known as Pancoast-Tobías syndrome, which involves ipsilateral shoulder and arm pain, Horner’s syndrome, and atrophy of the intrinsic hand muscles. As a Pancoast tumor progresses, it first invades the brachial plexus and causes unrelenting shoulder and arm pain in the C8-T2 nerve distributions. However, when evaluating this presenting symptom, it is often considered benign, especially in aging patients. Consequently, Pancoast-Tobías syndrome is easily misdiagnosed or delayed in diagnosis, resulting in poor prognosis, particularly for patients with advanced disease. Case Report: We present the case of an elderly Afro-Caribbean woman with a 24-pack-year smoking history who presented with unrelenting pain to the right shoulder and arm for two months. During that time, she visited multiple family physicians. Onset of pain coincided with a wasp sting that was complicated by a large local reaction. Despite clinical resolution of the inflammatory reaction, the pain persisted even with multi-modal oral analgesics. Detailed physical examination later revealed ipsilateral atrophy of the intrinsic hand muscles and focal chest findings concerning for an underlying consolidative lung process. This prompted diagnostic chest imaging, which identified a right-sided Pancoast tumor aggressively invading adjacent structures. She soon developed Horner’s syndrome, resulting in clinicoradiologic confirmation of Pancoast-Tobías syndrome. Conclusion: It is important to consider Pancoast-Tobías syndrome as an important differential of unrelenting shoulder and arm pain, even in the absence of pulmonary symptoms, in patients with risk factors for lung cancer, such as chronic smokers.

Diagnosis and treatment of 11 patients with cevical spondylotic amyotrophy

To explore clinical features, treatment methods and clinical effects of cervical spondylosis with proximal muscular atrophy. Eleven patients with proximal-type cervical spondylotic amyotrophy were retrospectively studied from September 2016 to November 2020, including 7 males and 4 females, aged 38 to 68 years old. Clinical symptoms, MRI and neuroelectrophysiological manifestations were analyzed, and patients were treated with conservative treatment or anterior cervical decompression fusion surgery, respectively. The efficacy was evaluated by manual muscle test (MMT) before and after treatment, and patients' satisfaction was followed up at the same time. All patients were followed up for 6 to 19 months. All 11 patients were unilateral, mainly manifested by atrophy of deltoid muscle, supraspinatus muscle and infraspinatus muscle, and may be accompanied by ipsilateral neck and shoulder pain at early stage. MRI showed lesions at C4,5, C5,6 segments were more common. Electrophysiological examination showed the affected muscle was denervated, and amplitude of compound muscle action potential (CMAP) of innervated nerve on the affected side was lower than that on the healthy side. All patients were obtained bone fusion. One patient who were underwent anterior cervical corpectomy and fusion (ACCF) occurred developed contralateral C5 nerve root paralysis after operation, which recovered completely after 10 weeks of symptomatic treatment. At 12 months after operation, the efficacy was evaluated according to MMT, 3 patients were treated conservatively, 2 patients excellent and 1 good;in 8 patients treated by operation, 3 patients were excellent, 4 good, and 1 moderate. The incidence of cervical spondylosis with proximal muscular atrophy is low, which is manifested as unilateral proximal muscle atrophy and may be accompanied by ipsilateral neck and shoulder pain in the early stage. Combined with MRI and neuroelectrophysiological examination, misdiagnosis could be reduced. In the early stage of disease, especially in the case of nucleus pulposus protrusion leading to nerve compression, conservative treatment could be taken. When the conservative treatment is ineffective or the pain cannot be tolerated, anterior decompression surgery is recommended, and the overall effect is satisfactory.

Incidence and risk factors of ipsilateral shoulder pain in patients after thoracic surgeries.

