Efficacy, Safety and Re-occurrence of Pneumothorax and Hydro-pneumothorax With Talc and Pyodine Pleurodesis

2019-10-23 13:11:49 | BioPortfolio




Pneumothorax and hydro-pneumothorax are the most common thoracic injuries and poses a risk of serious morbidity.To prevent the lung from collapsing in such condition, pleurodesis procedure is performed either with surgical pleurodesis,or chemical pleurodesis which adheres outside the lung to the inside chest cavity. The common chemicals that are used are bleomycin, tetracycline, minocycline, slurry of talc and povidoneiodine.

In developed countries, the most common chemical agent used is talc, tetracycline derivatives and bleomycin. However, its clinical results depend on the level of collapse of the lung on the affected side.Internationally, for spontaneous pneumothoraces, talc is the best chemical for pleurodesis procedure which is insufflation through thoracoscopy. However its safety is debateable especially in acute respiratory disease after its administrationwhich made it null and vide consequently. Secondly, in developing countries,medical grade talc availability and affordability remains a constraint. The other suitable chemical is Iodopovidone which is inexpensive and widely used as topical antiseptic in many countries. It also hasshown a safe and effective chemical agent for pleurodesis procedure.


To determine the efficacy, safety and reoccurrence rate of in pneumothorax and hydro-pneumothorax patients after procedure with talc and pyodine pleurodesis: A comparative study.


On the basis of inclusion criteria, the selected 104 patients will be grouped (talc and pyodine) through Non probability, purposive sampling method. In each group 52 willing participants will be included without considering the size of pneumothorax. Six readings of each individual participant will be taken (3 before procedure and 3 after procedure for each group) for pulse and respiratory rate, fever, and total counts of leukocyte. Pain will be assessed on analogue scale. The readings will be taken with 8 hours gap apart. Re-occurrence will be determined after 6 months period of the procedure along with complications if any. The results of both groups will be compared for Efficacy, Safety and Re-occurrence of Pneumothorax and Hydro-pneumothorax.

Pneumothorax and hydro-pneumothorax are the common thoracic injuries which have a severe risk of morbidity. In such a condition either gas or air remains in pleural cavity, a space between visceral and parietal pleura of lung1or air and fluid both are present where air fluid level can be seen in upright chest x-ray of the patient2. To prevent the lung from collapsing in such condition, pleurodesis procedure is performed with surgical or chemical agents which adheres outside the lung to the inside chest cavity1. In surgical pleurodesis, removal of the parietal pleura is done which is an effective way of getting stable pleurodesis. In chemical pleurodesis, the space between the parietal and visceral layer is closed through chemical to prevent further accumulation of fluid. The common chemicals that are used are bleomycin, tetracycline, minocycline, slurry of talc and povidoneiodine

Rational of the study:

There is a little local knowledge is available for use of pyodine which is as effective as talc. If it is determined then it could be easily used in rural areas of the country with a safety involvement. Through determining the efficacy, safety and reoccurrence of pyodine in compare with talc pleurodesis procedure in pneumothorax and hydro-pneumothorax, in patients accordance with systemic inflammatory response syndrome. If the safety, efficacy and less rate of reoccurrence of pyodine are determined as compared to gold standard talc, it will be help fill in treating patients at a remote area where the facility of talc is not available. (Talc chemical lost its validity within 24 hours)


To determine the efficacy, safety and reoccurrence rate of Pyodine compared with talc pleurodesis inpatients with pneumothorax.


Null Hypothesis:

Talc pleurodesis is more safe having less chances of reoccurring in pneumothorax patients compared to pyodine pleurodesis.

Alternate hypothesis:

Pyodine pleurodesis is as safe, low cost, and easily available with less chances of reoccurring in pneumothorax patients compared to Talc pleurodesis.


Study Duration:

Nine months after the approval of synopsis (October 2019 to March 2020)

Study design:

Randomize control trail

Sampling Method:

Non-probability, purposive sampling method

Study setting:

Medical Unit 3, civil hospital, Karachi

Study Instruments:

Structured questionnaire for data collection see in Appendix A

Sample size:

Using sensitivity and specificity in studies (Dr Lin Naing), confidence level 95%, with margin of error 0.05, sample size of the study will be 104 cases divided equally in two groups' i.e.52 in each group.

