CHARLES HORSE WAS ADMITTED TO THE HOSPITAL TODAY WHERE HE PRESENTED HIS CHIEF COMPLAINTS AND RECENT MEDICAL HISTORY. THIS PATIENT IS A FIFTY-THREE YEAR OLD WHITE MALE. MR. HORSE IS A RUGGED INDIVIDUAL WITH AN EXTENSIVE HISTORY. HE SMOKES 1 PACK OF CIGARETTES PER DAY FOR MORE THAN TWENTY FIVE YEARS. AS A SINGLE LUMBERJACK HIS DIET HAS RELIED HEAVILY ON FAST FOODS. OVER THE PAST SEVERAL MONTHS MR. HORSE REPORTED HE HAD GRADUALLY BEEN EXPERIENCING PAIN IN THE LEFT LEG. THESE PAINFUL SYMPTOMS INCREASED TO A POINT WHERE HE CANNOT WALK MORE THAN TWO CITY BLOCKS WITHOUT SEVERE CRAMPING IN HIS LEFT LEG. HE STATES HE MUST STOP, SIT AND RUB HIS LEG UNTIL THE CRAMPING STOPS. MR. HORSE HAS GRADUALLY ADJUSTED HIS ACTIVITIES AROUND THESE SYMPTOMS. THIS MORNING, MR. HORSE AWOKE FROM A DEEP SLEEP TO SUDDEN, SEVERE PAIN IN THE LEFT LEG. THE PAIN DIMINISHED SLIGHTLY WHEN HE SAT UP AND HUNG HIS LEGS OVER THE SIDE OF THE BED. HE NOTICED CHANGES IN SKIN COLOR AND TEMPERATURE. CONCERNED ABOUT THE SUDDEN CHANGES, MR. HORSE HEADED DIRECTLY TO THE EMERGENCY ROOM. WHEN YOU ASSESS THIS PATIENT ATTENTION IS DIRECTED TOWARD HIS LEFT LEG. THE SKIN IS COOL TO TOUCH. ASSESSING PERIPHERAL PULSES YOU NOTE THAT HIS FEMORAL AND POPLITEAL PULSES ARE STRONG AND PALPABLE BILATERALLY. HOWEVER, HIS POSTERIOR TIBIAL AND DORSALIS PEDIS PULSES ON THE LEFT LEG ARE NOT PALPABLE. A DOPPLER READING INDICATES THERE IS SOME DEGREE OF CIRCULATION PRESENT. NAIL BEDS ARE CYANOTIC; CAPILLARY FILLING IS SLOW (> 3 SECONDS) IN ALL DIGITS ON THE LEFT FOOT. ATTEMPTING TO IMPROVE MR. HORSE’S COMFORT, THE NURSE ELEVATES HIS FEET. MR. HORSE REPORTS THE PAIN IS SIGNIFICANTLY WORSE! LEFT LEG DISCUSSION 1. WHAT INFORMATION DOES INSPECTION OF THE PATIENT’S LEG PROVIDE? PALE a) COLOR OF SKIN b) COLOR OF NAIL BEDS CYANOTIC 2. WHAT CAN PALPATION TELL YOU ABOUT THIS PATIENT’S CONDITION? a) TEMPERATURE COOL TO TOUCH INDICATES BLOOD FLOW, SENSITIVITY b) PULSES BLOOD FLOW, WEAK PULSES (+) FEMORAL, (+) POPLITEAL PULSES CHECK FLOW WITH DOPPLER 3. WHAT POSITION WOULD BE THE MOST COMFORTABLE FOR MR. HORSE? SUPINE OR DANGLE 4. WHAT PROBLEM DO YOU THINK MR. HORSE HAS WITH HIS LEFT LEG? ARTERIAL INSUFFICIENCY 5. WHAT WOULD PREDISPOSE MR. HORSE TO DEVELOPING THIS TYPE OF PROBLEM? SMOKING, LIPIDS, PROBABLY CAD, POSSIBLE DAMAGE TO INTIMAL LAYER OF BLOOD VESSELS 6. WHAT IS THE CLINICAL TERM FOR A CONDITION CAUSING PERIODIC CRAMPING BROUGH ON BY WALKING? INTERMITTANT CLAUDICATION 7. WHAT ARE THE 5 P’s YOU SHOULD LOOK FOR? PAIN PALLOR PULSELESSNESS PARALYSIS PARESTHESIA THIS IS A SURGICAL EMERGENCY! FOLLOWING A SUCCESSFUL REVASCULARIZATION PROCEDURE, MR. HORSE WAS D/C’d TO HOME IN GOOD CONDITION. HIS LEFT LEG WAS WARM, PINK IN COLOR AND ALL TOES WERE MOBILE. MR. HORSE WAS PLACED ON MEDICATIONS TO MANAGE HIS CHF, WHICH WAS DISCOVERED DURING IHIS MEDICAL HISTORY AND PHYSICAL EXAM. TWO WEEKS LATER THIS PATIENT RETURNED TO THE HOSPITAL… PRESENTING WITH DYSPNEA, ORTHOPNEA AND BILATERAL +3 PITTING EDEMA. MR. HORSE WAS READMITTED TO THE HOSPITAL WITH A DX OF CHF. DIGOXIN (A CARDIOTONIC) WAS STARTED AND LASIX (A DIURETIC) ALSO WAS ADDED TO HIS MEDICATION PROFILE. ONCE AGAIN MR. HORSE WAS D/C’d TO HOME AND PROVIDED WITH A HOME HEALTH AIDE TO ASSIST HIM WITH HIS ADL’s. HE WAS INSTRUCTED TO REMAIN ON BED REST FOR ONE WEEK. HE IS SEEN BY THE VISITNING NURSE IN HIS HOME ON F/U TO ASSESS HIS STATUS. THE NURSE TAKES NOTICE OF MR. HORSE’S +2 PITTING EDEMA IN HIS RIGHT LEG, EXTENDING FROM THE FOOT TO THE LOWER THIGH. SKIN COLOR IS NOTED TO HAVE A REDDISH/ PURPLE HUE AND THE SURFACE TEMP IS INCREASED LOCALLY. THE LIMB IS TENDER TO TOUCH AND PAIN INCREASES WITH DORSIFLEXION. THE NURSE ALSO NOTES THAT PERIPHERAL PULSES ARE MODERATELY DIMINISHED ON THE RIGHT SIDE ONLY. MR. HORSE COMPLAINS THAT HIS RIGHT LEG FEELS HEAVY AND THROBS. RIGHT LEG DISCUSSION 1. WHAT DOES INSPECTION OF HIS RIGHT LEG REVEAL? a) SKIN COLOR DUSKY RED b) GIRTH / TENSION (+) SWELLING 2. WHAT DOES PALPATION TELL YOU ABOUT THE STATUS OF HIS RIGHT LEG? a) TEMPERATURE TEMP INDICATES INFLAMMATION b) EDEMA (2+) PITTING EDEMA, VENOUS CONGESTION 3. WHAT DO YOU THINK THE PROBLEM IS WITH MR. HORSE’S RIGHT LEG? (+) DVT 4. WHAT DO YOU THINK CAUSED MR. HORSE’S RECENT COMPLICATIONS? PROLONGED BED REST DUE TO CHF, INACTIVITY, DEHYDRATION FROM LASIX, BLOOD VISCOSITY 5.