Ipsilateral shoulder pain (ISP) post-thoracotomy impairs the recovery in early postoperative period, the aetiology of which is unclear. We studied to find out the incidence and risk factors associated with ISP. We did a prospective observational study, wherein 296 patients scheduled for thoracic surgeries were enroled. Pain in the shoulder during activity was assessed using American Shoulder and Elbow Surgeons standardised assessment method. All potential predictors were analysed in a multivariable penalised logistic regression model, using ISP as the outcome variable. Of the 296 patients, 118 (39.8%) patients developed ISP. Of the 296 patients, 170 patients underwent thoracotomy and 110 underwent video-assisted thoracoscopic surgeries. The incidence of ISP was higher in thoracotomy patients (45.29%) compared to video-assisted thoracoscopic surgeries (32.7%). Majority of patients (43.2%) were aged more than 65 years, which was statistically significant as per univariate analysis (P = .007). The incidence of ISP was the highest at 41.89% among those who had lung cancer (n = 74), with disease involving right upper lobe and left upper lobe, 29% and 25.8%, respectively. The pain severity was moderate in 27.1% of patients during shoulder movements. Among the patients who had ISP, 77.1% expressed it as dull aching, whereas 21.2% described it as stabbing in nature. The incidence of ISP in those who underwent thoracic surgery was high and dull aching in nature, of mild to moderate intensity, commonly located on the posterior aspect of the shoulder. It was more common in those who underwent thoracotomy and more than 65 years of age.

Efficacy of Phrenic Nerve Block and Suprascapular Nerve Block in Amelioration of Ipsilateral Shoulder Pain after Thoracic Surgery: A Systematic Review and Network Meta-Analysis

Background and Objectives: Ipsilateral shoulder pain (ISP) is a common complication after thoracic surgery. Severe ISP can cause ineffective breathing and impair shoulder mobilization. Both phrenic nerve block (PNB) and suprascapular nerve block (SNB) are anesthetic interventions; however, it remains unclear which intervention is most effective. The purpose of this study was to compare the efficacy and safety of PNB and SNB for the prevention and reduction of the severity of ISP following thoracotomy or video-assisted thoracoscopic surgery. Materials and methods: Studies published in PubMed, Embase, Scopus, Web of Science, Ovid Medline, Google Scholar and the Cochrane Library without language restriction were reviewed from the publication's inception through 30 September 2022. Randomized controlled trials evaluating the comparative efficacy of PNB and SNB on ISP management were selected. A network meta-analysis was applied to estimate pooled risk ratios (RRs) and weighted mean difference (WMD) with 95% confidence intervals (CIs). Results: Of 381 records screened, eight studies were eligible. PNB was shown to significantly lower the risk of ISP during the 24 h period after surgery compared to placebo (RR 0.44, 95% CI 0.34 to 0.58) and SNB (RR 0.43, 95% CI 0.29 to 0.64). PNB significantly reduced the severity of ISP during the 24 h period after thoracic surgery (WMD -1.75, 95% CI -3.47 to -0.04), but these effects of PNB were not statistically significantly different from SNB. When compared to placebo, SNB did not significantly reduce the incidence or severity of ISP during the 24 h period after surgery. Conclusion: This study suggests that PNB ranks first for prevention and reduction of ISP severity during the first 24 h after thoracic surgery. SNB was considered the worst intervention for ISP management. No evidence indicated that PNB was associated with a significant impairment of postoperative ventilatory status.

Effect of Upper Arm Position Changes on the Occurrence of Ipsilateral Shoulder Pain After Single-Operator Port Thoracoscopy

