Gynecologic Patients

Background: The spinal block has become a favorable technique for gynecologic surgery. However, the level of sympathetic blockade results in weak diaphragm and respiratory muscles as well as cough impairment. Investigators were curious to assess patients’ respiratory functions after spinal anesthesia. Materials and Methods: One hundred forty-five gynecologic patients undergoing elective, exploratory laparotomy with spinal anesthesia were included. The blowing practice of a Mini Wright Peak Flow Meter was performed until patients became comfortable with it. A given patient blew the device three times, and the best value was chosen to assess peak expiratory flow rates (PEFRs): prior to surgery (P1), after the spinal block (P2), and in the recovery room (P3). Results: At the thoracic blockade level as T was 4 or less and T was greater than 4, PEFR at P1, P2 and P3 were 285.9±5.9, 222.3±4.9, and 216.4±6.4 mL, and 302.8±7.7, 224.9±6.4, and 203.4±8.4 mL, respectively. The PEFRs showed no significant differences among the levels of blockade at the ward (p=0.082), the operating theater (p=0.744), and the recovery room (p=0.211). Though P3 seemed to fall, there was no marked difference between P2 and P3 (p=0.224). However, either P2 or P3 appeared to decrease sharply (p<0.001) in comparison with P1. Conclusion: A Mini Wright Peak Flow Meter can be used as a bedside device to measure PEFRs. The substantial decrease of PEFR was related to the level of sympathetic blockade after spinal anesthesia.

Objective This study aims to compare peak expiratory flow mea-surement by peak flow meter and electronic spirometer in healthyelementary school children.Methods This was a cross-sectional study performed in an el-ementary school near Cipto Mangunkusumo hospital (SDNPegangsaan 01). The study group consisted of healthy childrenaged 6-12 year old. Data regarding identity and history of illnesswas taken in each subject. Routine physical examination was per-formed and recorded. Each subject performed lung function testsby means of electronic spirometer AS-7 as well as by Mini-Wrightpeak flow meter. The subject should perform a minimum of threemaneuvers for each method where only the best result was re-corded. Method comparison test to assess agreement betweentwo methods was employed in this study.Results There were 10 males and 15 females enrolled in this study.None of the subjects currently have any respiratory symptoms andsigns. This study found that the mean peak expiratory flow (PEF) byspirometer was 226.8±73.13 L/min while by peak flow meter was223.0±45.05. Mean difference between spirometer and peak flowmeter measurements is 6.2 with standard deviation of 60.82. Thesevalues resulted in limits of agreement of -115.44 to +127.84 L/min.Conclusions This study finds disagreement between electronicspirometer and Mini-Wright peak flow meter in measuring peakexpiratory flow, therefore these two devices cannot be usedinterchangeably. Mini-Wright peak flow meter still has a role inhome monitoring, but the physician should interpret the resultscarefully.

Background: In this era of globalization one of the growing industries is the construction industry and there are various occupational problems faced by the workers especially in Asian countries mostly in India; the problems are related to both physical and mental health. All the construction sites generate high concentration of dust particles from cement, silica, asbestos, concrete, wood, stand and stand that causes respiratory problems in the workers. PEFR is the maximum air that is generated after forceful expiration, after full lung inspiration. So if there is any accumulation of dust particles the PEFR decreases as the elasticity of lungs to recoil is distrusted due to the lodged particles. Material and Method: A descriptive observation study was carried out on 50 building construction workers. The purpose of the study was explained and informed consent was taken. The PEFR was measured using peak expiratory flow meter. The data was analyzed using standard statistical software. Result: The procedure of using peak flow meter that was carried out for 3 times and the highest value from the three was considered as peak flow rate, using statistical method mean and standard deviation were calculated. The mean of Peak Expiratory Flow Rate is 321.1 L/min. Conclusion: This study concluded that the peak expiratory flow rate is reduced in building construction workers those who are working for than 2 years on the construction sites. Key words: construction workers, occupation diseases, PEFR, peak expiratory flow meter.

Home-monitoring of peak expiratory flow rate using the mini-Wright peak flow meter is a useful technique for determining whether or not unexplained respiratory symptoms are caused by asthma. It is of particular value when airflow obstruction cannot be demonstrated at the time of consultation.

ABSTRACT Peak expiratory flow rate (PEFR) is a simple, reliable, and easily reproducible and measurable lung function test. It has not been formally assessed whether the PEFR values measured with peak flow meter are in close correlation with the values measured by digital spirometer. The present study is carried out to determine whether there is a significant difference between the PEFR values derived from digital spirometer and peak flow meter in patients with respiratory symptoms.
