Brief Summary:
The aim of this prospective, single blinded, comparative pilot study is to evaluate U/S guided serratus anterior plane catheter block (SAPB) versus patient-controlled analgesia (PCA) on the emergence of post - thoracotomy pain syndrome (PTPS). The investigator's assumed hypothesis is that; SAPB is an effective thoracic analgesic technique that may reduce the development of PTPS.

Thoracic Neuritis Procedure: Serratus anterior plane catheter block Procedure: Patient controlled analgesia Not Applicable

Detailed Description:
Lung cancer has the highest incidence of all malignancies worldwide & represents about 13% of all cancer victims. Lung cancer still represents the first cause of cancer deaths and lung resection surgeries could be the main therapeutic procedure. Hence, the number of thoracotomies is progressively increasing with more & more post- thoracotomy pain . Together with amputation, thoracotomy is considered the main etiology of severe & long-term acute and chronic post-surgical pain syndromes (CPSP). The prevalence of post - thoracotomy pain syndrome (PTPS) is variable (30-50%). The international association for the study of pain (IASP) has defined PTPS as "pain that recurs or persists along the thoracotomy scar at least 2 months after the procedure".Besides, PTPS is mostly described with neuropathic manifestations along the thoracotomy scar, mammary & submammary ipsilateral scapular & interscapular areas. Pain is often aching, burning with tingling, numbness, pruritis plus sensory loss and/or hypoesthesia.Preemptive post-thoracotomy analgesia is mostly multimodal & integrates both systemic & regional techniques. Systemic drugs (either given parenterally or through patient controlled - analgesia "PCA") include, NSAIDs, Cox - II inhibitors, paracetamol, opioids, ketamine (as N-methyl-D- aspartate blocker), gabapentins & pregabalin, selective serotonin re-uptake inhibitors and/or duloxetine .Regional analgesic techniques include thoracic epidural analgesia (TEA) which, is considered by many as the gold standard analgesic mode for post-thoracotomy pain .Other regional analgesic techniques are paravertebral analgesia (PVB), intercostal nerve blocks and intrapleural analgesia.Recently SAPB has been practiced more widely as an U/S - guided, simple technique of effective post-thoracotomy analgesia which is comparable with standard techniques such as TEA and PVB.

Arm Intervention/treatment
Active Comparator: Pump based patient controlled analgesia
Analgesia is maintained using disposable silicon ballon pump "Accufuser" containing morphine 0.2 mg/ml, 8mg ondansetron plus and 180 mg ketorolac. The infusion rate is 5 ml / h and lockout interval of 15min. the hourly delivered morphine dose is 1-1.8 mg & the pump is sufficient for about 60 hours according to patient response.
Procedure: Patient controlled analgesia
The use of patient controlled analgesia through a pump aiming to reduce the development of postthoracotomy pain syndrome

Active Comparator: serratus anterior plane catheter block
Linear ultrasound transducer (superficial) 6-12 MHz is utilized to count the ribs up to 4th or 5 th rib in the mid-axillary line. Musculature of thoracic wall is identified sonographically,an echogenic needle "14-16 G, 100 mm" is inserted in plane with the U/S probe towards the plane deep to the serratus anterior muscle. Under real - time U/S, single shot of 20ml contrast medium "iohexol = omnipaque" 150 mg I2 / ml is injected to check the plane and level (T3-T8/9) of SAPB.A reinforced radiopaque catheter is threaded through the needle and its final position underneath the plane of serratus anterior muscle is confirmed fluoroscopically. 20ml 0.25% levobupivacaine (Chirocaine).Analgesia is maintained using 0.125% levobupivacaine infusion at a rate of 7-12 ml/h according to patient response.
Procedure: Serratus anterior plane catheter block
Ultrasonographic guided placement of a catheter under the serratus anterior muscle in cases of open thoracotomies for chest malignancies in an attempt to reduce the emergence of postthoracotomy pain syndrome.

Primary Outcome Measures :
  1. Assessment for the possible emergence of post - thoracotomy pain syndrome . [ Time Frame: changes in 4 and 12 weeks . ]
    The neuropathic PTPS cases are screened using the grading system for neuropathic pain (GSNP). Positive cases of PTPS having neuropathic component is grade 3 (probable) or 4 (definite) i.e GSNP ≥3 .

Secondary Outcome Measures :
  1. Assessment of patient daily activity and functional capacity. [ Time Frame: changes in 4 and 12 weeks . ]
    Activity of daily living score (ADL score).It comprises 6 basic daily activities (feeding, toilet, bathing, dressing, grooming and walking) with each item is scored either 1= need no help, 2=need some help, 3=need complete help

  2. Assessment of patient's quality of life. [ Time Frame: changes in 4 and 12 weeks . ]
    Flanagan quality of life scale.A 16 items (domains) questionnaire with each item weights 1 to 7 points.the total score ranges from 16 to 112 .Higher values indicate better quality of life .It will be explained to the patients by the pain physician and the total score will be calculated and recorded