BackgroundThe aim of this study was to explore the factors associated with the occurrence of ISP after VATS to reduce the incidence of ISP and improve patients' quality of life.MethodsThe data of patients were collected between June 2020 and August 2020 in the Department of Lung Cancer Surgery, Tianjin Medical University General Hospital. The angle of upper arm was measured intraoperatively. The patient's postoperative shoulder function was quantified using the Constant-Murley shoulder function rating score. The proportional hazards model was applied to identify multiple influence factors.ResultsA total of 140 eligible patients met criteria. At postoperative day 3, only the age influenced patients' shoulder pain. At postoperative day 14, univariate and multivariate logistic regression analyses showed that age (odds ratio [OR]: 1.098 [1.046-1.152]; P < 0.001) and upper arm Angle A (OR: 1.064 [1.011-1.121]; P = 0.018) were independent risk factors for low shoulder function scores. However, height was its protective factor (OR: 0.923 [0.871-0.977]; P = 0.006). At postoperative day 42, univariate and multivariate logistic regression analyses showed that age (OR: 1.079 [1.036-1.124]; P < 0.001) was a risk factor for low shoulder function scores, and height (OR: 0.933 [0.886-0.983]; P = 0.009) was its protective factor. In contrast, upper arm Angle B was not statistically associated with low shoulder function scores (P>0.05). In addition, the reduction in ipsilateral Shoulder scores after surgery was higher in patients with more than 113° of angle A (P = 0.025).ConclusionISP was closely related to the angle of anterior flexion of the upper arm on the patient's operative side intraoperatively. The increase in the degree of postoperative shoulder injury is more pronounced for an anterior flexion angle of >113°. Therefore, we recommend that the angle of anterior flexion of the upper extremity should be <113° intraoperatively.

The clinical and subjective outcomes associated with spinal manipulation: A case study

Spinal manipulation (SM) has been documented to have various physiological effects, of which the research literature has started to reflect over the past decade. This case study was designed with intent to further investigate these findings. A 31 year old woman with experience of lifting weights and working a very physical job presented with ipsilateral right-sided lower neck and shoulder pain (C7-T4, right trapezius, and right scapula area) and bilateral low back pain (L1-L5 and S.I joint area). Following the examination, a differential diagnosis list was decided on with the input of multiple doctors and therapists. The primary treatment was SM over a time span of 6 months. The patient displayed significant results. Objective testing through a follow-up range of motion (ROM) examination showed an increase in ROM and a spinal examination presented a reduction in local muscle tightness. In addition, subjectively, the patient reported a significant reduction in pain, an increase in movement confidence, and ability. The results of this case study suggest that SM in conjunction with patient education has a significant positive effect on the patient’s reduction of pain, local muscle tightness and increase in ROM, and patient movement ability and confidence. Further studies are required to isolate the specific effects of SM in a high-powered study and clinical setting.

The Development of the Arm Fixation Method to Prevent Ipsilateral Shoulder Pain in Patients Undergoing Lung Resection

PurposeThe aim of the present study was to investigate the efficacy of a new upper limb fixation method—body pillow position for preventing postoperative ipsilateral shoulder pain (ISP) in patients undergoing lung resection. DesignAn experimental study design was used. MethodsWe conducted two comparisons (group A: the previous position using the arm fixation device; group B: the body pillow position) at random and examined an arm fixation method that is effective for ISP prophylaxis in patients undergoing surgery in the lateral decubitus position. FindingsWe approached 87 patients, two were excluded, and, thus, 85 were randomly assigned to group A (n = 43) or group B (n = 42). No significant differences were observed in the frequency of ISP between groups A and B (25.6% vs 26.2%). The intensity of ISP between both groups was analyzed by a repeated-measures analysis of variance and was shown to decrease over time in 22 patients (P = .010). The intensity of ISP on postoperative days 0 to 3 was slightly lower in group B than in group A (P = .158). Risk factors for ISP were the duration of surgery (odds ratio, 1.01; 95% confidence interval, 1.00 to 1.01) and pre-existing shoulder stiffness (odds ratio, 5.15; 95% confidence interval, 1.07 to 24.83). ConclusionsThere was no significance in the frequency of ISP between group A and group B. The intensity of ISP on postoperative days 0 to 3 was lower in group B than in group A, although there was no significant difference. It is important perspective for perioperative care providers to prevent ISP for early postoperative recovery and improvement of postoperative quality of life. These results suggested that we must consider a better position for preventing postoperative ISP in patients undergoing lung resection.