Data collection procedure:

Study will be conducted after approval of synopsis from Institutional Review Board (IRB), of Dow University of Health Sciences. A written informed consent will also be taken from the participants to put them on Talc or Pyodine group. All patients fulfilling the inclusion criteria will be placed through non probability purposive sampling in groups for pyodine and talc pleurodesis. From all selected patients, 3 readings for pulse and respiratory rate, fever and total leukocyte count for 24 hours at a gap of 8 hours will be recorded prior to procedure. Pain threshold will be determined through visual analogue score 0 to 10 grade. During procedure, it will be assured that bubbling has stopped and lung has expanded. In case of hydro-pneumothorax, the fluid is less 100 ml. After that chest tube pipe will be raise upper the bed level. Than two ampoules of xylocaine injection and 40 ml of 0.9 % saline will be taken. After one or two min, already prepared talc slurry will be instilled in chest tube. In patients selected for pyodine, 40 ml pyodine and 20 ml 0.9% saline will be inserted slowly in chest tube slowly. The patient's tube will remain raised for four to six hours from bed level. After procedure, readings for fever, pulse rate, respiratory rate, and pain threshold of patient with repeated readings with 8 hour gap for 24 hour will be recorded. After repeat chest x-ray, tube will be taken out. Reading of total leukocyte count will be taken after 24 hours of pleurodesis. Follow up will be done for 6 months and reoccurrence rate will be calculated after six month with repeating chest x-ray. Failure of pleurodesis will be determined and put in the result. All the readings will be recorded on the proforma.

Data analysis plan:

The data collected on proforma will be entered in SPSS version 21.0. For each group data, Mean ± SD will be calculated and statistical significance will be determined through independent sample T-Test for quantitative variables like age, pulse and respiratory rate, fever, and total leukocyte count. The pain scores will be determined. The before and after procedure readings in both groups will be analyzed and sensitivity and specificity of pyodine will be determined for with Talc as a gold standard. For qualitative data kike gender, pain score, percentage and frequency will be determined. Confounding and biases will be controlled through strict follow of inclusion criteria.

Ethical Issues:

The ethical approval will be taken from the IRB of Dow University of Health Science, Karachi. A written informed consent will also be taken from the individual participants. The information so collected will be kept in lock and key and nobody other than the researcher and his supervisor will be reached to the data. Right of with draw from the study will be given to all participated patients.

Medical and Biotech [MESH] Definitions

An accumulation of air or gas in the pleural space, which may occur spontaneously or as a result of trauma or a pathological process, or be introduced deliberately ( = PNEUMOTHORAX, ARTIFICIAL). (Dorland, 27th ed)

A generic term for a variety of compounds that contain silicon, oxygen, and magnesium, and may contain hydrogen. Examples include TALC and some kinds of ASBESTOS.

Surgical treatment of pulmonary tuberculosis whereby the lung is totally or partially, temporarily or permanently, immobilized. The procedure was based on the popular concept that collapsing the affected portion of a tuberculous lung allowed the infected area to rest and thereby recover. At the beginning of the 20th century artificially induced pneumothorax (PNEUMOTHORAX, ARTIFICIAL) was popular. Later a variety of other techniques was used to encourage collapse of the infected portion of the lung: unilateral phrenic nerve division, PNEUMONOLYSIS, pneumoperitoneum (PNEUMOPERITONEUM, ARTIFICIAL), and THORACOPLASTY. Collapse therapy has declined since the advent of antitubercular chemotherapy. (Stedman, 25th ed; from Sabiston Jr, Textbook of Surgery, 14th ed, p1733-4)

Finely powdered native hydrous magnesium silicate. It is used as a dusting powder, either alone or with starch or boric acid, for medicinal and toilet preparations. It is also an excipient and filler for pills, tablets, and for dusting tablet molds. (From Merck Index, 11th ed)

Surgical creation of an opening (stoma) into the chest cavity for drainage; used in the treatment of pleural effusion, pneumothorax, hemothorax and empyema.
