Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Participants will be randomly assigned to three groups:
* First group will undergo internal intercostal nerve block
* Second group will be given external intercostal nerve block
* Third group will have an intercostal catheter Researchers will compare the three groups to see their impact on post-operative pain management in uniportal VATS.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1. To study post-VATS complications, such as: postoperative air leak, post-operative pain, hypoxemia, atelectasis, bleeding, wound infection, pneumonia, Deep Vein Thrombosis, pulmonary embolism and their association with the different approaches of ICNBs.
2. To address the cost-effectiveness of the intercostal nerve block approaches.
3. To study the participants' level of satisfaction after VATS following each procedure of ICNB.
4. To address the relationships between the intercostal nerve block approaches and participants' characteristics such as age, gender, BMI, medical and surgical history, smoking, and alcohol history.
This study is a randomized controlled trial that will take place at Al-Ahli Hospital and Saint Joseph Hospital. The trial will involve 90 participants, who will be randomly assigned to three groups. Of these, group 1 will include 30 participants who'll receive an internal intercostal nerve block, group 2: 30 participants will receive an external intercostal block, and group 3 are the 30 participants who will have an intercostal catheter inserted.
Data will be collected from the participants' themselves through a questionnaire before the surgery. The participants will be followed up after the surgery (3, 6, 24 hours post-operatively) in order to obtain the numerical rating scale. A written informed consent will be sought.
Data Analysis will be done through International Business Machines (IBM) Statistical Package for Social Sciences (SPSS) for Windows Version 16.

Study Groups

External intercostal nerve block
30 participants will be randomised for the External Intercostal block will receive a mixture of analgesics (Marcaine 3mg /kg 0.5%, Lidocaine 2% 10 cc, Dexamethasone 4 mg, 30 cc of Normal Saline (NS) 0.9%, through: Identifying the targeted intercostal spaces: The 3rd-7th by applying digital palpation and indentation of these spaces using the surgeon's fingers and the camera. After identifying the desired spaces, they will use 10 cc syringe connected to 23 Gauge needs, the needle will be applied externally into the chest wall, advancing it with negative pressure, making sure to keep the needle perpendicular to the chest wall to avoid injury to the intercostal neurovascular bundle, advancing the needle while keeping negative pressure, and being closer to the upper border of the ribs. Once the indentation of needle into the pleural is seen, they aspirate again to make sure that they are not into blood vessels, then they will inject 8 cc into each intercostal space.
External Intercostal Nerve Block
External ICNB: A mixture of analgesics will be given through a needle inserted in the intercostal space from outside the chest wall.
Internal intercostal nerve block
30 participants will be randomised for the Internal Intercostal block will receive a mixture of analgesics (the investigators will use a mixture of local analgesics containing: Marcaine 3mg /kg 0.5%, Lidocaine 2% 10 cc, Dexamethasone 4 mg, 30 cc of Normal Saline (NS) 0.9%), through:
-Using the blue color butterfly needle, 23 gauge, The needle will be introduced into the thoracic cavity under the thoracoscopic control and vision, Identification of the intercostal spaces: The third down to the seventh, total of 5 intercostal spaces, the needle will be introduced under vision into the intercostal spaces, avoiding the intercostal artery or veins, aspiration to make sure that they are not into blood vessels, then 10 injecting 8 cc of the analgesic mixture into each of the intercostal spaces, making sure to see the pleura over the intercostal space bulging to indicate that the analgesic is not injected into deeper muscular layers.
Internal Intercostal Nerve Block
Internal ICNB: A mixture of analgesics will be given through a needle inserted in the intercostal space inside the chest wall under direct thoracoscopic vision.
Intercostal catheter
30 Participants will be randomised for the Intercostal Catheter, the investigators will use an epidural catheter set, they will apply the catheter to one - two intercostal spaces higher that the VATS incision. The investigators will start by applying the needle from outside, into the desired intercostal space, once they see the indentation of the needle. They will inject 5 - 10 cc of normal saline to distend the intercostal space, then they will remove the stylet part and they will introduce the catheter, after making sure that there is at least 3 centimeter of the catheter into the intercostal space, they will remove the needle, making sure not to move the catheter, then they will tunnel the catheter under the skin for 2 cm , the participant will receive the 15 cc of the previously mentioned mixture every 8 hours for two to three days.
Intercostal Catheter
Intercostal Catheter: it will be put 1-2 intercostal spaces above the VATS incision, and the participant will receive the 15 cc of the previously mentioned mixture every 8 hours for two to three days.