CLINICAL FEATURES AND OUTCOMES OF LITTLE LEAGUE ELBOW IN YOUNG ATHLETES

Background:As participation and specialization in youth sports has increased, so too has the incidence of overuse conditions, such as medial epicondyle apophysitis, or Little League Elbow (LLE). Hypothesis/ Purpose: The study purpose was to assess the demographic features, clinical presentation, management, and outcomes of a population of skeletally immature athletes with this increasingly common, but understudied, condition.Methods:A retrospective analysis was performed of patients diagnosed with LLE between 2003 and 2017 at a tertiary-care pediatric hospital. All patients had open apophyses with a clinical history of repetitive overhead athletic activity and radiographic and/or physical exam findings consistent with LLE. Study variables were derived from the electronic medical record.Results:Three hundred seventeen subjects (mean age: 12.8 years, range 8yrs – 16yrs; 310 males, 98%) were identified. The vast majority were baseball players (n=310, 98%), though there were several tennis players (n=4, 1%) and football quarterbacks (n=3, 1%). Two-hundred sixty-eight patients (85%) presented with apophysitis, while 49 (15%) presented with acute avulsion fractures from throwing (with 84% reporting preceding medial elbow pain). The acute fracture patients are the subject of a separate study. In the apophysitis cohort, all of whom presented with medial elbow pain, other presenting findings/symptoms included decreased elbow range of motion (16%) and concomitant ipsilateral shoulder pain (13%). Amongst those with documented shoulder exams, a majority (55%) demonstrated glenohumeral internal rotation deficit (GIRD) with a significantly longer time from diagnosis to resolution of symptoms (p=0.025). All apophysitis patients were treated with rest (complete cessation 75%, relative rest/position change 25%). Mean follow up was 32 months (sd 33 months). Return to sports occurred at a median of 12 weeks from diagnosis (IQR 7wks – 18wks). Recurrence of elbow pain occurred a median of 24 months (IQR 11mo - 43mo) following initial diagnosis in 13% of patients, a sub-cohort with significantly longer duration of symptoms prior to index presentation (p=0.024). One patient also suffered a subsequent medial epicondylar avulsion fracture while throwing in the setting of non-compliance with recommended rest.Conclusion:Little League Elbow is most commonly seen in adolescent and pre-adolescent male pitchers but may rarely be seen in other overhead athletic sub-populations. Careful evaluation of the entire kinetic chain is critical to identify concomitant pathology such as GIRD, which may portend a prolonged recovery. Proper treatment is necessary to minimize recurrence and development of epicondyle avulsion fractures, which represent a potentially preventable, but severe variant of LLE.

Impact of regional analgesia techniques on the long-term clinical outcomes following thoracic surgery.

Continuous monitoring of clinical outcomes after thoracotomy is very important to improve medical services and to reduce complications. The use of regional analgesia techniques for thoracotomy offers several advantages in the perioperative period including effective pain control, reduced opioid consumption and associated side effects, enhanced recovery, and improved patient satisfaction. Postthoracotomy complications, such as chronic postthoracotomy pain syndrome, postthoracotomy ipsilateral shoulder pain, pulmonary complications, recurrence, and unplanned admission to the intensive care unit are frequent and may be associated with poor outcomes and mortality. The role of regional techniques to reduce the incidence of these complications is questionable. This narrative review aims to investigate the impact of regional analgesia on the long-term clinical outcomes after thoracotomy.

Efficacy of Phrenic Nerve Catheter in Ipsilateral Shoulder Pain After Thoracic Surgery

The mechanism of ipsilateral shoulder pain (ISP) after thoracic surgery remains unexplained definitively in the literature. Regional techniques targeting specific nerves more precisely will provide practitioners with a better understanding of the pain source. We report the case of a 51-year-old woman who underwent robotic-assisted plication of the right hemidiaphragm. ISP was adequately managed using a low-volume infusion through a continuous phrenic nerve block in addition to a thoracic epidural for her chest pain. ISP after thoracic surgery likely originates from diaphragm manipulation. Phrenic nerve blockade is a successful strategy that does not worsen subjective dyspnea in this setting.

Postoperative Pain Management and the Incidence of Ipsilateral Shoulder Pain After Thoracic Surgery at an Australian Tertiary-Care Hospital: A Prospective Audit

Ipsilateral shoulder pain (ISP) is a common but variably occurring(42%-85%) complication after thoracic surgery. Multiple potential treatments, including upper limb blocks, intrapleural local anaesthetic infiltration, and systemic opioids, have undergone trials, with limited efficacy. Phrenic nerve infiltration is a potential intervention that may prevent ISP. The aim of this study was to assess the incidence and severity of ISP after thoracic surgery at the authors' institution, where phrenic nerve infiltration is commonly used. Observational cohort study. A single- center study in a tertiary referral center in Brisbane, Australia. This study comprised all adult patients undergoing thoracic surgery at a tertiary- care referral center from May to July 2018. Surgical procedures were divided into open thoracotomy, video-assisted thoracic surgery (VATS) and VATS-guided mini-thoracotomy. The primary outcome was a comparison of incidence of ISP among the 3 types of surgical procedures. Data were analyzed using Stata (StataCorp), with significance testing by Kruskal-Wallis equality of populations rank test. A p value of < 0.05 was deemed significant. Sixty thoracic surgeries were performed during the audit period. Nineteen patients had thoracotomies performed for lobectomy or pneumonectomy, all of whom received phrenic nerve infiltration. The incidence of moderate-to-severe ipsilateral shoulder pain among the thoracoctomy cohort was 15.8% (3/19). Of the 36 VATS procedures audited, 7 patients (19.4%) received infiltration of their phrenic nerve, none of whom reported postoperative ISP. Of the remaining twenty-nine patients who did not receive phrenic nerve infiltration, there were 4 cases of moderate-to-severe ipsilateral shoulder pain (11.1%). Four of the 5 patients (80%) who underwent VATS-guided mini-thoracotomies received phrenic nerve infiltration intraoperatively. Three patients reported moderate-to-severe ISP and of these 3 patients, 2 patients had phrenic nerve infiltration, and 1 patient did not receive infiltration. Overall, there were no statistically significant differences in rest or dynamic pain scores across the surgical groups at any time point. Mann-Whitney test revealed that the participants with ISP were significantly older than those without ISP (p = 0.006). However, there were no significant differences in sex or body mass index between those with and without ISP. The authors observed a lower (15.8%) incidence of moderate-to-severe ISP among their thoracotomy patients than reported in prior literature. Injection of local anesthetic into the phrenic nerve fat pad at the level of the diaphragm appeared to be an effective and safe surgical intervention that may eliminate a significant cause of ISP. None of the VATS patients who received phrenic nerve infiltration experienced ISP. Postoperative pain in VATS is expected to be reduced by avoiding the use of a rib spreader, severing of the intercostal nerves, and division of muscle tissue, which may account for the lower observed rates of ISP in the VATS cohort who did not receive phrenic nerve infiltration. Further randomized controlled trials are warranted to establish if patients undergoing various VATS procedures benefit from this intervention.

Clinical Aspects of Cervicogenic Headache

Cervicogenic headache (CEH) is a lateralized non-pulsative headache syndrome caused by cervical spine disorders. The headache is initiated in the neck, which subsequently spreads to the occipital, frontal, and orbital regions, and is accompanied by ipsilateral shoulder pain. The prevalence of CEH is considered to be 15-20% among cases of chronic headache. With regard to the mechanism of CEH, convergence of upper cervical nerves and trigeminocervical complex might play an important role. However, CEH in many patients has been reported to be associated with middle to lower cervical disorders, which cannot be explained by this theory. We therefore proposed the possibility that the condition reported here is another type of CEH. The treatment of CEH requires a multidisciplinary approach, because pharmacological treatment is often ineffective. (Received August 16 2019; Accepted November 25, 2019; Published March 1, 2020).

Post-thoracotomy ipsilateral shoulder pain: What should be preferred to optimize it - phrenic nerve infiltration or paracetamol infusion?

Background:Post thoracotomy ipsilateral shoulder pain (PTISP) is a distressing and highly prevalent problem after thoracic surgery and has not received much attention despite the incidence as high as 85%.Objectives:To study the effect of phrenic nerve infiltration with Ropivacaine compared to paracetamol infusion on PTISP in thoracotomy patients with epidural analgesia as standard mode of incisional analgesia in both the groups.Study Design:Prospective Randomised and Double Blind Study.Methods:126 adult patients were divided randomly into 2 groups, “Group A (Phrenic Nerve Infiltration Group) received 10 mL of 0.2% Ropivacaine close to the diaphragm into the periphrenic fat pad” and “Group B (Paracetamol Infusion Group) received 20mg/kg paracetamol infusion” 30 minutes prior to chest closure respectively. A blinded observer assessed the patients PTISP using the VAS score at 1, 4, 8, 12 and 24 hours (h) postoperatively. The time and number of any rescue analgesic medication were recorded.Results:PTISP was relieved significantly in Group A (25.4℅) as compared to Group B (61.9℅), with significantly higher mean duration of analgesia in Group A. The mean time for first rescue analgesia was significantly higher in Group A (11.1 ± 7.47 hours) than in Group B (7.40 ± 5.30 hours). The number of rescue analgesic required was less in Group A 1.6 ± 1.16 as compared to Group B 2.9 ± 1.37 (P value <0.5).Conclusions:Phrenic Nerve Infiltration significantly reduced the incidence and delayed the onset of PTISP as compared to paracetamol infusion and was not associated with any adverse effects.

The effect of interscalene block on ipsilateral shoulder pain and pulmonary function in patients undergoing lung lobectomy: A randomized controlled trial.

Background:Postoperative ipsilateral shoulder pain occurs in 37% to 68% of patients undergoing a thoracotomy. We examined whether interscalene brachial plexus block using a lower concentration of local anesthetic would reduce the incidence of post-thoracotomy ipsilateral shoulder pain with assessment of pulmonary function in patients who underwent a lung lobectomy.Methods:Forty-four patients who underwent a lung lobectomy were randomly assigned to either the control or the interscalene block group. Single-shot interscalene block on the surgical site side was performed using ropivacaine 0.25% 10 mL including dexamethasone 5 mg under ultrasound guidance in the interscalene block group. Lobectomy and continuous paravertebral block were performed under general anesthesia. The presence of ipsilateral shoulder pain and postoperative adverse events were assessed. Pulmonary function tests were performed preoperatively, the day after surgery, and the day after removing the chest tube.Results:The incidence of ipsilateral shoulder pain was significantly lower in the interscalene block group than in the control group (54.5% vs 14.3%, P = .006) with an overall incidence of 34.9%. Postoperative adverse events were similar between the groups, with no patients presenting symptoms of respiratory difficulty. Significant reductions in pulmonary function were observed in all patients after lobectomy; however, no significant difference in any of the pulmonary function test variables was observed postoperatively between the groups.Conclusions:Interscalene block using 10 mL of 0.25% ropivacaine including dexamethasone 5 mg reduced the incidence of post-thoracotomy ipsilateral shoulder pain and did not result in additional impairment of pulmonary function.

Comparative study on the analgesic effect of acute ipsilateral shoulder pain after open thoracotomy between preoperative ultrasound guided suprascapular nerve block (SNB) and intraoperative phrenic nerve infiltration (PNI) in cancer lung patients

IntroductionAcute ipsilateral shoulder pain (ISP) is a common complaint in patients after thoracotomy. The incidence ranges from 21% to 97%. Unfortunately, clinical studies did not put enough focus on ISP post thoracic surgery. Aim of the workThis study was designed to compare the effectiveness of suprascapular nerve block (SNB) and phrenic nerve infiltration (PNI) for controlling ISP. Patients and methodsOne hundred and thirty-five lung cancer patients (135) scheduled for open-lung surgery were randomly allocated into three equal groups; control group: received thoracic epidural with general anesthesia, suprascapular group: (SNB) one hour before the operation with 10 ml bupivacaine plus thoracic epidural with general anesthesia and phrenic nerve group: (PNI) was performed by the operating surgeon with 10 ml bupivacaine plus thoracic epidural with general anesthesia.The visual analogue score (VAS) of ISP, rescue of ketorolac for break through shoulder pain, peak expiratory flow rate (PEFR) and arterial blood gases were measured every 6 h postoperatively for 48 h. ResultsThe VAS, rescue doses of ketorolc and PEFR were significantly lower in the phrenic nerve group (P-value <0.05). There was no statistically significant difference between the three groups postoperatively as regards arterial blood gases (P-value >0.05). ConclusionPNI is more effective than SNB for ISP.

Ipsilateral shoulder pain in patients following lung resection in the decubitus position.

To examine the frequency, influencing factors and clinical course of shoulder pain in patients following lung resection. Thoracoscopes have been introduced in the surgical treatment of lung cancer and allow for less invasive surgery with a minimal incision. However, decubitus position-related shoulder pain on the operated side has not yet been investigated. A longitudinal descriptive study. Patients who underwent lung resection in the decubitus position. Patients were interviewed 2days before surgery and once daily for 5days after surgery. Interview items included background data, the concomitant use of epidural anaesthesia, operative duration, the presence of preoperative shoulder stiffness (excluding shoulder pain), type of surgery and site of operation. The intensity of pain was approximately 5 on an 11-point numerical rating scale. Descriptive statistics on patient backgrounds were obtained using SPSS Statistics 22 for Windows. Of the 74 patients who underwent lung resection in a decubitus position, 30 (40.5%) developed shoulder pain on the operated side. The highest rating occurred 1day after surgery and decreased over time. The following two factors were found to influence shoulder pain on the operated side: operative duration (Z=-2.63; p=.01) and the presence of preoperative shoulder stiffness (excluding shoulder pain) (χ2 =4.16; p=.04). This study demonstrated that approximately 40% of patients who underwent lung resection in the decubitus position developed shoulder pain. The presence of postoperative shoulder pain was related to both the duration of the operation and to the presence of preoperative shoulder stiffness. Although the shoulder pain resolves within 4days, it causes the patient additional discomfort and distress. Therefore, further research is needed on positioning for thoracotomy in order to investigate ways to reduce or eliminate this complication of lung surgery.

The Effectiveness of Intravenous Parecoxib on the Incidence of Ipsilateral Shoulder Pain After Thoracotomy: A Randomized, Double-Blind, Placebo-Controlled Trial

To determine the incidence of ipsilateral shoulder pain (ISP) with the therapeutic use of parecoxib compared with a placebo after thoracotomy. A prospective, randomized, double-blind, placebo-controlled trial. A tertiary-care university hospital. Adult patients undergoing an elective thoracotomy between June 2011 and February 2015. Patients were allocated randomly into the parecoxib group (n = 80) and the control group (n = 80). In the parecoxib group, 40 mg of parecoxib was diluted into 2 mL and given intravenously 30 minutes before surgery and then every 12 hours postoperatively for 48 hours. In the control group, 2 mL of normal saline was given to the patients at the same intervals. A numerical rating scale was used to assess the intensity of ISP at 2, 6, 12, 24, 48, 72, and 96 hours after surgery. Intravenous morphine (0.05 mg/kg) was used as the rescue medication for ISP during the 96-hour period. Baseline characteristics of patients in both groups were comparable. Patients in the parecoxib group had a significantly lower incidence of ISP, both overall (42.5% v 62.0%, p = 0.014) and of moderate-to-severe ISP when compared with the control group (26.2% v 49.4%, p = 0.003). Parecoxib reduced the risk of ISP by a statistically significant 32% (risk ratio, 0.68; 95% confidence interval, 0.50-0.93, p = 0.016). There were no significant differences in the occurrence of adverse effects between the groups. Intravenous parecoxib significantly can reduce the incidence and severity of ISP after thoracotomy.
